I am in the process of putting a forged bottom end into my 2001 2v engine, my question is, I plan on using the FRPP Blower kit except I am going to use a 9# pulley, I will also have blower cams, l/t headers and an offroad x pipe. My question is, would 18cc dished pistons lower my compression ratio too much? Around what compression ratio would i be running with them? Thanks for any help.
