Chris Bergemann at Horsepowerfreaks.com is running a T-78 at low boost with a stock fuel setup (edit -- and a 6spd). I recommend you get ahold of him.
T-78 in an auto and on stock fuel isn't such a good idea. If you don't have plans to upgrade the fuel, I suggest a sp60 or smaller. If your keeping the auto trans I wouldn't go any larger then a sp63. A larger turbo is going to be a bitch to drive daily with an auto. Just all depends on if you can go without boost until 4k+ rpms..quick said:Chris Bergemann at Horsepowerfreaks.com is running a T-78 at low boost with a stock fuel setup.
