Ok i got a sohc zc and im am more than happy with it performance wise. its made a nice touch to my crx. What i'd like to know is would it be worth it to put a vtec head on the block. If so what types of gains can i expect and what head do i use? i was told the y8 would be best to use since it would boost compression. And if i do this head swap what ecu do i need? Right now i got the pm7 i think its out of an integra. Or do i just get a vtec controller? Any info from you guys would be appreciative. If it wasnt for this site my car would'nt be where it is today.
