Prelude engine and DSM turbo manifold?
 

I was informed that the DSM turbo manifold (mitsu eclipse) matches up pretty good with the H23 DOHC 2.3L prelude engine, you just have to redrill the bolt holes. This way you can do a cheap turbo kit using DSM parts. Well I need to know if this will also work alright on the H22a (2.2L DOHC Vtec). I know this engine has higher compression and can run less boost, but we would probably stick on a thicker headgasket to lower the compression a bit. By the way, its my friend that has a '97 prelude and I'm gonna help him out. I'm a mitsu man myself. I had a Eclipse GSX and now I have a Stealth (3000GT). I'm just wondering how close the h23 and h22 engines are. About the same exhaust manifolds?

to my knowladge it wont work on a h22. no one i know of has done it.

The h23 manifold won't bolt up to the h22, and I don't think that it is possible to only modify the bolt holes on the manifolds to get it to fit, so it must be structural differences, or the exhaust ports are spaced slightly differenty, or something similar. On that note, if the DSM manifold will work with the H23, I don't think it'll work with the H22.

Dang, looks like he won't be gettin a turbo.

I think I might just buy a '92-'96 Prelude Si someday and do this for myself. ;)
