Engine upgrades can improve your car's acceleration and speed. You can add more aggressive cam, stiffer valve springs, improved intake and exhaust systems as well as a turbo or supercharger to get more power out of your engine. Combine several engine upgrade types to get the most out of your engine. But remember: extra power alone will not win races. Winning performance calls for a balance between power and handling.
