Eh depends on what power level you want and how dependability is also a concern when deciding to turbo/SC. Superchargers tend to have much linear and smoother power bands but you wont get huge HP numbers from most kits but dependability is much better on a S/C car. Turbo is awesome if you want to always have the ability to upgrade, and turbo cars when built right can put out huge crazy Hp numbers, if you ever have any questions feel free to give me a buzz. We are working on a 2001 BMW M coupe and we have swapped the tranny from a 5 to a 6 speed and are installing and Active Autowerke Level 1 supercharger kit bringing the power level up to the 480hp range.
