I dont remember the model number and everything of my clutch. But i have an ACT stage four clutch and it grips big time however if you use your Supra as a daily driver its not good for that but if its a weekend racer or what not its great and id imagine if it holds up well enough now it should be good for the Single Turbo Upgrade. It might be a bit before i can tell you how well it holds that.
