KA-T manifold opinions?

[GoKu]

For those of you who are KAT or not ,Which Manifold would you choose if these were your choice?

log style manifold (i belive JGS)

or

Rev Hard Manifold ?


Im still debating which one has Better runner and airflow ...I like to hear some of you opinions please

I also like the Ebay SSautoChrome Manifold as well but there is no word on those yet ..Thanks in advance for your replies ..

[sxse240]

If I had to do it again, I'd choose the JGS Tools manifold.

My RevHard took a lot of work just to make it fit. The casting tolerances are sloppy as hell. The header stud mounting holes were misaligned by 1/4" at one end, so it wouldn't even go on at first.

After fixing the holes I ended up porting it because the ports on the manifold are round, while KA ports are kinda square. That took a damn long time and was messy as hell and no fun at all. Then there was seperating the runners on the flange to prevent cracking. There's a bunch of of other material to remove from various places, too, if you want to maximize flow.

All in all, it just plain sucks. But I'll be happy when the SS Autochrome manifold (http://www.planb-attack.com/kyle/group-buy.htm) is finally available, because I can just swap it in with no modifications. So, if you gotta have it now, go with JGS Tools, otherwise, wait for the SS manifold.

[Jeff240sx]

I didn't have any of these problems with my revhard. I've had it for nearly 2 years and no cracking/rusting through. But I do like the look on those autochrome manifolds... equal length = more power :) Any word on when those will come out?
-Jeff

[GoKu]

Also , How many of you guys have a deciding factor on the type of material made ?

Rev hard is Cast Iron I belive ..in terms it should be more durable from the heat

JGS? im not sure what type of material this is made of ...

F-max?

SSautochrome is a very nice design but not sure what type of material it is made from ...


I am leaning more towards the SS ...but the Rev Hard seems to be around for awhile now ...I heard Nsport or XS eng Turbo kits for the 240 comes with the Rev hard?

F -max also is a log style type like the JGS ...

More feed back please? thanks for those replies as well ^^ guys..

[fastpace]

I think material is important. I was or still don't know haven't heard from the guy in awhile about making me a custom ka-t manifold. He was going to use stainless steel which is pretty good against heat. He gave me options which were cheaper, but I didn't want to go cheap and in the long run shot myself if anything cracked on the cheap one. But the cost of his manifold was more than 1000 bucks, so I think I am going to wait and see how much the SSautochrome is.

[GoKu]

^^ anyone else?

[Grant]

I don't know if you can still get a hold of this one, this is one of the best I've seen yet. It was made for Chris May's car..

http://www.executivecleancar.com/KAManifold/Info_and_pix.htm

I think Tom Rice still produces it.. not sure..
I wanted to get this one for my car..

another good one would be greddy's but i think those use mitsubishi turbos only.

Ive spoke to Chris a few times and they arent in production anymore....im trying to lean from getting a custom Manifold...To let you guys know my history ...I had BYP made a custom equal length that cost me $900 for my U13 Altima KA24DE(T) ...not less than 2 month ,the car got stolen. So I was out of luck ...

Im pretty much almost done, just keeping my options open now ..thanks guys

[GoKu]

^^come on guys,I know theres more Turbo heads here...

[95Blue240sx]

i actually have a RH manifold, but im still gathering parts. i noticed that the ports are round too. i wasnt too happy when i saw that. but i got a deal on it. hopefully my install will go smooth and and everything gets aligned. but im so broke i cant buy anything for turbo setup. ALL in time, my girlfriend keeps telling me. then i say STFU gimme money!!!

bj

[GoKu]

anyone selling a RH manifold ? :D

[95Blue240sx]

the ss chrome looks awsome, id sell my RH to get that. depending on the material.

This place http://www.full-race.com/ makes them for the SR, and on Fresh Alloy a guy from that company said they will be looking to make some with KA flanges. They are pricey, but they are the best manifolds I've ever seen.

[cdigity]

i've got the jgs log and i works just fine
no fitment problems
and the best part is i got to weld the flanges
exactly where i wanted them

[ryan hagen]

check out the unstable hybrids manifold, its in the links section, go and look at their site under their products, it looks like a combo header/manifold, it looks part like a cast, but its welded too.

