Which turbo is better? Which one would require the most extra money to be able to kill mustangs 'n such>?? I just wanna be able to have a street racing ass whooper. I can get the occasional stock mustang with the flowmasters, but the ones with basic mods can get me. Basically. How can I make my car faster? Which turbo? or should I get a custom-built supercharger??? I don't really want to have to pay out the ass for internals if I don't have to. So, which kit gives the most HP to the wheels???
