I think the bottom end could handle it. However, I am not sure that you understand how hard it would be for you to replace that head gasket. It would take a long time, and a little money. Would it work, yes. Do you want to, no. The few horses that you would gain could be gained on a dyno, or with some bolt ons. Don't fool with a good thing, experiment on a shitty engine. Just my opinion.
How much would those cost me and where could i get them? Also i plan on putting a head from a '97 up prelude so i can supercharge it. Can my crank and rods hold that compression ratio and boost without blowing up?
My car is an OBD1. Its a '94 prelude Si. Back in november i had to put another engine in it and i found a good deal an an h23 ordered from Japan. I want to put a head from a '97 up prelude so i can add a supercharger because i prefer super over turbo. I'm hoping the vtec head will swap on to my h23 block and i know i'll have to get the ECU for the '97 up and get a wiring harnes to go from OBD1 to OBD2 which is whats in the '97 up. I just dont know how easy this swap will be since i've never seen anyone else do it. Also will the instrument panel in my dash still work cuz i know the dashes in the 2 cars are very different. I know i kinda got of teh whole compreesion ratio topic but any help on these questions would be great. I can get a head from a 92-96 and 9'97 up for about the same price and pretty cheap because my friends dad owns a just yard and said he'd give me everything i needed (IM, Head, EM, ECU) and anything else for like 500 bucks. Just tryin to make a decision so i can get started.
im not sure what all you would have to do to get that head on there, you have to remember that the 4th gen h22a has a different block design than that of the 5th gen, 4th gen being superior of course. if you plan on throwing boost at it, keep the h23 compression. ummm good luck?
^ word, you don't want high compression with boost. Also not only are the blocks different between 4th and 5th gens but since you have a OBD1 setup, I've heard there will be issues when putting on the OBD2 head in a very recent post on hondaswap
I think it's a pretty bad idea to try get get an OBD2 head onto an OBD1 block. BlackJDMdeath had a good point about the two different block designs (closed deck vs. open deck), and I think that's just going to give you even more headaches.