[andrave]

I'm using jgs tools tubular style...
log style seems to work well, and if revhard cracks cast is a lot harder to weld than regular steel....
jgs you can make fit no matter what you got, but you do have to weld it up.
revhard doesn't seem to fit very well, especially with larger turbos. master cylinder clearance is tight..

[GoKu]

Do you have pics of the JGS tublar style? I havent seen it before, Also I should note this manifold is going into a U13 KAT (Altima)

[andrave]

go to jgs, its listed there with pics of what the kit includes.

[meme]

if you want a log manifold i would say make your own. even if you get the jgs one you still need to grind and cut an openning for the turbo flange. if you can do that you can pretty much just weld the rest of the pipes up.
but if you are not comfortable with welding then buy a finished manifold.

here is a small write up on making the manifold. http://psijunkies.com/turbomanifold it was half tig welded and half flux core welded. i ran out of gas and was in a rush.

i've listed part numbers if you want to order the pipes from mcmaster.com . here are some more.http://psijunkies.com/240sxengine.html i no longer own this car and turbo kit

here is my next one http://www.imagestation.com/picture/sraid98/p309ad5ba34a4b358ff2d9667707e0fd0/fa038917.jpg

using flux core cause i sold my tig welder.
http://www.imagestation.com/picture/sraid98/p072d9186b92055e65172eba4dbd01386/fa03891d.jpg

i can get you flanges if you need them. should be about $100 for all flanges and pipes. give or take a few bucks.

good luck..

[GoKu]

andrave

When you mention about the tublar style ? are you talking about the JGS elbows that have 90degress and differnt bends ? compare to the log style ? I wish I had pics of the custom equal length I had before on my car , the only thing that compares is the SSautoChrome.. I guess patient is virutue, Most likely with the SS I will have to Thermal coat it and maybe do some adjustments to the flanges like the Rev Hard's

[GoKu]

meme

Dude thats some real proud work that your doing, at least you can say *YOU* acutally build the manifold,its not an easy task for me because Im not experince in welding ..only mechanics , the manifold is looking great.But I couldnt imagine where to start it I was in your shoes, Thus the reason we should have threads about the types of manifold -cost-material-performance-, alot of the feedbacks here will answer alot of newbie question and rasie more opionions,

So far Rev Hard -Cast Iron ,But prone to crack $400
also is it true that Nsport and the XS engineerer use the RH can anyone confrim this?

JGS log style or tublar ...well this is basically the way you want the welding shop to do what you like IE: top mount,side mount ...so on so fourth $150 +

UH ---not really a great feedback here ...more info as we gather along the way ,altho looking at their site ,the welds looks sloppy and alot of silver spray paint $450 shipped

F-Max --well I belive they are selling them for $600?

Turbo Boss manifold -- again not much info or feedbacks yet $800

SSautochrome..AKA OBX racing , well basically Ive seen a few items from them ..welds are decent but the material is stainless steel , up for opionions $400


ECP racing (canada) is also set to release a manifold as well $600? or $800? the site is down so I cant search ,

anyways feel free to add more and feedbacks, altho I am a Hugh Nissan fantiac, My set goal is to knowledge the types of manifold , the cost. More newbies ask the same question @ the alty .net site ..also There is a few issues with the manifolds not bolting up, flanges to be seprate so he can disspate, and also the issue with the Master Brake cylinder. Altho I own a U13 (Altima) Im still running a KAT niether less..

[sxse240]

The ETD Racing manifold (http://www.etdracing.com/ka24.html) is getting very close, it seems. As far as quality goes, I'd put my money on this one.

Interesting....I'll have to keep my eyes open regarding this manifold. Some of their other work looks very nice. I don't know that I'd want to be part of the first batch (incase there are bugs to work out), but the price seem good for what you get.

Equal length runners and some heat coating process.

[Jeff240sx]

So far Rev Hard -Cast Iron ,But prone to crack $400
also is it true that Nsport and the XS engineerer use the RH can anyone confrim this?

