I'm pretty sure I holed a piston in my ZC sohc motor in a 91 CRX. It's prepped with a Jackson blower (6 lbs) and fuel controller. How can one be sure that the fuel controller is working, as the motor must have gone lean with boost, and with my bad hearing, I can't hear pinging. Are the pistons and gaskets in a stock ZC motor compatible with other 1.6 motors. Is there any problem with blowing a ZC motor. Are there any opinions on blower camshafts as long as I'm this far into the motor, As far as performance go's, it went like hell......for about 500 miles........Byron
