Considering buying a 91 CRX to drop this engine into. The crx has a D series motor how much of a pain in the ass is this going to be to swap in? what other parts will I need. Do I need a new tranny? Am I better off just dropping it into a 94 integra RS, if so what tranny should I use for that? Crx is much cheaper and lighter so I am leaning towards it I geuss I need some advice.
