In south Florida there is Breathless Performance Parts. I know for a fact that they recently installed a super charger on a 2000 convertible. Give Ernie a call. I am taking my '01 Z06 there Tuesday to have step headers and x-pipe work. He is a supporting vendor.
spoke to mike norris norris motorsports central folrida about 6weeks ago before traded my coupe for new z06, while discussing various performance mods he told me that very shortly he would be installing prochargers he seems to be establishing a good rep but i understand his shop is relatively new , i do know he spent many years working on vets at the dealer level i don,t have phone # handy but he write c5 column fo corvette fever you can probably find him through them
