im boosted now runing 9lbs stock motor.. im pulling the motor in the next few months but trying to do my research on pistons and rods to go with and the Compression Ratio?
9psi? the motor will be fine as is, so long as it's in decent condition. should be no problems keeping your lower boost b16 with stock compression ratio. unless you just feel like rebuilding it, then i would go somewhere around 9.3-9.5 C/R if you're using a small-medium size turbo. first step though is to decide on a final power goal...
