Talking to Millers machine shop they advised me to run forged pistons. They say cast pistons won't withstand cylinder pressures I'm putting them through. Even with a small turbo. I just don't want to spend that kind of money on this 7m. I'm pretty much done with it and want to move on. Only problem is we're in the middle of this Dave Ramsey thing, so fixing up the Supra is on the low side of my priority list. We'll see how things go in a few months from now.
