Switzer Performance, a car tuning company from Ohio developed a twin turbo kit for the already powerful Porsche 911 GT2. Professional tuner Tym Switzer and his guys at SPI created the package to deliver 800 hp for the Porsche 911 GT2. With those numbers it will really put you back in your seat, but Switzer aimed to also give it a smooth ride with an equal power curve. It runs on normal 93 octane gas and is basically a complete bolt on kit consisting of custom SPI headers, an aftermarket exhaust system, new intercooler setup, and to top it off, two GT30R turbochargers.

The ECU has been left alone, making the bolt on kit easy to install for the novice tuner.