CONFIRMED! Unstable is no longer producing their KA manifolds, or at least not for a while. The Chris May manifold is also out of production last I heard.
If you don't like the design of the FMax, that's one thing. If you do, and want it to last, do the smart thing and ceramic coat it. HPC or JetHot both say that if the manifold cracks/rusts through they will replace the piece, provided you sent them a new one in the beginning.
-Jeff

[GoKu]

thanks for the confirm Jeff240sx,

As for the F-Max and JGS , some have mixed opinions about Log style manifolds.
Some have proven much gain with the log style, But I've personally have an equal length before,altho customing is not a very cheap thing.

Im glad SSauto has made one but Since the update on the ETD manifolds, i might lean towards them ,and the price is decent. I just hope theres a way I can Mount it in a U13,

[kaje36]

the SR sscrome mani should be welded to my KA flange on friday. ... still got to cut off that SR flange.. and that turbo flange.... but expect some responce on this on saterday

Mark

[GoKu]

Great to hear kaje36 , thanks for the update.

[AceInHole]

Here's how far I've gone with the SS autochrome SR manifold on a KA:

the only problems are that the SR head is over an inch wider from the centerline since it has a more complex valvetrain, and the KA deck is 40mm higher. I'm extending the runners on my manifold since I'm using a T25 turbo and O2 housing, so that I don't change the positioning of the turbo. It turns out that this isn't the greatest way to save money, but it WOULD place the turbo in nearly the same place the SR's stock turbo is. This means SR intercooler kits should fit (at least using the S13 coldpipe IIRC) and SR downpipes MAY fit. I gave up and I'm having the downpipe custom made.

The option that I think may be more cost effective now, however, is to take a stock cast iron SR manifold, and combine it with a stock S14 KA manifold. A good welder should be able to do it, and both peices should be available cheap enough for the overall project to have a reasonable end cost. My SS autochrome conversion is going to end up costing me 350 just for the manifold, even though a lot of it is because we can't make a definite measure of how long to extend the mani, and so I've gotta pay for shop time to have it done so it fits right (i guess after this it'll be easier for others). The cast iron version should be a lot less as long as you can do some of the prep work....

Finally, since the difference in flanges is over an inch, it WOULD be possible to create an adaptor flange.... that bolts onto the KA head, sticks out an inch, then has an SR flange with studs in it to bolt an SR manifold to. I might see how reasonable something like that would be to make, but it wouldn't happen untill I swapped the project car to a DOHC engine, so basically not anytime soon. If someone else wants to attempt this, that'd be cool :p

As for Kaje's manifold... since he's using a T3 flange, he'll be able to clock the flange outward more to allow the turbo to clear the block, getting around my major headaches quite a bit easier.

[andrave]

cast is not a good metal to weld on though...

[RedlineRacer]

I've talked to honda people about SSautochrome, since they have been making a turbo manifold for those for a long time, and they said they aren't the greatest quality manifolds. They tend to crack fairly easily. But this is just hear say, take with stride.

[AceInHole]

the same goes for the SR manifolds. they crack at the head flange and the collector.

mine is getting rewelded anyways on the KA retrofit, but the guy doing the welding (very good, very experienced) said the welds actually look pretty good on it, and the piping is pretty decent. guess we'll see how it goes.

[AceInHole]

cast is not a good metal to weld on though...

not good but doable, especially if you've got access to a torch and a very powerful TIG welder.

[95Blue240sx]

IMHO if you really want a reliable manifold, you'd have to use 321 stainless steel. this stuff is strong!! garunteed not to crack. i think why 240 people complain about cracking is because we dont want to pay the $$ for the right material.

but dont take this to the heart. i mean im going to be using a revhard.

[sykikchimp]

I just think all the attention the KA is getting is great!.. :)

It's getting simpler, and simpler just to go KA-T.

I agree that 321 ss is better, but if I'm not mistaken, it's the welds that are cracking, not the actual metal tubing. I'd think that a well built 302 SS manifold would be alot better than a poorly welded 321 SS manifold. I'd be willing to bet that even an OBX made of 321 SS would crack just the same.

Anyhow.....here's a link I've used to check out SS.

