12 psi cause i'll still get good boost and it won't destroy my gas mileage. Im building a d16z6> was going with some ac8a aluminum ycp pistons that took stock compression down from 9.2:1 to 8.5:1. i wanted to remain stock rods but from what im hereing stock rods won't hold 12 pounds. so now im trying to figure what internals i'll go with. if any1 has internals that they're willing to see i have money and im willing to buy. but opinions and previous knowledge is greatly appreciated.
