The good thing about owning a Mustang is that not only are they cool but there is virtually an unlimited amount of aftermarket parts available for them. You could put a low boost supercharger on the car, but you would have to modify the fuel system(pump, injectors,regulator, etc.) to accommodate it. Plus you would have to modify the exhaust with headers, h pipe, and cat back. Starting out you can switch the rear end gears to either 3.55's or 3.73's, maybe a larger throttle body, and a Flowmaster exhaust system. You can also add headers and an h pipe if you want.
