would be interesting to be able to drive a few different cars with differenty specced engines and turbos to see how thy compare.

Most people on here can only really comment on their own car.

One thing I can remember is Mark telling me that he can make a GT30 respond like a t34 and make a GT35 respond like a T4.

he also said that a GT35 is good for about 100 bhp more than a T4.
