Good luck having a N/a keep up with a GTP, even a stock one.

If you honestly trying to make power and go "fast," completely forget about modding a N/a Grand Prix. You need to either top swap or put a turbo kit on it. But in the long run, a turbo is the way to go. It's the best, "Bang for your buck." You'll make much more power in the long run.
