I believe that it will be fine. However, I suggest that you don't drag off too many GTO's, as the screaming and smell of burnt rubber will offend the GTO drivers.
Marry them up and take it easy. The tranny will take what you can dish out, it is the same as the one in the 280 petrol engine, which has more HP than the turbo diesel.
