I'm building a divided T3 manifold for my CRX, and was looking for advice on a good way to build a small 3-4" collector for it. I'm just not sure if I should angle the two collectors (away from each other), put them right up against each other...ect.

I was hoping someone could post up some pics of a way they found was the best way to do this. Sch40 pipe is so damn big for the tiny T3

TIA,
Bryson

 

I used 1.25" sch 10 els for mine. made two seperate collectors then welded them together. i've seen people make over 600hp on 1.25" els. even lisa kubo was running in the 9's with a 1.25 primaries. sch 40 1.5 is going to be a pain if you ask me. going holset power?

I'll use 1.5 pipe because I have it, and it'll fit the ported head flange properlly. Right now I'm trying to make the collectors by cutting the two pipes so that the outlet will be roughly the size of a single 1.5" pipe. Once I have it tacked together I'm going to try and squish the outlet to fit the shape of the flange. Right now it looks like that should work without a problem. I'll know by the end of today whether or not that'll work.

No Holset for me. GT3082R with a ATP divided T3 housing.