[kaje36]

ok just got back from the welder, I was realy concered with thow good the guy might be, but he builds titanium reclined racing bikes, and has the most amazing welds I have ever seen.

we got everything tacked into place, the runners on the SScrome fit VERY nicely, I got to do a little porting when I get the mani back, but oh well. he also said the welds were very good on the SScrome. but as far as clearance issues,. I couldnt even come close to seeing one, there is so much room all around it its silly. I could cock the turbo 15 degrees towards the block and still be good. the ONLY issue I saw could be if you but in a t66 turbo or something realy large, and that would be from hitting the motor mount.

I was able to set the T3 flange were I wanted, so I wil have NO issues with a down pipe. it looks to me like it will be on 90 degree bend right down into the exshaust.

when putting the mani on I had to squeaze it past the lines on my Z32 slave cilinder but that was just to get it onto the studs, after that it was fine.

$150 for SScrome SR mani
$100 for KA/T3 flanges ( I spent a little more then this.. but I was stupid and could have goten them cheaper )
I havent goten the price from the welder, but he saie $50 an hour, and I am guessing no more then 3 hours.

I will see about finding a camera and geting pics when I get the mani back later this weekend

Mark

[GoKu]

^^ I thought you acutally bought the KA24DE manifold SSauto is comming out ,I guess I miss the part of using the SR mani and hack the Flanges for a KA .. but isnt the SR ports rounder Vs the Square KA ports? all in all the ETD racing manifold looks quite less troublesome and the price is right.

Off topic ..I have given up on my U13 Altima , Now its time to search for a S13 couple or S14 and Turbo the hell out of the KA.

[95Blue240sx]

Jeff - just curious if you made the ports on your RH mani, square. i got my manifold sitting here just wondering if i should square them out.

[AceInHole]

i just got the turbo so i bolted everything together to compare the flange locations to the stock KA header and it looks almost identical!! i'm wondering if asad's measurements were just really off, or if the SR is just offset or something.

anyways, looks now like i'll just have to reflange the SS autochrome manifold and everything should work together perfectly!! as far as the difference in port shapes, it would definitely be possible to heat up and square off the stainless steel runners. can't wait to get this sucker on!!

[kaje36]

the runners mate perfectly with the flange that I got... but I overpayed so it is probly junk ^_^ hehe but I will be porting it to smoth everything out, and I got Ace's old extra head so I will use that and figure out how everything mates

Mark

[fastpace]

I was wondering if anybody has tried or know anybody that is using the real nissan ka turbo manifolds? I haven't heard anybody talk about these ones. They sell I believe a tubular one and a cast iron version of the tubular one.

you all have been waiting... the SR SScrome Manifold on a KA. I was talking to the welder and he was saying some of the spots were a little hard to weld becouse there wasnt enuph room, but he was able to get at them from the inside. but the manifold fits well. and I cant wait to get my oil lines to start boostin.

the only fiting issues I do have all has to do with the internal wastegate.. or more properly the acuator on the outside.. to get that to fit puts my copoling a little close to the exhaust for my taste, and puting the many and turbo in together it was a little hard to get past the AC line.

also meme ..how long til you stock up on those manifolds? 13 shipping? that sounds good I might have to go for that instead of the ETD manifold, the SSautochrome for the KAs are nice and all but no answer or feedbacks, and im getting impatient of waiting.

the flange I had had round ports on one aide and square on the other. so there wasnt realy a need to reshape. All I did was cut the flanges off, take my car to the welder so we could test fit when he was tacking the flanges on. and he finished welding it wednesday morening.

My car Isnt up and running yet.. I am waiting on my oil lines.. they should be here soon.

it is steel. don't know the thickness. but it is pretty thick. the ports on this manifold are round. i guess they just squeezed the pipe into the port.

[AceInHole]

the flange I had had round ports on one aide and square on the other. so there wasnt realy a need to reshape.

There's no need to reshape, but it's easy enough that you should. It would also make the #3 and #4 runner welds easier to do.

[GoKu]

KAT guys :Disscuss which manifold would you choose?

RH manifold

or meme IAP manifold with longer runners?

I will be running a t3-60-1 ,So would you say the longer runners take time to spool or the shorter style of the Rev Hard ? im open to suggestion,discussion... Thank you

[fastpace]

I am leaning towards shorter runners. like a realnissan manifold. like the quality and options that they have for the price.

