H23 turbo

[EastSideRider]

So I have decided that I want to do a boosted H23 swap into my 91 DX sedan. I have a 91 standard hatch that I swapped a B16 into.......so swapping is not a new issue to me. I tried searching.....but I could not seem to find anything. I was just wondering if anyone makes a good H23 turbo mani......or are the H22 turbo mani's able to be used on the H23?

Any help or advice would be greatly appreciated.

Thanks,

well one search that i found out with honda-tech.com is that the manifolds are o oo o and o o o o

dont remember which is which...but different.

you could do the dsm turbo setup on the h23...but to answer your question, the h23 and h22 are 2 totally different port patterns, they are not interchangeable

Ok......so I have a lot of DSM friends. So what you are saying is I could take a DSM manifold......and it bolts directly onto an H23 head (with minor mods)? Thats pretty interesting

I did find someone that produces an F22B manifold, will that work?

Thanks guys

I thought the h22 was dsm compatible, and the h23 had ports like the f22b1/2...?? F22B=F22A Ports, so if the f22a fits the dsm manifold, and the h23 fits the dsm manifold, in conclusion the f22b would fit the h23. So basically, if h23 ports= 0 0 0 0, yes f22B manifold will fit. But if h23 ports= 0 00 0 no go. h23 guys need to chime in here.

Well.....from some of the things I have been reading here.....and on HMT and H-T........I may just be better off getting another F22A1. According to my research.....the F22 has a stronger bottom end on top of that. Ehhhhh, might as well just boost it F series style

good choice... but you can always swap heads...

This is very true......the JDM F22B is always a choice as well, but I think I will keep this car USDM........ehhhhh, i'll just see where things go I suppose

look ur best bet is to go get a manifold for a f22a same bolt pattern. DRAG has a turbo kit for the H23. the motor that was in my car H23 was already turbo with the DRAG kit

So.....I can just get a DRAG mani for the H23 and it bolts over? Sounds good.

H23s are o o o o

yes you can. i have that drag manifold from that h23 and its just sitting on the f22 motor. it fits NO PROBLEM. i rather use a h23 motor for boost cuz of its closed deck block rather than a open deck block found in all the f-series and the h22. less flex in the cylinder wall area is a good thing.

h23 exhaust manifold is same as f22a and different from h22 and f22b.
h23 and f22a 0 0 0 0
h22 and f22b 0 00 0
4g63 (dsm manifold) 0 0 0 0 thus fits onto f22a and h23 and the f22b manifols will NOT fit onto h23 or f22a !

[CB7DOHC]

prodigy meant any vtec f22b# sohc exhaust manifold wont fit a h23 or f22...the dohc jdm f22b, h23, and f22a are interchangable..

[prodigymb]

personally neevr seen a jdb f22b exhaust manifold, so i dont know if its interchangeable. but h23 and f22a and DSM(redrilled) definetly are
