the 4agze is not built for a supercharger, it is built for forced induction. many people who own buick regal gs (supercharged 3.8L) remove the supercharger and replace it with a turbocharger. both systems have advantages, so you need to look at exactly what you want out of the car. turbochargers have become very popular because the generate "free" horsepower. they do not need to be run by the engine, but rather the flow of air. superchargers require horsepower to run them. superchargers also require a lot more work to change the ammount of boost, whereas with a turbo this is very simple.