[AceInHole]

small update on the KA flanged SS autochrome manifold:

the flange swap is pretty easy. The only problem was with squaring off the runners, since doing so compresses them more, and expanding a square pipe isn't exactly easy. The way we did it was to run the piping into the flange, weld one side, and hammer the other side till it was flush with the flange. The runners ended up looking very nice:
http://www.engr.uconn.edu/~corrales/manifold/IMG_7382.JPG

As for fitment, a quick comparison to the stock header shows they're very similar (if not perfectly):
http://www.engr.uconn.edu/~corrales/manifold/IMG_7379.JPG

One can only assume that since the downpipes should match, the intake piping also should, which then means SR intercooler kits should fit this setup (at least using an S13 cold pipe to meet the KA's TB). Still waiting on oil lines to install, since my Mitsubishi oil fitting uses a different thread.

that is Very Nice , SR bolt ons now ...few mods but more option now since the KA has a Few new Shared friends..

3 things:

1. Based on the new manifold and your experience turboing your KA, do you think that an offset straight T4 would have fitment problems with that manifold (not piping or downpipe fitment problems, but I mean the same sort of problems the topmount manifolds have with coming close to the MC, etc.).

2. Does that OBX manifold have any spots that could accomodate a custom hole for an external wastegate tube?

3. What did you use to hammer the tube square on the inside?...some sort of rounded punch? How long did that hammering take?


thanks,

My friend's T3 fits perfectly with TONS of room (he did the same thing I did but also swapped the turbine flange for a T3 flange). The only problem might be clearing the steering rod.... but i think it's possible to do it. I'll know more when I get mine on the car.
Click here for the pic of his T3 on the engine (http://www.imagestation.com/picture/sraid102/pffc88359363c3057f2f744036733ad14/f9c94550.jpg.orig.jpg)

2. Does that OBX manifold have any spots that could accomodate a custom hole for an external wastegate tube?
The guy doing the T3 also wants to eventually run an external wastegate. From the above pic, you can see just how much room there is between the manifold and the strut tower. Could run a pipe off that and stand the wastegate up, then pipe it down hopefully clearing the steering rod. Once again, I'll know more when I get mine on the car.

3. What did you use to hammer the tube square on the inside?...some sort of rounded punch? How long did that hammering take?
yeah, we used a rounded punch. I don't know exactly how long it took cause I wasn't there when it was finished, but it couldn't have been more than a few hours. Just weld one side, bang into place, weld other side, then do the same for the top and bottom. This is after heating and squaring the pipes, though, which isn't that hard either (bench vise + heat).

you can see here there is ALOTS of room for a WG. but I think for the dump pipe from the WG might be better going around the steering rod. could be an issue if you like your AC ( I havent figured out how much I like it yet ) but you can see in the pic how the line runs if you cant decide eather. but I think I got a good amount of pics around how everything fits. so feel free to take a look. http://www.imagestation.com/album/?id=4287855733

AceInHole - is the guy willing to charge the same if someone else brought the same SR manifold and reweld the KA flanges? or was it more like a favor thing for you ?

Im leaning towards the IAP manifold(keep in mind im U13 Altima) but after looking at Your manifold it would acutally benifit the FWD KA as well, the turbo is place away from the Alternator and above Upper radiator hose ,and also clears more room for a downpipe, as well the benifits of running shorter I/C piping underneath the U13 chasiss,

Altho since its a custom job ,but yet a very good price and connection, Too bad these arent in production for the KA motors,or else it would be a sweet manifold for S13-S14 and U13 Nissans.

I leanning towards a S13 couple(if i can find one 5spd)
if Not I will settling in boosting my U13 again , (car got stolen before with a custom setup) :rant: :rant2:

Now since most of the Manifolds have been brought up to Topic , How many feel Log type VS equal length ?

Shorter runners? PROS?( EXAMPLE :faster spool up? ) CONS?
Longer runners ? PROS? CONS?

I know some of you guys havent yet quite tried it out ..I hope you guys Come back with some feedbacks.I think this will help greatly in learning what type of manifolds the KA really likes to react to even tho differnt setups (t3,t4, t25,so on..) :ughug: (<~discuss discuss...put your thinking caps on guys) ..thanks again in advance .

