Those wanting 911 GTS power in their 911 S have a new, albeit expensive, option package available from Porsche. The package, called the Porsche Exclusive 3.0S Powerkit, will give 911 S owners 30 more hp from the car’s 3.0-liter flat-six engine, along with several other upgrades.

The additional power, which is up to 450 hp total, is achieved with a pair of larger turbochargers and updated engine electronics. The package adds the Sport Chrono package, which itself adds a steering-wheel-mounted driving mode switch, analog stopwatch on the dash and dynamic engine mounts. The Powerkit also adds a sport exhaust and modifies the brake-cooling system.

The package is limited to the 911 Carrera S, the 911 Carrera 4S, and 911 Targa 4S. Older turbocharged 911 Carrera S, 911 Carrera 4S and 911 Targa 4S models can have the package added if they are already equipped with the Sport Chrono package.

Those wanting the option will need to shell out $12,350 for 911s equipped with the seven-speed manual. Those with the PDK dual-clutch automatic will pay $12,870, an additional $520.
