I have a 94 prelude with a H23A1 engine. First off, is this engine worth building? When I say building I mean putting this car into mid to high 12's (no slicks). I've noticed that the H22a has about 60 more hp. Would I be better off putting an entire H22a in my car or can I head swap H22a head on to my block, thus making it a vtec (I assume computer modifications will follow?)? I'm new to this rice scene so I hope I'm making sense. Thanks for any input.
