You could get a jdm zc motor. Its dohc and pretty cheap.
www.hmotorsonline.com has them. or is it hondamotorsonline.com I forget. Those are pretty strong motors.
The zc motor would be an easy swap too. Hmm as for body kits if you have the money I would get the Black widow series 2 kit they ahve for your crx its freakin bad.
