ITB's + GT32 = Fun!

[RBS14]

So some of you already know, but I've been building a turbo setup for the past few months.

Started it up for the first time last night, did a bit of idle smoothing today until my turbo started blowing oil into the exhaust. I'll pick up a pressure reducer tomorrow for my turbo feed line. Turbo is an AMS GT32 and i'm controlling it all with a Haltech E8 (which most of you already know).

Enough talking, more pics:

turbonetics mani and wastegate:

ITB's used to be attached to the intake mani like so:

They're now attached like so. Close up of new plenum too:

I'm dyno tuning it this week to get ready for an event next weekend. So I'll post up a dyno chart or two once I get that done. Even untuned it's still really responsive, like when it was n/a, but now it'll actually make some power. I'm not sure how much boost I'm gonna run yet, but the initial tune will prolly be for about 8psi. Then after the event next week I'll probably go back in and we can tune it up to maybe 1 bar or so. We'll see.

cheers

[Team Rootbeer]

NICE! man, that is sick.......i wanna see the charts! hurry up!

iirc, your using gsx-r throttle bodies right? anywho awsome job on the fab, and the setup

[kouki_s14]

thats sick, nice work. anything done to the internals?

[TheTimanator]

nice work. Can't wait to see the dyno. Any reason for the really small intercooler?

[m0rex]

Thats f'ing sick. Mad props.

[luckyrb13]

That looks beautiful. Id love t osee that set up in person.Iam also in the bay Area. Are you going to go to the altamont event?:wackit:

[SpeedMonkeyInc]

Rock. Settled on a target boost level yet?

[Nachtmensch]

thats fucking nuts!!!! i want!

dyno?

[alexchanman]

crazy setup man but that welding is suspect.:bigok:

[that180guy]

looks lik you got real nice clearance with the bmc. is it because of the way u welded the dp? turbo or the manifold?

[TurDz]

Did you get your rear solid endlinks installed? ;)

[RBS14]

Yeah, I'm using gsxr throttle bodies.

Stock internals still save for JWT cams.

Small intercooler because it will still cool efficently up to about 400hp. Any bigger just increases lag.

I'll be at the June 15th altamont event.

I think 8psi to start with then after the event this weekend I'll tune it up to about 1 bar and see how it is. I probably won't run it at that yet, just tune it to that so I can up it whenever I want.

All the TIG welding (aluminum) is beautiful, but the MIG stuff I did is not so great. But I made and tacked together the dp, and a friend welded it up so it's all good and nice. Only ugly stuff is the wastegate dump.

The BMC clearance is because of the mani primarily and the way I made the DP.

haha No I haven't done the rear endlinks yet. I've been spending too much time on the turbo shit. I'll do it soon. Back to suspension setup now.

Cheers

[Pank]

whatever happened to "NA Monsters Only"??

[Dousan_PG]

nice welds jackass haha
then again icant do any better.shutup
looks good

and john says your a biter.
queer! :p
come drive come visit. im lonely scooter.

[250sxdet]

damn that looks sick. nice job dude.

[RBS14]

hahahaha

Tell john I'll bite him.
Are you going to the Industry day? Not to drive obviously but maybe hang out? You should. I'll be there. And Baby and Linda too right? I'll make you feel all warm and fuzzy, I promise.

[L1ama]

You're insane :wackit:

[chibo]

This might sound stupid, but how do ITBs help if they share a common plenum?

[RBS14]

well the plenum is before the TB's so there is no lag between when the TB opens and when the air hits the engine. And the plenum I made flows about 10983572394578 times better than stock. The TB's also equalize pressure so you don't get any cylinders going lean like on stock plenum stuff.

"n/a monsters only". I don't have the $$ to get enough power N/A. And I'm a poser.

[NemeGuero]

They can suck in larger volumes of air. Like they do on bikes and other ITB applications..

They'll most always have an "air box" that supplies air from elsewhere to the ITBs.


I saw this on Ka-T a few days ago.. man I wanna feel what it pulls like..
looks really good man.

Interesting, I don't want to waste your time asking dumb questions so do you know of a good place to read up on ITB turbo applications?
The equalizing pressure makes sense to me but I can't visualize how it accomplishes it for the life of me :newbie:

vvv good idea, corky bell... I've been meaning to get his book.

[wootwoot]

Corky Bell?
Google?

[Pank]

This might sound stupid, but how do ITBs help if they share a common plenum?

the stock rb26dett uses a set of ITB's in a plenum.

[chibo]

the stock rb26dett uses a set of ITB's in a plenum.
I wasn't trying to bash the setup, I was just interested. I know it's been done, the E46 M3 also shares a common plenum with ITBs, as does the E60 M5. I'll also attest to the fact that they sound orgasmic.

[Dousan_PG]

if your going scooter, illl FOR SURE GO! :)

[CaoBoY]

nissan R34 Z-tune special edition. ITB's and a monster motor. BAM. nuff said.
OP-good shit. ITB's are awesome, and so is turbo...best of both worlds. now it should be called "panda-na+turbo=sexygirls and lots of money "

[Ricks15]

Good shit :fruit:

[EchoOfSilence]

You bastard. It looks beautiful... But i still don't understand why the velocity stacks go sa far into the plenum. Are you still in Santa Cruz? I'd love to see these in person


PS: bilingual oil filters make me nervous

[S14DB]

Nice setup.

Grinder and Wire Wheel makes crappy welds look nice. But, it looks like you ceramic coated already.

[mrmephistopheles]

scooterpants - looks like there's some badassery afoot! Can't wait to see what fun this setup is capable of.

