well some ppl know i am selling my full setup and everything the car will go to a family member,

ever since we did the h22 swap, we had a hell of a time, getting things to idle, flow, and run right: So many things could be the problem, w/ vtec and wiring and just so many problems, we could never fix:

question is: If i just take the h22 head off and put on a h23 and swap ecus.. will that be enough not have any problems? even with the oil squirters and h22 internals,?

 

I highly doubt anybody has ever tried this before .. there will be a loss in power for sure, but considering most of the sensors and such are throughout the head for ideling it could work ...

give it a try .. what've you got to loose? some labor ?

its been done b4, plenty of times. Do a seach on H23 vtec and you will c. Theres a little more then just swapping the the head but it can be done, I am 100% possitive cause my buddy is doing it right now !!

Need to replace the oil control orifice in the top of the block to take away VTEC oiling.

Your compression ratio is going to jump with the H23 head (smaller cc) so if you're running a 10:1 h22a piston it will be like 11:1. Well maybe a little less becuase you have smaller displacement.

Other than that since it's only a 2.2 your h23 ecu will probbaly be a little rich.

i got hondata to fix that, i just want to get this car to a family member and keepig it the way it is, is going to **** them off in a week lol

i know not a lot of ppl go from h22 to h23, but i might do it, if its not that hard:

 

going to try this , if the current option dont work


ok,

So i need to block the vtec oil ?
also, i need to adjust the rom i have to h23 not h22? or you think i can just tune the one i have now, to work correctly?

Guess i need to look for h23 head and intake manifold, should be a decent/easy swap right? Thats bout all i would need correct?

Yeah block the oil, well the plug just restricts the amount of oil that goes up there.

I think an H22a map will be fine to start with for the H23. But remember you should swap injectors or you'll be way off. H22a head are 330cc while H23 head are 240cc

 

it's possible that it will take away some of the problems. allthough i wouldn't put all my money on it. but i find it ironic that you are puting the h23 head on the h22 block. reason being was because i was considering frankensteining that for my own purposes. alot of people do the h23 block and h22 head. yada yada yada. but with the calculations that i've made and a few interesting idea's. i would think that the reverse order would be very potent for what i'm going to try to do.

sorry. a little off topic of me. i've just been thinking alot (with my car in pieces)

but yeah. it might cure some of your problems. a lot of people seem to have trouble with idling and the dreaded "hesitation" when they do h22 swaps into si's. let me know how it comes out.

see i wish i had someone around here that would be able to look over teh swap and see what is messed up and what is wrong

cause the guy who help do mine, i cant get a hold of , he was military and is gone. so to be honest i dont really know exactly what most of the problems are or could be.. only place would be the dealer, but i am srue to get an rip in price ..

 

i did the h23 vtec head swap but not the h22 non vtec swap https://honda-tech.com/zerothread?id=661998 good luck
