I'd be interested in these questions as well. It would be nice if we could buy a S2000 for $20K and throw a turbo or supercharger on it for another $6K or so and have a nice track car that is still good at autocrossing!!

How are the rods/pistons/crank in the car? I am assuming they aren't forged?? I'll be reading this forum as much as I can so hopefully i'll have most of the answers, but anything more can always help!