[FaLKoN240]

Wow, that set up is straight up GANGSTA. I can't wait to hear it in person. . .again.

[Neejay]

Damn that's nice man. Good job.

Also, you said that that intercooler was good to about 400hp? So why do people get those huge ones with waaaay less power? Or does this have to do with the ITB setup? (Not being an ass, I really just dont understand)

And I like the way the intercooler is in between the headlights (less air travel, and unique to me)

[NemeGuero]

So why do people get those huge ones with waaaay less power?

RICE RICE BABY!!

[95Blue240sx]

Whats gansta is that he doesnt have turn signals on his colum.

Wicked shit thoughhhh

[PoorMans180SX]

DO you have more pics of the ITB setup before the plenum? And how did you hook up the throttle cable? PM me please. I've been wanting to do this for forever!

[axiomatik]

here's his original ITB thread:

http://www.zilvia.net/f/showthread.php?t=68181

[wootwoot]

are you planning on upgrading the radiator with that intercooler stealing a lot of the airflow away?

[Neejay]

are you planning on upgrading the radiator with that intercooler stealing a lot of the airflow away?
That's what I was wondering too, but I would think he has plenty of airflow the regular way (through the front bumper).

Maybe that also had something to do with going with that style intercooler?

[j00ni3]

:faint: post some vids and more pics~~

i like how you did the whole setup... i was thinking about doing something like this hehe...

[sncs14]

I demand event footage ASAP

[meatish]

Haha scoot those are some cute welds.. did you use a $60 stick welder from pep boys?
Just kidding, looks SICK, cant wait to hear it. I'll probably see you at event soon after I get my new car.
Have you finished tuning yet?

[SimpleS14]

Damn that is some nice work Scott. I wish I can see the setup in person and hear the car. I hope your numbers are what your looking for, unlike the ITB project.

[ramblux]

Scott, do you have any audio or video of your original N/A setup? I think people would shit if they haven't had a chance to hear it. It's SICK.

[RBS14]

Everyone else runs huge intercoolers because they either think they need one that big or just like how it looks more than functionality.

Mike, I never got any video with good sound when it was N/A. Oh wells.

Little update. Turbine side oil seal is blown. Fantastic. So I guess I'm not going to the event on sunday, or having my car running in the next anytime soon. Fucking sweet. Goes out for warranty repairs tomorrow.

[SpeedMonkeyInc]

Thats all it took? The seals went out that fast? Garbage. I am sorry.

[RBS14]

Yup. You know how it goes tho. Did you get your turbos back yet?

[SpeedMonkeyInc]

One of them yeah. Car is running great thanks. The smaller turbo that I will end up sticking with is still out. 3 months and still no word.

[BigVinnie]

The equalizing pressure makes sense to me but I can't visualize how it accomplishes it for the life of me :newbie:



It's really very simple to visualize, there just like swirl control valves. Maximum swirl to deliver optimum atomization. Kinda of like OBD and OBD1 KA's with out the super long runners, and an added TB before the runners, more responsive and very much larger than the KA runner scv's too.
This kind of setup should be very jumpy on the throttle responce.
Plus Scott is using velocity stacks everywhere from the turbo to the plenum, unfucking believable....
I can't wait to see speed monkey, Neme, and RBS go head up on the dyno's and the track, and all these guys come outta cali where the ballers play......Big Pimpin....

[ms!3]

your setup is so tight. ive wanted to have itbs and a turbo and ive never seen anybody do it on a 240. now i know that i can do it in my car.

[Neejay]

Fucking fantastic isn't it? Everytime you get close to something, something stupid happens.

[ranisron]

Scott, best of luck to your setup (it is very sweet!). Hope you get your turbo back soon.

and of course, we all want numbers.

big props to you.

[RBS14]

well it looks like it's not my turbo. The engine was REALLY hard to start after the oil problem showed up. Kind of like it was running on 3 cylinders (and it sounded that way after it finally started). And about 5 mins before the oil started squirting everywhere the engine sounded like it had a little knock, but I figured it was something else benign as how could an engine knock at like 1500 rpms after warming up for the first time in a month. No hard driving or anything. The #2 exhaust port is filled with fresh oil, as is the exhaust mani. That oil could not have come from the turbo, so there's only one other source. Guess I need to do a comp test and hope my cams are still ok.

FUCK.

Any ideas?

[BigVinnie]

I don't know what my name is doin' on that list.. heh

Just for shits and giggles...... It would be nice to see the differences in power between plenum design, and ITB plenum design..... But ehh it was a nice thought since you are runnin' standalone (BIKI VS. Haltech).....
Although the T32 is a step up to what you have.....

[TheTimanator]

Everyone else runs huge intercoolers because they either think they need one that big or just like how it looks more than functionality.
Why is it that all the FMIC kits have such larger intercoolers and for instance the HKS type S is only rated for 400hp? I just put mine on and that thing is huge. It makes me nervous :bite: especially driving around without a front bumper :ughd: If I had to go it again, I'd go go custom.

EDIT: I guess it's not your turbo. That could possibly be even worse! Good luck man.

[SpeedMonkeyInc]

Oh no Scooter! That sounds bad. Did you prime the oil before starting?

[spdfreek0o]

did you make the downpipe flange or did you get it somewhere?

[kay_arsen]

wow awsome work two thumbs up man

[nissantuner22]

Wow keep us updated on how the engine is!

[RBS14]

I bought the downpipe flange from ATP turbo.