[nightwalker]

Ace, where did you get your KA flange from? I was the guy doing the budget turbo kit. I might as well get an SS autochrome and copy your setup than trying to work with the cast manifold.

[meme]

i had a log style manifold with big dia runners, but used a .48 turbine. spool was still fast.
on my other car i used the manifold i pics of above. this has smaller dia pipes and so i used .63 turbine. i couldn't really tell the diffrence. there was to many things to consider at the time.

over all i like the log. the log i made used 2 90deg bends cut in the middle. this was used for the turbo inlet. not like the jgs manifold

[meme]

just found the pic

I am leaning towards shorter runners. like a realnissan manifold. like the quality and options that they have for the price.
Correct me if I'm wrong, but doesn't real nissan use a rev hard manifold?

jgs flanges (http://www.jgstools.com/turbo/trbmnf.html)

[kaje36]

thats the flanges I used for mine.. a little expencive..

[andrave]

me too, expensive but thick, high quality, good construction, and they come port matched.

[mbmbmb23]

Is that OBX peice chromed??

[AceInHole]

I got the KA flange from Hotshot for $50. We had ordered 5 at the time as a "group deal" like 2 years ago, but they were ordered at .5" thick. I think the 3/8" ones could be bought from them for the same price.

[AceInHole]

Is that OBX peice chromed??
AFAIK it's just polished.

Mine is a modified SS Autochrome.... which happens to cost less even with the KA flange and additional welding....

Although, I'm a bottom mount fan anyways (only reason for a top mount is bling) so... the modded SR mani works better for me. That KA mani looks nice, though....

I have to agree, bottom mount is much stealthier and allows the use of SR piping...not to mention (what seems to be) less fitment problems.



-m

[andrave]

I've never seen the advantage to top mount, I plan on bottom mounting mine too, especially if I can find a set of stock elbows.

[fastpace]

Well I don't know if anybody has been waiting on the progress of the etdracing manifold for the ka, but they have finally finished the manifold.

http://www.etdracing.com/ka24.html

[GlacierFreeze]

Damn I think we have a winner. Too bad it's not cut between the runners(?) for heat expansion. Looks good though. Only if I had some money haha.

[95Blue240sx]

with all these new manifolds options i kind of regret getting my revhard. but at lease i know it'll work. hehe im still going to use it, but id like a nice tubular manifold, top mount, for the bling factor.

[GoKu]

^^ excatly why I created a Thread for the KA guys, keeping the options open.

The ETD racing is pretty nice , but almost seems like Chris Mays Manifold but a little bit modify ... well Turbo Manifolds are out now...basically all of the options ..so what are you thoughts?

[sykikchimp]

Damn I think we have a winner. Too bad it's not cut between the runners(?) for heat expansion. Looks good though. Only if I had some money haha.
I emailed them with that exact concern, and they said that they had not seen any decrease in the life span of the manifold because of them not being split. He said they did elongate the mounting holes to account for expansion.

He also said they would cut the b/w the runners if you requested it.

and of course.. number 1 reason for top mount *bling*

[Grant]

http://www.store.yahoo.com/phase2motorsports/coenkat3ma.html

thisi is the most similar manifold to the one chris may had on his car.

http://store6.yimg.com/I/phase2motorsports_1779_1125532

[AceInHole]

He also said they would cut the b/w the runners if you requested it.

Or you can take a bandsaw or sawzall to it :p

Also, tomorrow I'm going down to the shop and installing the new manifold and turbo. Having a custom compressor outlet made since I can't find one, and a custom downpipe made while I'm at it ($100 for both). Eventually I'll see if I can compare it to an SR one or just buy one to match the better O2 housing I get when I upgrade the turbo (GTiR T28).

Expect pics of everything tomorrow night.

[kaje36]

nice I cant wait to see it !.. my oil lines should have been delivered today.. so I could install as soon as I find the time.. working overtime this week for suspention.. as soon as I figure out what that might be... also I still got that guy working on my custom A/f and boost gauge mounting.

[ryan hagen]

I've never seen the advantage to top mount, I plan on bottom mounting mine too, especially if I can find a set of stock elbows.


i heard it was to help with oil drainage, i guess sometiems with bottom mount you can run into messed up angles.

