Paired with an aggressive pair of cams, a higher compression ratio will be a cood combination. You will need some sort of fuel management with raised compression since the fuel and ignition curves will change.

The P30 (JDM B16A) piston seems to be a good choice since it will raise your static compression ratio to around a pump gas friendly 11.5:1. The PCT (JDM B16B) piston will raise static compression to around 12:1 which will require a decent tune in order to run the car without detonation and you may run into valve-piston clearance problems with large cams.
