if u want to use two turbo's i would suggest using a smaller turbo that will spool up rather fast in the lower RPMs like maybe a 2.2 probe turbo to spool up a larger turbo like a T3 or something...but as far as detonation goes, u can upgrade ignition to retard timing under boost or u can install water injection that turns on when under boost...u could possibly run the jet size larger for crappy gas mileage, but then u wont be running out of fuel when u spool up either...and as far as pistons fo u can get some really nice forged ones for 650.00 -
