On A supra. That is ofcourse with 272 cams, and a 3.5-4" exhaust system.
I predict that you are going to limit yourself on stock at around 650-680RWHP. That turbo is great and make sure you have a .81 A/R or maybe even a .70 A/R any bigger than a 81 and the turbo will be a big pig. The turbo should be spooled in the 5K RPM Range..
