is it an auto or manual? with manual id say supercharger, with auto id go turbo either way i hope theres alot more going on then just throwing one or the other on. everyone saying SC is better because its better for low boost is right but if your doing it right and building a motor for it you can run lower compression and up the boost. if your not building a motor but wanna go fast get a 100 shot and save for a motor build.
