I was looking around, and everyone is going for a Ls/Vtec swap in there CRX. Any reason? Cheap? Fast? would GSR not be better? maybe more expensive. And when doing a Ls/Vtec, you need the Bottom end of a Integra Ls engine. but what head do you use? any B serie vtec head? or there's some better ones to use on this? and when doing this, i guess you change de piston, camshaft, rings, head gasket..etc..?
