..or you could just leave it the way it is.
Circuit cars are not designed for 1000ps.
The only practical use I can see for a 1000ps car is for max-speed competitions.
If you need to boost power to run at the same level as the 787B then do it. However, the 787B doesn't have 1000 horsepower and the Autobacs NSX is probably the best JGTC car in the game.
Sooo.. ya.
Get better?
