i have owned 4 x t78 cars and at the time i thought they were ok, but since then ive had a t51spl and now a custom bb garret, the t51 and garret are far superior, i will NEVER go back, i can make more power with either of the above turbos and still have reasonable driveability.
Why would u want to toot around off boost anyway, i like to drive my cars and use the power, t78 are just nasty for a everyday street car.
i would suggest anyone who owns a t78, drive a twin turb car or decent single car with similar power and im sure u will see the light too.