Turns out the engine is fine. My injectors are dumping an assload of fuel for some reason. Enough fuel to mix with the carbon deposits in the exhaust ports and look (and burn) like oil. So maybe (I hope) both my engine and turbo are fine! I'm gonna figure out what's wrong with my injectors and then put it all back together, put new oil in it (that's not half fuel) and start it up again. We'll see.

[SpeedMonkeyInc]

Good news mang. O-rings maybe?

[NemeGuero]

What injectors are you using? Did I miss that in this thread somewhere?

[RBS14]

IT RUNS!!!! And it's fast as shit (to me)! I can't believe I stayed N/A for so long. haha It was fun but this is incredible! Gonna tune it in the next few days, I'll post up results.

The injectors are 655cc Touge Factory injectors. I pulled a ton of fuel out, put it all back together and it runs great (needs tuning obviously). I guess I didn't realize how much fuel 655cc's is. haha.

Damn...I wish. Hell, I'd just take the ITB setup because turbo seems so far down the line. Well, excluding when I finally get my WRX...

[SpeedMonkeyInc]

Great news! Plus a *little* extra fuel to clean out the insides! hahah

[Sularus]

That is awesome. Keep us updated. Can't wait to see further progress

[NemeGuero]

So what was the problem? Just untuned dumping out 655cc's of fuel?

Congrats either way!! I know it feels good baby.. oooohhh yeeaahh.

KA-T Fo' life! But damn, with ITBs? SEX!

[RBS14]

yeah, just too much fuel. Also when I put the injectors in, somehow all of the (new) lower o-rings got cut and were leaking fuel like crazy. At one point I unplugged all of the injectors and it was still idling blowing an 11:1 afr. So I think that was what did it.

[EchoOfSilence]

Oh, lower o-ring failure is usually due to mis-installation. be careful next time, man!

[NemeGuero]

OMG, FINALLY someone like me! (except I doubt you have an auto :( )

[PoorMans180SX]

Whered you get the flanges for the itb's-to-manifold?

[Dopefish]

I'm still caught between the decision of BikiROM + T25 or MS and ITB's with the hopes of a T28 later on.....

sexy work, I love it!!

[RBS14]

The 0-rings got all cut up because I didn't use any petroleum jelly on them when I installed them. And I've installed injectors multiple times before with jelly, I don't know what I was thinking.

I had the flanges machined here locally. The guy said that if anyone needs any more, let him know. He still has the file he wrote to cut them so I can have him cut another set whenever anyone needs them. If you are serious about a set, pm me.

[wootwoot]

How is working with the haltech? I'm in the market for a standalone right about now and was wondering how you felt about it beside "great". I'm trying to stay away from AEM with its ridiculous price tag and evilness to user friendly. Microtech is pretty nice but I want to be able to do boost control and last time I checked Microtech cannot control that. Motec is my other option but is also very pricey. Basically looking for a user friendly standalone.
How has your experience been so far dealing with it?
What about that radiator too ;)

[the240sxer95]

WOW, i up and leave this forum for a bit and look what happens!

! ka-t + itb's. i should sell my impreza now =\

If thats a 2002+, slide it over here :D

[RBS14]

Wootwoot: I love the Haltech. I had a MegaSquirt before this and have messed with may other systems. I havn't found one that I like better yet. Especially for the price. The Motec software is more flexible with user definable load points and a couple other features, but is it really worth $5k? Not to me. The Haltech is very capable. I'm using it for boost control, fan control, Wideband control, Direct fire ignition, Full Sequential fuel injection, Anti-lag, and might hook up the turbo timer function soon. The software is also great. You can view and edit most of the tables in text format, 2d by load or rpm, and 3d. If nothing else, it's a great insurance policy for your motor. I see all these people dumping thousands and thousands of $$ into crazy engines then get a rom tune or safc. Alright, my novel is long enough. As you can tell, I love my E8.

[wootwoot]

What dealer do you recommend to purchase one? I'm picking up a 2nd gen rx7 and engine managment is obviously critical to its survival =)
Hm...ITB's on that?....
Cant wait to see some dyno's for your baby and some drag times. I applaud your ingenuity greatly!!

[RBS14]

I'd recommend Speed Alliance. Talk with Warren. For a Rotary, E8's are perfect.

[EchoOfSilence]

ALS?..... you bastard.

biki not good enough, huh? Haltech must be great. How's the learning curve?

[papa]

looking good..must be fun

[RBS14]

Haltech was very easy to pick up. Different format than I was used to from MS, but that's because the haltech software rocks the socks. Street tuning was really easy when it was n/a because it climbed throug the rpms slower. But now with the turbo I'll look at the afr output and the split second it takes me to look at the rpm gauge next to it I'm already a couple thousand rpms higher. So I need to get it on the dyno. Which is a good thing because tomorrow it's going on the dyno and we're gonna tune it!

[drift freaq]

Very cool Scott, congrats on one of the most original setups. Let us know what kinda ponies and torque that baby is putting out.

[NemeGuero]

You make me want ITBs....

[alexchanman]

this setup is so crazy, i thought ITB's by themselves were hardcore but with a turbo!?!?!?!?! you are the mad scientist among us zilvians.

[slideways2004]

this is the kind of build i want to do, but know nothing about itb set-ups

[junkilo]

That's what I was wondering too, but I would think he has plenty of airflow the regular way (through the front bumper).

electric fans and a well connected shroud is all you really need
unless hes going to pound it hard and long at the track.

[NemeGuero]

unless hes going to pound it hard and long at the track.

How else would he pound it?

