to turbo a car properly ull def need to do a couple of things first (and anyone correct me if im wrong).yes u will need new forged pistons.u will want lower compression pistons so that the FI will be more effective.stock compression is around 12 to 1 or something like that so u will want to go to about 9 to 1.also u will need to sleeve the motor.Darton makes good sleeves(cause i have them

).also upgrading the rods would be a good idea as well.a good turbo kit is about 3k and u get what u pay for.u could go with ebay crap and maybe do alright for a little while but for the long haul that stuffs gunna break.also make sure there is a shop that can tune your car as soon as the turbo is installed.do NOT drive around with an untuned FI engine.sounds like u have plenty of cash to get it done so good luck

.only reason why i know this stuff is that im saving for a turbo kit as well and have already talked to a shop about it.
again im no expert but i hoped i helped