ACE, you think that ka/sr manifold hybrid would fit a s13? the s13 exhasut manifold is larger than the s14 so i m thinkin it would fit?
i got a pro welder on my hockey team and he travels with all his gear on a his truck he fixes alot of machinery and custom on site fabricateing so i think he oculd handle it.

[AceInHole]

LoL... funny you say that. JMCN's T04E has a tilted center section to clear the manifold on his top mounted KA-T. Basically.... the only reason you might want a top mount performance wise is for clearance.... but really there's TONS of room, so it's a lame excuse IMO.

The S13 has the same head flange as the S14, so I don't think there would be a problem.

As for that welder of yours, I'm betting he has an ARC welder on the truck... and those are pretty messy. Although, he can probably do it.

[ryan hagen]

he has 2 or 3 different units on the truck generator etc....several gas tanks...... and stuff at his house/shop, but i know the flanges would work but i was thinking stearing clearance etc.

[AceInHole]

lots of room from the turbo to the steering column, AFAIK.

Why go with a tubular manifold if it doesn't have equal length runners? The ETD obviously has shorter runners on 2 and 3. Doesn't preserving the exhaust pulse improve turbo spool? I know that cylinders 1 & 4 and 2 & 3 fire at the same (or almost same) time, so maybe matching those cylinder lengths relative to each other (1 to 4, 2 to 3) preserves the underlying concept of matching the length of the runners in a manifold like this (ETD)?


-m

[AceInHole]

Good news and bad news:

Bad news: the O2 housing didn't fit!! It hit the bellhousing by a landslide, so we measured it again and after welding the difference increased to an inch. Guess we clocked the flange slightly.

Good news: It looks like it'll work as long as you clock the flange out a little bit, or run a small .5" or so adapter to each runner.

Performance: Wow. This thing is SOOO much better than my TD05-12B setup. Sounds better, spools faster, and feels better all the way to redline, running 8psi on my MBC's lowest setting.

My setup:
Since it didn't fit... we made a custom downpipe (i REALLY got tired of my old manifold, which, when taken off, was completely broken into THREE SEPERATE PEICES).

You can see we had to really work to get it to clear the bellhousing, but it turned out to be a success (Bob at Performance Centers of East Hartford did a wonderful job welding mild steel to cast iron). I'm gonna just have a completely new top section to the downpipe made as soon as I can get a T25 outlet flange. Should make for a nice setup. Right now the new downpipe is just another reason the new setup feels so good (old one was crush bent = eww). It's only gonna get better from here.

I'll try to get more pics tomorrow of clearance between the strut tower, block, and steering rack. For now, dare I say.... this setup rivals the smoothness of the SR easily.

[GoKu]

mbmbmb23 -- you've made a very good point and I would also like to hear my opinions as well.

Ace -- Sweet manifold ,glad your up and running ..hope to hear more from you soon.

[meme]

ace; that looks great... ! what turbo are you using now compared to your old setup?

[AceInHole]

T25 off an SR. Boosting 8psi just fine. Ultimately waiting for a T28.

[AceInHole]

with the TD05-12B on a log manifold:
219.9 rwhp 251.4 rwtq (SAE corrected)

Looks to me like a GTiR T28 would be perfect.

[ryan hagen]

ace do you know what alloy or which metal they used for the weld? when i told my guy it would be a ss manifold but not a ss flange he said he needed to know what to use, he said he could look it up but if it had already been done i should see what your guy used.... thanks

[AceInHole]

the weld was TIG'ed, not sure what filler rod he used.

Cool video....I love how the header tubes start to glow. Do you think the welds would crack if you coated the headers with some sort of hot jet coating or ceramic coating?

Also...based on the O2 fitment problem, and assuming I swapped a T4 turbine flange onto the header to use with a straight T4, ....do you think an oncenter T4 would fit better than an off center?

Good work!!

-m

[AceInHole]

i think it'd be easier to use the off center housing and just clock the turbine flange. i still haven't gotten in there to measure the clearance, but i'll try to remember to do that tomorrow. was too busy getting things ready to dyno, so i forgot to do all that.

not sure if the coating would weaken anything at all... if the welds are done right they'll be just as strong as the material being welded.