You see how he's hung..

[BigVinnie]

How else would he pound it?

You see how he's hung..

LOL you funny mutha fucka!!!!

[RBS14]

hahaha you guys are a riot.

Of course I'm going to flog it at the track. This is a track car.

[RBS14]

Went to do some tuning, get the car all strapped down, go to do a baseline and the clutch slips. BAD. We tried a couple different load ramps and gears on the dyno but nothing worked. We were trying to just get a baseline pull since the car was up there, but the clutch wasn't having it. So no tuning for me. I'm going to try and get another clutch in it by this time next week and tune it next saturday.

[Nachtmensch]

damn that sucks about the clutch. i want to see some numbers!

[Dousan_PG]

haha fucking scott
fix your pos
seriously
my clutch went out
thats what every flaker says
do u even have a car anymore?

haha aj/k
oh well was lookikng forward to hangingout this weekend. oh wells. :(

[wootwoot]

well...I have an SR Fiadanza aluminium flywheel and SPEC 6 puck that are both in good shape. Under 10 thousand miles (around 6k)
Let me know if you're interested

[RBS14]

Aaron, I'm really bummed too. I wanted to hang out with everyone as much as I wanted to drive. Now I get to do neither. bummer.

I think I'm gonna get the RPS.

[NemeGuero]

You'll get it fixed.. and then you'll have your fun.
With power comes patience.. hahaha

I have one of the "good" discs. One of the lower rated 6 pucks isnt very durable, it dusts under abuse which in turn gets hot and glases the friction surfaces. No good! I think the combo I have is good for 395 footpounds? I just have no use for it anymore =D
Sorry for going off subject :cry: :cry:

[rossfashow]

dude thats so hott! made me jizz my pants multiple times throught my time reading this entire thread. I plan on doing it to my sr but the only thing is that I dont know if those gsxr tb's will go along with my s13 sr intake mani. time to do more searching. lmk if you guys know about how it'll fit onto the sr. and for the standalone what do you guys think of the apexi pfc?

[sLiDewAys]

scott your killing me, i think im gonna pick up another ca and s13 n itb it. OR NOT haha. everything looks ill man good work. mind helping me with the rb30 itb project?

[Lordrandall]

That is a nice setup dude. The ITB fab work looks great!

:)

[RBS14]

thanks for the compliments guys. I'll hopefully have a dyno sheet up on June 3rd. That's when I go back in to tune it with the new clutch.

[S14DB]

thanks for the compliments guys. I'll hopefully have a dyno sheet up on June 3rd. That's when I go back in to tune it with the new clutch.
Yea! I'm impressed with the improvements you have made since the last NA update. I can't wait to see the dyno curve.

[RBS14]

Went and did some tuning this afternoon. This was our first baseline on the 7psi spring in the wastegate. As you can see there are a LOT of improvements to be made. We got through all the vacuum parts of the maps and will do boost tomorrow or thursday.

Referenced against the fully tuned N/A setup. haha

http://i7.photobucket.com/albums/y263/scooters142/Dyno%20Sheets/turbopics056.jpg

I'll make sure to post up the fully tuned dyno sheet in a day or two.

[BigVinnie]

Holly shizzle smithers look at that torque band!!!!!!!!
Hey Scott why didn't you run the graph longer? It looks like the KA was making a significant amount of high end power. It wasn't dropping off as significant as the NA setup...
Can we call this the SR killer or what...LOL Pretty bad ass for 7PSI, never really seen thatkind of power achieved yet...Much props...

[Neejay]

Damn, nice numbers man...cant wait to see it fully tuned/perfect.

[RBS14]

yeah Vinnie, I didn't do the pulls. Just the tuning. The guy who owns the shop was doing the pulls and going off the tach in the dash which reads high. I'm gonna do the pulls tomorrow or thursday and take it to the 7200 redline I have set.

[alexchanman]

all that on 7psi, wow, just wow.

[CKAMC]

So this is what it looks like when you do a KAT the right way...hahaha

Remember guys a KA isnt ment to see 7k too much.. infact past 7.5 is getting kind of scary for a KA with those beefy rods.

scooter: if and when you rebuild the stock internals with lighter materical you may be able to see 8k or 7.7. Either way great job scooter!!!

[nissantuner22]

Great numbers! Congrats!

[mrmephistopheles]

That's some hot shit right there.

[BigVinnie]

I think it would be a good time to get those internals done!!!!
Hell if you can't get the NISMO crank, a scraper, windage tray, and knife edged crank should get the job done....
Just for shits and giggles a stock SR at 7PSI.....Peak power on the sr 5800RPM, compared to yours???? I dunno it just keeps going...... Then again a stock T25 and 370cc injection won't make that much power on the sr anyways... Hey lets start placing bets, I say Scott will make 400WHP at 18PSI!!!!!!

250whp is not bad at all for 7psi.

But wait.

It gets better.

Scooter, tell them your A/Fs!

[mrmephistopheles]

250whp is not bad at all for 7psi.


7psi from T25 != 7psi from GT32.

[S14DB]

7psi from T25 != 7psi from GT32.
I thinks that's what he's trying to say. :hsdance:

[BigVinnie]

7psi from T25 != 7psi from GT32.

Won't a T25 run hotter than a GT32? Besides I was trying to make injection included as well 370cc defenitely won't make those kind of numbers...
I guess I am missing something with that exclamation point.

