Supercharged s2000 Owner here. I can't speak for all s2k owners, but I don't think I'd consider the f20c transmission *that* stout. The > 500whp s2k guys know they can pop the gear box. I know if I were turbo'd at my power level (500+whp )the diff and tranny would be on borrowed time. The strength of the s2k gear box is that it'll still shift smoothly at >9000 rpm.

As an aside, the FA20 has a FI option that the s2k community is missing, a positive displacement supercharger. Given the option between 400 whp, turbo, centi blower, or posi blower, I think most would take the posi blower as it has a great power curve and is maintenance free. Though I do understand the f20c potential is greater than the fa20, the fa20 has its own merits.

I forgot to mention I'm curious if there is room for centri-blowers. The kits for the s2k use the available space up front which I think is more than the FRS. There is no posi blower kit, so that leaves you with turbos for FI. If you hurt the bottom end of an F20C, it's not a cheap fix. Yes, I understand the engine is strong, but without good safe guards setup (and even with them), things can happen and motors get damaged. The mahle pistions are >700 and the other option are sleeves (dry or wet) and forged slugs.

Of course if you're doing a swap of this magnitude, this is a small chunk of the overall budget. I just mention this so folks are aware of some of the f20c drawbacks.
