I have an 89 supra turbo a/t. Goin to be buildin up my 7mgte this winter and I'm starting to order parts its not my first supra build but I'm tryin to go over the top on this one. What is a better piston to run that I can make the most power on, trying to break 500 or as close as possible. But here's the kicker I want to make it pass emissions. By adding Y pipe with before the cat. To run straight pipe and running separate parameters on ecu to make it run clean enough to pass. Does anyone think this is possible? Also what cams and springs could I run that will hold the power but still keep me street legal?? if possible I will be running eagle h beam rods to push the piston. Also will bein goin to R154.