[REDSH!FT]

!= means not = to

[wootwoot]

I usually use these for greater or less than < > :keke:

Great fun I bet. The torque will only get better with the higher boost pressures. Wait until you are in the turbos efficency range =)

lame

and by lame i mean coolest thing i have seen in a while, keep up the work on that beast!

Hey lets start placing bets, I say Scott will make 400WHP at 18PSI!!!!!!


he'll probably make more than 400 at 18psi, remember that Ivan from PhatKA-T made 404hp and 409tq @16 psi using that same turbo, and that was on a stock intake manifold. I think that with itb's and proper tunning he'll probably make 400 at like 14.5-15 psi

[RBS14]

Vinnie, you know the comment on the last page about doing the internals, well yeah.

Went back today to finish tuning. Just about had fuel all worked out, turned on the Haltech boost control (which is fucking sweet!) and then we hear some gnarly snapping/weird noises after one of the pulls on decel. #1 cylinder comp tests out at 90psi. So it looks like the ring lands blew on #1. Don't know why, we were only running about 8psi and we didn't boost spike, detonate, or go lean. Everything thing was great. Made a little over 270hp too. Hadn't even gotten into ignition tuning. haha it's gonna make a LOT of power. Had to do 4th gear pulls because it was spinning the tires in 3rd. I'll post up the sheet sometime soon. So now I get to build a motor. yay. Right in the middle of event season. Oh wells. What's another 3 months, eh?

But on the up side I'm just going to skip the whole 10psi tuning thing when I get it back together. 1.5bar here I come!

[EchoOfSilence]

Oh man, sounds like this project is getting even crazier

[Dousan_PG]

kick ass scooter
rebulid it
it sucks
haha im lvig proof
i just want to drive
im sure u are feeling that way too!
think long term!

[NemeGuero]

1.5 bar... you nutty fuck you.

[RBS14]

yeah that's the worst part is that all I want from this car is to drive it. I want to stop spending money and time and drive. But you gotta pay to play.

[McRussellPants]

That sucks to hear man.

I'd look into that intake manifold over feeding the number 1 cylinder. The way you have it setup doesn't look too hot IMO.

If I were you Id cut along the base and add a 1-1.5in angled spacer or something along those lines. In the pics it looks like the inlet is actually blowing on to the #1 velocity stack at a 90 degree angle with the stack protruding into the flow, which would suck balls for proper air distribution...


But I'm heading down the same super response tune path you are, GTiR Turbo, GTiR ITBs, V-mount, Lightweight Driveline, 256s, and all the tuning/bolton goodies to make it work right... I need to start rounding up parts.

[NemeGuero]

yeah that's the worst part is that all I want from this car is to drive it. I want to stop spending money and time and drive. But you gotta pay to play.

I know EXACTLY what you mean...

[ayuaddict]

:werd: its like being married and never getting to have sex with your wife. but you keep spending money on her.......

[SpeedMonkeyInc]

I'd look into that intake manifold over feeding the number 1 cylinder.

Thats interesting. I thought the manifold would pressurize and and be pretty even? It makes sense though if one runner is getting force fed air like that, it would be running lean.

[RBS14]

I designed the manifold like that for a reason. You want the air flow to get broken up (so to speak) and allow all of the plenum to pressurize before any of the runners are fed any air. That way they all get the same amount of air at the same tim. Either way we'll find out because when it's all back together we're gonna test the AFR in each runner simultaneously at a few different loads and rpms to see how far off from eachother they are. Then I can do individual cylinder trims in the Haltech to fix it. We'll see.

[daver903]

why not buy a stock replacement for the motor while you build the other one? half ass tune the stock replacement and you are good to go.:2f2f:

[RBS14]

because I can either afford to build a motor or drift. One or the other. So I'm going to do the one now, that will allow me to do the other later. Man I wish I had a money tree.

[NemeGuero]

Lets plant one...

Actually Scott I looked at your plenum again and there are some problems. I believe what McRusselPant's is trying to tell you is that most air density will feed to cylinder 1. Using a plenum design with a straight through plenum causes starvation to cylinders furthest from cylinder 1, cylinder one when it gets overlap at higher RPM will always take in more air than the furthest cylinder.
In order to maintain a stable more accurate flow pattern the plenum should use a cone shape design not a strait through design. This basically means that air pressure will become more stable as all 4 cylinders attempt overlap at higher RPM. Either go with a cone shape plenum, or use a straight through that is literally three times the size that you already have.

Ivans is a perfect example of a cone shape plenum using more square volume at the begining of the plenum, and less towards the end. This will reduce cylinder 1 from consuming more air at higher RPM during overlap and scavaging.
http://i27.photobucket.com/albums/c166/BigVinnie/Ivansplenum.jpg

On another note you won't need fancy forged pistons. Altima/Exterra/frontier 1998 and above pistons use thicker ringlands, and are more suitable for boost with a CR in the 240sx engine at 9.2:1. You will need forged rods to make over 400WHP though it will startto get risky high reving with that long rod/stroke ratio.

[hitman]

he doesnt rev high
he doesnt need rods
usually on a boosted motor number 4 gets more air
and where is the naked pics!

[BigVinnie]

Actually past 7000RPM is high rev for a KA, he want's to take it to 7200RPM with no drop off in power.
He does need rods he is using a GT32 and injectors that can easily make him 600WHP....
With what proof do you have that number 4 gets more air?
Blah!!!!!!! Not worth my time to argue in Scotts thread....

[ranisron]

Vinnie, As far as I remember, out of all the second gen altima (98-01), 00 piston and rings are your best friend. Some of the DET guys on altimas.net were boosting pretty nicely on the 00 engine. Stay away from 98/99/01.

