That would be crazy, but I can see how it might work. A supercharger is belt driven and works into the intake correct? And a turbo works off of exhaust gases correct? So, you can have a supercharger on the top of your engine while you have the turbo where the exhaust is. Super air flowing in and turbo air flowing out. Crazy.
I heard from some kid that you can get a twin turbo setup for your integra. A bigger turbo fed from a smaller turbo... I don't think they exist. But I have heard ppl talking about them...and think it would be stupid and pointless. If the turbos arent the same size, its not truly a Twin
