Man be careful, a bone stock turbo supra was alot of car for me when i got it as my 3rd car, i now have the exact mods and its pretty hard to control and i have an Auto tranny. Plus im running on only 12psi. Luckily I have 265's in the back to handle the power and im starting to get wheel hop as it is. So i cant imagine stock tires. I say lower the boost to 5psi learn the car then turn it up after you get tires!! Good luck and be safe