Best of luck Scott. Get the build going and we will be waiting patiently for some awesome results.

Yeah thats it, I'm not a fluid dynamics major so I can't get into the details of whats going on, but RBS14's manifold has broken every "rule" of intake manifolds I've seen.

I know you did it the way you did for spool time but a larger shaped plenum with an angled or shaped tank would be much better.

Boosted motors #4 Gets more? Not on the SR, the SR overfeeds #3... and so does the MR2. with how small his plenum and how the velocity stacks are blocking air / causing turbulence its very unlikely that the #4 is being overfeed and highly likely the #1 is getting alot of air, granted the ITBs may be helping smooth things out.

[BigVinnie]

From 1998 on (excluding 1998 240sx) Nissan produced only one piston for both the Altima and Frontier/Xterra. This piston has the difference in ring assortment i mentioned above, as well as a very minute increase in the piston dish volume (I forgot about this in earlier post but difference is miniscule). This lowers the compression slightly from 9.5:1 (98 and earlier 240sx, altima) to 9.2:1

The rings are not interchangable between pre 98 pistons and 98+ pistons. .25mm difference in thickness for both compression rings and .3mm thickness difference in total oil ring. Also the oil ring depth is different, 3 different depths changes starting in the 95-97 altima (although these used earlier type compression rings).

I am well aware of all KA24DE differences in casting and components. There are actually 7 different KA24DE cylinder head castings including those cast in japan, mexico, and USA. Some are only minor differences.

As far as pistons, with sohc and dohc combined, there is 8 different oem offered pistons.


Gabe will sell you the pistons with an overbore if needed 98-2001 pistons are all on the same production.
My brain is a sponge when it comes to KA information I memorize quotes, as well as information from the FSM, and tech info that I have done myself.

[ranisron]

Vinnie,

Thanks for the info :angel:

[RBS14]

About the plenum design. So you're saying with a full radius stack that would deflect airflow above or below its opening upon entry into the plenum would over feed #1 but a design that shot air directly into cylinder #'s 1 and 2 wouldn't over feed them? what kind of sense does that make? The plenum doesn't taper for a good reason, because I want all of the stacks to have the same area of air above them and same proxemity to any walls so they can all get the same amount of air. If you just have runners going off the bottom of the plenum floor to the engine without any velocity stacks you need to reduce the possible amount of air each successive cylinder is getting because you will get losses on each cylinder as the air travels back. This is not the case with velocity stacks sitting above the floor, in the air stream. At any rate, we're going to try doing this with the stock motor again, and trim #1 10% (more fuel) and see what happens.

[BigVinnie]

I didn't say that.

This is not the case with velocity stacks sitting above the floor

Whats wrong with a tapered plenum? Tapered plenums (I call em cone shape) are made to evenly distribute the air flow to feed each cylinder. When you are running low boost or are spooling, tapered plenums work most effectively to allowing the engine to take what it need's until enough pressure builds in the system. Tapered plenums allow the molecules to spread evenly along plenum even during the point in time in which they compress in the plenum chamber during boost. You do need to realize though as pressure builds so does the effect of valve overlap, and scavaging.Increasing boost pressure only increase the momentum of the intake charge allowing for alot of o2 to pass right through past the intake and exhaust valves. So there really isn't 8PSI of boost pressure in the plenum, even if you run boost at 8PSI, air is constantly moving it's way through the cylinder and through the exhaust.
In your case it almost sounds as if you wanted to apply constant pressure to your plenum. That isn't the case as there is spool time to where the engine can infact consume more air than what is given from the turbo at low spool.
Since the dynamic of pressure is to look for the nearest closest exit (if you built a hallway and were trapped what door would you go through first) hopefully an easy analogy to understand.
Much appoligies Scott if you think I am trying to offend you, I only want to help in better your project.....

[EchoOfSilence]

really? cuz by the look of it, it seems like most of the air'll be forced unto cylinder 1 with that design.

hell, I don't know shit yet. I'm pretty sure i'll be wrong :o haha

[Johny5]

Much appoligies Scott if you think I am trying to offend you, I only want to help in better your project.....

.


I don't think the plenum is big enough to get air to the number #4... and with the way the manifold inlet comes in I could see it overfeeding #1.


Whatever, we'll find out when you run an A/F on each cylinder.

-McRussellPants

[NemeGuero]

Maybe you can flow test the manifold and see?
I know there's a software that does it, we use it for our FSAE car.

Scott, if you want to send me dimesions and stuff of your manifold I can see if we can put it up on the computer at school...

[RBS14]

Vinnie, I may have come off a little harsh there. I know you're trying to help. some air escapes through the exhaust via overlap, but not much. The reason overlap is present is to actually create more of a pressure differential between the intake manifold and the cylinder, thus sucking in more air, increasing VE a bit. Only a very small amount of air escapes into the exhaust. You do actually have a positive pressue in the manifold. That's precisely what boost is. Unless you get the taper in the plenum exactly right, you are going to create a different VE in every cylinder. The only way to get it correct would be extensive design via fluid dynamics and testing. The next best way I can see is expose all of the cylinders to as close as possible to the same conditions. The best way to do this is to have the air flow come in exactly 90* to the runner direction so it can equalize and distribute evenly. Especially if you have a mechanism that helps to reduce losses to each cylinder as the air feeds in.

Who knows. It's all shit none of us really fully understand anyways. haha

I'm just going to throw another stock motor in it, trim #1 10% (in case you guys are right and it is going lean) and try again.

