has anyone heard of someone runnin 12psi on 91 octane with a b16a with stock compression of 11:1? the block has been decked .040, head has been decked .030, and its running oem replacement p30 pistons. no machine work to the rods/crank. head has been ported, exhaust has been matched, intake has been cleaned/matched, tb has been polished/matched. its runnin stock cams, with ferrea turbo valve train. my question is, can this be done without suffereing severe detonation?
