Any 02 or newer JDM STI motor will spin to 8K+rpms. I've got my rev-limiter set at 8500rpm but there are guys elsewhere in the country that routinely spin them to 9 or 10K. Boost without lag, get a supercharger bro, you'll just have to live with the lag. You can run twin-scroll turbos or variable geometry blades to cut down on it but there will always be lag with a turbo.Originally Posted by THX712517