[BigVinnie]

Vinnie, I may have come off a little harsh there. I know you're trying to help.


It's all good man.
Really if it was me doing an ITB set up I would'nt even do a plenum design. I would of just made 4 equal length runners into a 4-1 design to seperate equal boost pressure to each runner/ITB.. It would pretty much look like a smaller version of a 4-1 exhaust header strapped to the intake/ITB's.....
If you don't get the richness down on cylinder 1, I would gladly help you weld a different style manifold.
I've been reading a book on fluid dynamics and plenum design, there are some pretty crazy contraptions you can make for your ITB setup, your not just bound to plenums.
No need to apoligize Scott everyone thinks I'm an asshole in the forums till they meet me in person, no offence taken. Keep up the excellent work.

YES!
That's exactly what I was thinking, but I couldn't put it on in words well enough to actually post it. I agree, Vin.

[RBS14]

Except with that design you have no extra volume of air when you snap the throttle wide open to fill the runners. You just get a void where the engine can't get enough air. That's one of the main reasons why we have plenums. The real trick is to make a plenum that is just big enough to supply the engine with enough air in that situation, but not so big that it induces a bit of lag or slugishness.

[nissantuner22]

Right, take a look at ARC's line of N/A performance parts. Their induction tubes have huge pockets for air, to increase throttle response in the situation RBS14 describes.

[wootwoot]

Could you link to that part you are speaking of Nissantuner?

[infinitexsound]

nice scooter at only 7 psi, i dont think scooter is doing anything wrong with his intake manifold setup at all.. granted u want one of those slanted design .. for more effective air flow... but i've seen a gt3 car run a squared shaped one.... with ITB.... im guessin u bought one of those ross racing kits they sell....

honestly the air flow u would want to look at is how it connect from the TB to the HEAD... if u notice inside the KA head how its curved... youd want a direct airflow that continues with good flow too the intake port.. scooter did this well by using the stock intake half of the OEM mani.... most guys just run like a straight setup to the intake port... that to me is not connecting well to the intake port.. and is not giving good flow... THINK CURVED inside the KA head.. and youll see what im trying to say....

SCOOTER GOOD JOB MAN @ 7psi... WOW

AND VINNIE i like u man... u know what ur talkin about...and have to balls to say whats on ur mind.... WHATS REALLY REAL? and WHAT IT DONT DO?

[RBS14]

Been gone for a while. I got a new motor put in like 2 months ago and the oil seal went to hell when I tried putting my aluminum crank pulley on. The nub that the pulley lines up with dislodged and pushed into the seal. Just my luck. I was so sick of my car I took it to a buddy's place, and he let me keep the car in his garage in San Diego for the summer while I came back up to Norcal for the summer. I'm going to go back down to San Diego in 2 weeks for school and I'm gonna throw a new oil seal in it. It will then meet one of two fates:

1. I sell it.
2. I drive it back up to norcal and put it in my garage here and forget about it for a LONG time.

Luckily I've got a couple weeks to decide.

Just thought I'd update you curious folk.

[SpeedMonkeyInc]

Sounds like me Scooter. I am about to park my S14 and leave it in storage for a few years. I am sick of fixing it right now, I need to get other things in my life prioritized.
Good luck with whatever you decide!

[Mr. Camshaft]

I think what Vinnie was trying to say was that while the area above each TB may be the same, once the motor gets running, the air density over each changes. With that 90 degree setup for all four intakes, each progressive intake takes in less air. The difference may not be huge, but it's still there. You end up with a pressure/density gradient, not the equal distribution you were looking for.

[ramblux]

Damn Scott, sorry to hear about your luck with that engine. And sorry I didn't reply back to your PM to me on that "other" site -- I got a bunch of PMs that day and still haven't gotten back to all of them. I appreciate all the help!


And if you do decide to sell her (and I hope you don't), let me know how much you might be wanting for it.

And let's please get that thing shot when you're ready!

[articdragon192]

Hey, I couldnt PM you cause your inbox is full, but where did you get the velocity stacks you used on the plenum? I just got my ITBs but I need veolicty stacks so that I can have someone fabricate me a plenum for it.

[RBS14]

Mike, we'll definately shoot it before I do anything with it. No prob bro!

Stacks came from Velocity of Sound. Google it and the site will come up.

[P4rD0nM3]

RBS14 Pimp my ride please. I just added this to my bookmarks. Rofl. Damn, do you fabricate them all by yourself?

[HKSdrift3r]

how do you know it wasn't detonating? You cant always hear it without a detection device and even if you can hear it without one then that means you got some serious detonation.

Welcome to last year.

Scooter are you alive anymore!?

[RBS14]

hahaha yeah I'm still alive. been busy with everything but cars. haha

I'm actually getting stoked on my car again.

I got it running again a couple weeks ago. Made me realize how much I didn't want to sell it. I love that thing regardless of how much time, grief and money ONE FUCKING INJECTOR costs me. When I got it running again with a new block in there it sounded like it was running on 3 cylinders. Pulled off the #1 injector clip and nothing happened. Pulled off #2 and it started sputtering and running like shit. Swapped #1 and 2 injector clips to make sure it wasn't bad wiring. Sure enough, my #1 injector went static. Needless to say don't ever buy venom (touge factory) injectors. I'd heard bad shit about venom in the past, and this is proof enough for me.

Good news though is that I'm finally going to build the engine I've always wanted. N/A style. But still with boost.

In the mean time i'm probably just going to throw some different pistons in a stock block so I can run a bar of boost and feel safe.

