Hey guys, I have an OBD-II H22A4 in my 97 prelude. I was wondering if I can put an OBD-I H22A head on my engine? If i can would it even be worth it? I mean the H22A is only rated with 5 more hp. Would the midrange power increase?

 

I dont really have a good answer for you for this, but is it really worth it for 5 hp?

 

Well thats what i'm asking. I think that the midrange power would be better and would make it worth it. A friend has the H22A head and if i want it, i can have it.

 

just keep the head. swapping heads aren't as reliable as just sticking with the head you have now. what are your plans for the car?

 

just get a exhaust or something and you will get that 5hp without tearing into the engine

 

or an intake, highflow cat, or headers.
