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.

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.

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.

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)?

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.




Completed downpipe:


Now for the bling:



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.

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

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.

T25 with ss autochrome manifold:

sorry, scanner isn't working.

Video can be found here.

Looks to me like a GTiR T28 would be perfect.

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

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!!

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.

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.


the front part of the master cylinder line is about 3.5" high from the edge of the t3 flange.

Cam

Wow! I just want to thank Ace, meme, and the rest of you guys for all this info. You're really helping those of us who are still in the planning stages... it's much appreciated.

Don't scrap it, finish it up and sell it to a turbo Altima guy....it's gotta fit a FWD car.

Can't you just relocate the power steering resevoir?

^^ Yeps the IAP manifold looks perfect for the U13 altimas, likes mines = D
altho going to find a S13 couple baby~!

meme

-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.

phrozen

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

GoKu

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

meme

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.

meme

check out

import-autoperformance.com i think that is the link. they have a pic of it on the car.

240Stilo

Their kit is pretty expensive.

i don't know him. for some reason i could not post a reply there. anyways you can see the turbo setup on the llink above.

FR Javier

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

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?

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