I'm an engineer but not in the automobile industry so I can't say how much it would cost. I see a lot of cars at the track with turbochargers and superchargers added that run with little problem. Friend of mine has a supercharger blowing 7 psi on his NSX with nothing done other than adding the supercharger and intercooler and chips (plus bigger brakes). BMW has done it and is only asking about $5K more for the car that puts out 300 ft-lbs of torque from 1400 - 5000 rpms. I see lots of Miatas on the track that are either supercharged or turbocharged. How do I know? It's obvious when I cannot run them down on the straights with my Porsche that runs 16 psi boost.
