awd or rwd? I think it would be more fun (if your going to go through all the work of converting a rear drive system onto a Civic) to just install the S2000 powerplant or simliar rwd setup, like an SR20DET from a Nissan. Regardless of what you decide to do, it's going to be a considerable amount of work. I haven't really spent any time under the back of a CRV either so I can't give you much help their either. Good luck with it.
