i would say low 12's too but the 70 mm might hurt you since going bigger isnt always the best choice. start with stock and max it out before upgrading

Don't worry about hurting your car. Mine has 150k on the clock. All thats done to mine is a new timing chain, and valve springs. Got mine set up on 25 lbs right now and it has no issues. I don't even have an alky chip yet, so my timing is really low too.

87limitedt,warm air and stickey tires low 13s,cold air and stickey tires 12.60-12.80's,no stickey tires 13.80's or worse. 20psi with higher timing.i would not run any more than 20-22psi on the stock turbo with the alky being a must,if you feel you need to, just upgrade the turbo.never broke anything on 20psi on a stock turbo and 12sec et's all day long with a good hook.
