Project Twin Turbo KA in a S14: Part I

[heinekenns]

I have not had a chance to do much with the other project (Project VG30DE(TT) in a S14: Part I (http://www.zilvia.net/f/showthread.php?t=31379) ) so I figured I would use some of the left over parts and make something with the daily driver. I have no illusions about how practical this setup is - it is not an ultimate power project - it is not an attempt to win NOPI - I like fabricating and this seemed a little more challenging than the last single turbo setup built. We will all have to wait and see how well it really does work. Here is the setup and pics:
Stock KA w/120k
d21 flywheel with 300zx ACT clutch
DSM 450cc Z32 Maf Z32TT fuel pump
Greddy E-manage
4 DSM IC's
2x 90-96 300zx turbos - some call them t25-2's others call them T22's. In any case, they are small. My rational is that if 1.5 liters spooled them at one time, 1.2 liters can try and spool these. I have tied runners 1 and 4 togethor and runners 2 and 3 togethor. I did this to minimize irregulariies in the exhuast pulses because of the firing order - although it probably doesnt matter that much and I could have just tied 1 and 2 and 3 and 4 to make my life alot simpler. Let me know what you think. This project is going alot faster than the vg project

cool if you get it to work,,looks like those IC's are gonna take up some space

[element240]

GOOD LORD!!!!! :eek2:
4 intercoolers??????? :aw: isn't that gonna cause a bit of turbo lag?

glad to see your project is coming along , post vids when you're done!!

[240Stilo]

Why not make the manifold go into one turbo and have the exhaust from that turbo feed into the second turbo?

[D1drifter]

how much power are you planning on putting out on this setup?

[drift freaq]

give the man props and so cool to see some one doing the D21 flywheel mod after T.Y. first proposed it and I took up the challenge and did it on my old low mileaage 91 r.i.p. I don't know if anyone did after I did, god old Fresh Alloy days. heh. Anyways congrats and hope you lightened that D21 flywheel. Lightened its a really sweet setup for the KA.

[ryan hagen]

whats the d21 fly wheel? ive been wondering about a vg clutch on a ka fly wheel, i know they can do it with sr's

[andrave]

prolly isn't gonna put down hella high numbers, 440's would limit him. those turbos are kindy poopy for a KA, but they are tiny, and in your case, free.... the IC thing is outrageous, is that even gonna fit behind the bumper?. The manifold looks good though, I might modify your design for mine now that I see it could work. I was gonna go just 12 34 for simplicity.
anyway check my page for updates on my project, we should get them done and go race.

[skatanic28]

more work on the vg is needed ;)
looks pretty nice though

[drift freaq]

the D21 flywheel is a KA24e flywheel out of a Hardbody pickup. the clutch surface area is 240mm vs 225mm for the standard 240sx ka flywheel. more surface area equals more clamping power for a higher torque horsepower situation. there are a number of different clutch options availible in 240mm and ACT and several other manufactures address it.

[240Driver39]

nice, cant wait to get a ride in it :rawk: ...that intercooler setup looks huge haha, manifold looks very good tho...when u project being done?

[mellojoe]

interesting concept....

very interesting...

[019]

you're a post whore! this project sucks!

on a more serious note... the manifold is definitely awesome and everything fits really well. nick failed to mention that the ic piping is not going to be the conventional right to left flowing, but from top to bottom, which should help the piping. lots of cutting required to make it all work tho...

this man's a damn machine! works non stop for like 8 hrs. can't wait till it gets finished. it ought to be very interesting.

[andrave]

wait a min, you know this guy and have seen the car, you live in blacksburg.
I have talked to him on aol, I'm in Princeton, WV, just like 1.5 hours above blacksburg.
If he lives down there I'll come check that shit out.
aim is aandrave
we actually could get two TT ka's together....and he could help me weld my manifold!

[240Driver39]

haha, u should roll down sometime...usually good times around b-burg.

[180fan]

wouldnt it take forever for those turbo's to spool? I mean you're driving a turbo via 2 cylinders.

[Bbandit]

its 2 "small" turbos

[phrozen]

those turbos should spool up fine. they spool up really fast on a z32 with 1.5 liters per turbo opposed to 1.2 liters per turbo on a ka

[CustomS14A]

http://www.egarrett.com/products/gt_15_25.jsp



The GT 15's application range is for 1.3 to 1.6 liter (60-80 bhp) diesel engines and 1.0 to 1.4 liter (85-120 bhp) gasoline engines. The compact packaging makes the GT family ideally suited for twin turbo applications on V-block engines. The GT 25, at the high end of the range, can be configured to match gasoline engine ratings up to 210 hp. The GT 17, GT 20, and GT 22 fill in the flow ranges between the GT 15 and GT 25.

[andrave]

ok, what the hell are you talking about?

[oojpeeoo]

wow i would like to see this when its done

[PARAD0X]

wouldn't a standard front mount with cutom piping and custom endtanks be more efficient?

[andrave]

you just dont get it...
I think I do.
if he could order it from a catalog, then
1) you could order it too. so could I. and other people will. And how boring is that?
2) he would be paying for someone else's time to put it together, when he could himself.
3) for me anyway, the whole point of working on the car is the long process of saving parts, searching junkyards for hard to find stuff, scouring ebay, spending a long night in the basement grinding, drilling, welding, etc... thats what is fun, is working on it. No artists paints a picture to stare at the results, its the creative process that makes it fun. And what makes it unique.

