Think about it, the newest Mustang GT and Camaro SS make about that, bone stock. And they're faster, too. A Chevy SS (if you want a roomy 4-door) makes around 390whp stock, does 12s@110-111, and can be a reliable 650whp car with a blower on like 9psi and 91/93 octane. You'll curb-stomp an RC-F, even with a blower and be far more reliable than the 2GR-FSE is capable of in a safe or driveable manner.

I doubt putting a S/C running less than 9psi on a 2grfse with some miles on the clock is going to seriously hurt it, given i am not racing and launching.

I'm not saying buying a gs-f is a bad choice compared to getting a 350 tuned or supercharged but if your only looking for an extra 50 hp & 50 ftlbs of torque, a tune, exhaust and some other mild work are way cheaper than a whole nother car. Plus I would be morally obligated to baby the gs-f; there's no way I'd be taking that car on a road trip. Doesn't mean I'll never get an f of some sorts, but I don't feel bad putting miles on the 350.

With the 20k, I would be get 150+ HP and a respectable car. I decided not to go with the RCF because owning a coupe with a family inconvenient. If I wanted to make my IS350F as fast, I’m looking to pay about 10k- 13k for the S/C installed. (Parts and labor)

I mean if you only want 50hp increase thats different. Not worth upgrading to a GSF. But do expect reliability to go down with a S/C.
