CRV engine == K24A1 block has a lower static compression ratio (9.6) and in my POV it's less optimum for K24/K20 frank motor. Perhaps upgrading to a higher comp. piston like the Accord Euro pistons (10.5) is more suitable for the setup.
IMO, it something worthwhile to look into...
also, u need k20 oil pump, K20 etc etc...