Sorry for the novel, just thought I'd share some of my thoughts and give a little update.

PS i got delphi for the next project. :D

[CKAMC]

So.... whats new :D ?

[bardabe]

I may not be a rocket scientist but The GTR has ITB and the manifold dosent have the "Cone" design. and IM sur enissan owuld not esign somethign tat woudl starve cyliner 6 and pig out cylinder 1.

[freeman]

good work, looks like is going to be a good one

[gunluvS14]

please don't stab me. I know i shouldn't dig this thread back out, but i would love to know the update dude

[CKAMC]

Yeah what happened to scooter? Did I miss the funeral or somethin?

[Dousan_PG]

i thought the engine popped?
scooter doesnt even come to the track anymore
too cool for school!

[RBS14]

hahaha

I did dissappear for a while. Been balls deep in school. I actually haven't been to the track with the turbo setup yet because I've had a series of mechanicals. Blew my original block on the dyno, #1 injector went static. (It would have been a damn strong motor had the injector kept working. The motor lasted for 20 minutes of load tuning and pulls before it finally blew.) Then an axel. Then blew a jb weld plug out of the ITB's from the vibration and boost pressure. And the motor I've got in there now is Dousan's old one from his fastback! hahaha 230k + miles. So it can't last too long with boost.

So as a result of this I'm throwing all the turbo stuff in a box for a while. I'm super bummed but I can't afford that shit right now. N/A for a while so I can actually make some events this summer! The new N/A setup will be improved over my old one so should be slightly more potent hopefully. Still slow compared to turbo, but oh wells.

I'll post up new pics when I finish my new high rise 4-1 header and get a new dyno graph for you guys.

[ms!3]

you dont need that turbo, stay n/a. what ever happened to n/a ka monsters only? oh and post up a sound clip if you could with the new setup. itll sound like sex, lol.

[240trainee]

Lol, n/a monsters

Yea, run that shit n/a for a while, but you know you have gotten bitten by the boost bug. Just need the funds to build a bullet proof block and your be good to go.

Details on NA KA.

I went through the same stuff (though not as many mechanical failures) and now I'm NA KA too

[Dousan_PG]

holy shit
my old motor?
MY OLD MOTOR
get serious
haha
i didntknow that thing was still around too
THATS NUTS! hSAHAHAHAHA
that was a great motor though, i must say!! :) GOOD LUCK

[RBS14]

HAHAHAH Matt best pic in this thread by far!!! And the hair on my chest is in the shape of a cockenheimer.

Yes Aaron, your OLD motor. I love it. Got it from Danny. It's the cleanest KA i've ever seen. Still stock rtv everywhere and no leaks whatsoever. Thanks for the well wishes, I'll need them! I'll see you at all star bash!

Motor is still stock block (save for JWT cams). But I've got another set of full radius velocity stacks like the ones in my plenum, and I'm building a true equal length 4-1 high rise header. Also got a super light weight, small diameter twinplate that makes it rev way quicker than it used to. So harsh I'll prolly blow through trannies with 160hp haha. And soon an aluminum driveshaft. Nothing big, just hopefully something that's fun enough to drown out the sounds of my turbo calling to me.

[NemeGuero]

I hear those calls too..

[drift-it]

that setup sounds legit scooter. i bet itll be fun as fuck. hollar if you need an extra hand/wiener

[wannabe_drifter]

What is that twin plate you are talking about ???
gotta be nice to have the engine rev quickly

[Nikeboy355]

[wannabe_drifter]

hahaa ... should have thought about that ... sorry !!

[RBS14]

Matt, Katrina says your drawing is an accurate depiction of me. haha.

I'll take the weiner.

[RBS14]

[DoriftoSlut]

You and me both Scooter! All Star Bash or BUST!!!

Looks good. NA again? How long will that last?

[Ian]

hopefully longer than turbo did :hehe

[cronux]

hey, scooter, what exactly are you doing for ingnition timing, because you used to be using the custom triggerwheel on the pulley with the system from a escort right? and this doenst look like that one, and if i remember, you sold that.. so what are you running up now?

[sonnysmr2]

haltech, from what i remember

[cronux]

well i know its managed by the haltech e8, but you were running a trigger wheel with a coil, and im too dumb to see what you have now.

[RBS14]

I used to use EDIS.

Now I use LS1 coils run by the Haltech. The Haltech gets the signal from the stock dizzy. Very easy to wire (4 wires from/to dizzy).

[cronux]

huh... thats very interesting/cool. so it gets the timing signal from the distributor, sent to the haltech, then haltech sends a signal to the coil, which then runs to the plugs right? and im assuming that MS can't take that kind of system, right?

[gunluvS14]

wow, in 3 weeks i missed out a lot already. I didn't knwo u went back to KA.
That header is a piece of art man, u got the merge collector from burn stainless right? great job
i can't wait to see dyno graph again, and how about some video clip too?
the thing is so sexy :)

btw, where can I buy KA exhaust flange? so i can mock up some chit too when i want to.

[ms!3]

possibly a write up for the haltech mabey? just a suggestion but painting your valve cover and polishing the header would make your bay really nice. looking good bro, im looking forward to updates. n/a ka ftw.

[cronux]

looking "nice"??!? jared.. you are crazy. that isnt nice. its amazing. already. like, its my background right now, and i worship it. haha. n/a ka is simply status.

[skylinekin]

I wanna hear this SO bad!!! Must sound awesome at wot.

[ispypsi]

[bardabe]

Video! Now! Now I Demand It!

[sideview_180sx]
