http://www.jdm-option.com/eng/....html^^SR TOMEI Expreme, SR equal length, SR stock.

buy this:http://www.frsport.com/Ichiba-....html

then take a cheap equal length and this to a muffler shop or equivelant, have them cut both flanges off and put the CA mani flange on the SR mani..i would do this i just dont have the cash for something like this right now. I'd think this setup has alot of potential, i just can't do anything at this time to prove it, so i'm asking for someone else to help me! lol

anybody?

I would'nt take it to a muffler shop, I would take it somewhere and have it tigged, like a local weld shop. Most muffler shops use oxy-acetylene to weld, I would want that welded with a wire feed welder (Mig,Tig). A machine shop has plenty of ability to make you a flange for your CA also, I would'nt use some thin a** ching chong flange on my full race manifold, you dig?

I like this idea. Well, besides chopping up a Tomei manifold but whatever. Plus your car would sound awesome with the unequal length runners.

If I were him I would just fluxcore birds*** a manifold together and call it a day, do it homemade.

im really trying to inspire someone on here with the same curiousity as me to do this..i thought of this last summer and its been bugging me ever since because it seems like a hell of an idea, but its just out of my budget

If you haven't noticed, the Tomei Expreme manifold is pretty much a stainless copy of the stock CA manifold. Just another reason why the stock manifold rapes apes.

yes both the expreme and stock CA and SR manifolds look the same, but the flow of the expreme is better. i guess i should find an actual dyno so as to see the difference between how much power the car made with stock manifold vs. the Tomei manifold

QFT.Just port and polish the stocker and you have the so called Extreme(?)DOnt bother spending money when the stocker is ready for action right now.

Every used Trust manifold I have seen is cracked to hell. And that design should put the wastegate right into the steering shaft.

wow that worthless attempt at a sales pitch got owned.

If you guys want nice manifold's why not just have one made by a fabricator? it'll cost you, but it would be nice.

If you're going thru the trouble of swapping flanges....just save up for a full race or equivalent.

You could always Extrude Hone the OEM manifold, and maybe Swain coat it. I've seen 350+whp SRs with OEM manifolds like that. Don't know why so many people want aftermarket manifolds for T2xs anyway, the whole point of a small T2x turbo is response, and you give up a lot of RPM with an equal length manifold.

years ago on freshalloy was a thread on a budget turbo ka24de.He got an sr20 cracked XSpower manifold, T25 & 370s = throwaway items.Welded stock KA flange to sr header and hacked his oe air flow meter for the 370s.Doubled his tq, doubled the fun... dyno'd a solid 310 ft-lbs tq using "junk"!

I never sweat all this equal length bull. A pipe with 2 90 degree bends won't flow the same as the same length pipe with one 90 degree bend etc..I learned how to make weld-el manifolds from an experienced cat. Inexpensive with no cracking problems. **Best performing I've seen had small runners with a direct short path that converged at the turbo flange.**Logs have airflow making 90 degree bends, firing straight into a tee, pulses directly colliding etc. Sure they work "OK", but we won't even waste time making those either

It was probably "AceInHole"...he did a 300hp KA-T by using junk parts....got that much HP from an SR T25 too...and a hacked maf too.
