Imo when you mod a car it should be purpose built. What are your plans with the car? Top end? Large track? Small track? Autox? DD? 1/4mile? Quick example if you are shooting for top end large track with high hp and long gears. Your car wouldnt fair well with autox as a car with short gears and moderate hp. And visa versa. GOod luck with what ever you choose.
