You could argue that you buy a Vtec for the top end scream, not the lack of torque, so a supercharger changes the driveability characteristics of the engine, where as a turbo is more in keeping. Never driven a Vtec, but cant see the appeal.
I actually showed this ad to a mte of mine who ran a straipped out S2000, and he was very tempted to buy it. However, he is currently installing a turbo in his mk1 Mx5, so cant justify it
