over the last few months my mechanic and i have discussed different options for the two turbo 242GTs were builing, if money permits these will be completly finished out group-A type cars that will kick ass at the track and make a few mustang drivers crap their pants. but any way what im wondering is assuming any type of pinging aside (direct-port water injection, stand alone ECU w/ programmable fuel manigment and a water cooled and sprayed intercooler) would we be better off power wise to go with standard low compression pistons or high compression pistons from a B23 bottom end. Boost should be in the mid 20s psi range thanks to hybred turbos. please help i am yet to get a really good anwer with reasoning