[meme]

had some free time today. so i wanted to test fit my turbo manifold i've been working on. turns out it puts the turbo to far forward. so it will only work if i do not have power steering. this one will go in the junk bin now.

while i was at it i put the IAP manifold on. to see. here are some pics. i didn't have a turbo to put on but hope the tape measure helps. someone wanted to know if the turbo would hit the master cylinder.

my car is an automatic 1998 se. so you might have a different master cylinder then mine.

http://www.imagestation.com/picture/sraid103/p4c7edbbf8561f9a626c87f6f33a95422/f9afdb25.jpg
the front part of the master cylinder line is about 3.5" high from the edge of the t3 flange.

Can't you just relocate the power steering resevoir?

http://www.imagestation.com/picture/sraid102/p7ca386724db880f1bf3f1073189fdd8a/f9ba17e3.jpg

-not sure if it will fit the altima and i don't have a car here to test it. the turbo flange is pretty far away from the block. so it might hit the radiator.

-the turbo compressor is to close to the power steering pump. not the resivor.

i'll just cut up the pipes and start over.

my next project i will get a greddy O2 pipe and down pipe. Make a manifold around that.

what company is iap again, used to have their site in my favorites but i cant seem to find the link

Feed backs and up to date...

meme -So basically the IAP manifold will hit the M/C ? the IAP seems more benifits our U13 Altimas.

AceInHole -has a custom SR/KA flange ,which makes it perfect for I/C piping from the SR

SSautoChrome - still in the works (KA manifold


ETD racing -finally finsh pictures ...looks more like Chris May's Manifold acutally, a better design compare to the Rev Hard

JGS and F -max are still the old school log style with shorter runners

i can't tell if the manifold hits the MC. but my car is an automatic so the MC is different then the 5spd ones.
if anyone is in So cali and has a t3 turbo with a 5 bolt housing that i can use to take some pics let me know(PM me). i'm in pasadena,ca near the DMV.

This place http://www.full-race.com/ makes them for the SR, and on Fresh Alloy a guy from that company said they will be looking to make some with KA flanges. They are pricey, but they are the best manifolds I've ever seen.


-m

we are prototyping a KA24DE mani right now (similar to the SR design)....should be done in a few weeks :D

[Will fastback SE]

For those of you who are familiar with the Revhard manifold: Is it really that bad a mani? I was planning on getting the RH but it was always being sold for $350+ so I decided I would get the JGS log mani. I just ran across someone selling a brand new RH and we agreed to $200 + shipping but the trasaction is not final yet. $200 sounds like a steal to me but I have no experience with this mani. I know i'd have to slot the flange in between each runner for expansion purposes and the ports are round but can you really go wrong for $200. What do you guys think?

And y do some people have clearance problems and/or mounting problems but others dont? And correct me if i'm wrong but this is a top mount mani right?

[andrave]

me me that looks really good, I wish mine might look half that clean.

[240eggsx]

I believe the RevHard can be use din a bottom or top mount configuration...

[dantang]

Anyone hear anything on the Complete Engineering Manifold? Phase 2 sells it.

[AlexAtPerformanceNissan]

JGS all the way!....A lot better unit overall.... I have heard so many negatives to the RevHard mani...

-Alex B.

[Jeff240sx]

I really wonder how many people are just spewing out regurgitated info when they knock revhard manifolds. I personally own one. Have owned it for over 2 years. Never did anything to it. Never had a crack. My largest complaint is that it spit out a stud for the wastegate. Once I double nut'd that B, nothing happened again. I will port match the mani in a week or so, right before I go ceramic coating it.
-Jeff

[sykikchimp]

the only thing negative about the rev-hard I read about is the turbo placement. A few posts about over heating brakes, or partially melted Brake fluid resevoirs..

[kenjim]

http://www.engr.uconn.edu/~corrales/manifold/IMG_7391.JPG

Just have to trust the weld on the opposite side before going at it, i guess :p

Just out of curiosity, do all the welds on the SS manifold have that ugly black crystillaztion on the back of it? That's a poor weld, they didn't back purge the stainless when they welded it. Which greatly weakens the weld because it's been oxidized during the welding process.
