While there are some mods that can be done to make the CVT CRZ more spunky, it will never be on the same level as some of these performance cars. My EcoBoost mustang for instance has 310 HP stock with a turbo. Some of the S550 GT's are pushing 800+ HP with twin turbos. The CVT is the bottleneck in this case. Hondata did some testing and found Honda CVT's began to see scoring of the metal band at around 220+ HP. If you do a sprintex supercharger, CAI, bored throttle body and bigger injectors, you can probably push the car to about 150-170 crank HP (tuned). Add a healthy amount of suspension mods and the car will handle like a dream on the twisties.