[heinekenns]

How much power is this going to make?
- Hard to say honestly - I will try to tune for 250whp - yeah, that sounds like a goal. I really dont know what to expect from this setup.

drift freaq explained the clutch setup perfectly..... and heheh, I didnt lighten the flywheel before hand. I takes a few minutes to rev the engine at 24 lbs. Finding a lighter alternative is on my list of things to do.

Paradox - in hind sight, a premade IC would have made my life alot simpler. Especially since I am having such a hard time getting the end tanks to line up with the edge of the cores. Ukanns right about it being top to bottom and not side to side like normal. It resembles a mustang IC more.

...andrave knows what its about with #3

[mutkung]

look like really cool project. Never thought it was possible but I don't know much about fabricating stuff anyway :duh: .
Hope every thing go well, and good luck.

[Andrew Bohan]

does firing order come into play when deciding which cylinders go to which mani? seems to me that alternating manis would be the way to go, but i dunno
anyone?

[skatanic28]

anyone?
i think thats the right setup if firing order really matters. but each cylinder is firing between 15 and 50 times a second i believe, i really cant see it mattering much either way, maybe just a bit smoother. more pics when you get the piping ran please, that should be fun for ya :)

[AceInHole]

those turbos should spool up fine. they spool up really fast on a z32 with 1.5 liters per turbo opposed to 1.2 liters per turbo on a ka
Also note that the KA comes with higher stock static compression. Should make things about equal.

[019]

wait a min, you know this guy and have seen the car, you live in blacksburg.

yes, nick is in blacksburg as well. we have our little 240 community here. and speaking of princeton, i was at mercer county today for autox. didn't know you were that close, haha.

[andrave]

what autocross? godamnit.....
all I did was sit on my ass.....
well shit 304 384 5763 call me sometime, we could hang out. every fri/sat night when the weather is good hundreds of cars cruise princeton, there are some cool guys up there, TT supras, 300zx, wrx, blah blah.

oh and I'm gone the 15th, moving back upstate.

[bkfill]

hows the project going :love:

[Ghettokracker71]

Time for an UPDATE!!!!!!!!!!!!!!!!!!! Wow,thats a hella awsome project...

[brianglawson]

hey andrave..im 30 minutes away from ya man....i go up to the strip every once in a while:) ever talked to the TT supra dude, its a white limited edition with a kit, and a trd Carbon hood....but the heart is the main props, hks is adorned in the engine bay:) gotta love it:)

[bkfill]

whats wrong with 12 then 34?

[Red]

wouldn't a standard front mount with cutom piping and custom endtanks be more efficient?

I think is was in the Corky Bell turbo book that I read that top to bottem intercoolers are better at having little pressure loss... (Becuse there are more tubes for the air to flow... Most intercoolers are longer then they are tall)

[andrave]

12, 34 is not optimal for the ka firing sequence (1342).

brian- I graduate from concord on saturday, it will be my last weekend in the area. yeah I have talked to that supra guy, he is nice but I don't know how much he knows about cars or driving.
my friend and I were down a while ago, with a yellow evo 8, drew quite a crowd in princeton.

[brianglawson]

say it probably did man.....ever seen the little 4 door dodge dynasty spray painted purple with like gray flames and slammed to the ground....with a fart can on it....its the whole reason to go there.....just to laugh...haha

[KiDyNomiTe]

Good luck. Your like a big kid playing with 2 lego sets that got mixed up :), only time will tell.

[andrave]

legos all stick together. its not quite like that.
I need oil inlets for my turbos to finish my project....
I wonder if they are the same as TT
I also need compressor outlets.
I am sure they are the same, just cant find anyone selling them.

[bkfill]

:mepoke: :blah: what the hell is going on with this project

[phrozen]

hehe a project like this takes time. hes probably speding time working on it. Ic piping and tuning is going to be interesting..

[heinekenns]

...hey, sorry no update yet. I just now finished my last final today so I finally have some time to devote to the project. Between moving my chit to a new house and moving my fiancee's chit, and breaking a rib working out (who breaks a rib on a leg press ?) I have been stacked with work. I think I have all the parts I need; I still need some ss lines and fittings and such, but the big/fun stuff is done. Time to put it all togethor and find a person with a digi cam. The manifold turned out very well; it needs to be cleaned up on the inside with a die grinder. THe intercooler end tanks ended up being a little larger than I wanted them to be, so if I feel they become a problem, I will just use the IC on the 300sx which has no problem filling up large endtanks with copious amounts of air. I will get some pics as soon as I can. Its a slow fun process.

Nick

[HamSupLo]

good to hear! and sry about the rib man, just fab your self a new 1 :)

[RedlineRacer]

You gonna have enough room in that engine bay to do all the piping? Looks like its all going to fit very tight.

[NITECRAWLA]

Hey I Already Have A Manifold Made Up For Twin Turbo Ka24de Its Already Fited I Built It My Self I Have Pictures If Anybody Is Interested In The Manifold Its Actually Up For Sales Or Trade I Had It On My 96 240sx I Had To Move So I Sold My Car Now I Have The Manifold At Home Other Than That Like I Said If Anybody Wants It Drop A Messege And By The Way Great Work I Wanna Se Ur Project Wen Its Done It Was A Pay In The But For Me Too

[Slidin240Wayz]

wow

msglngth

[IGSDann]

Um dude...

You only have to capitalize the first word in the sentence unless it's a name or an I...

Oh and this thread is like 2 years old so... yeah.
