When the 993-generation Porsche 911 Turbo was introduced in 1995, the automaker’s engineers in Stuttgart were well on their way to making the biggest change in their flagship model’s history. The switch from an air-cooled to a water-cooled engine was about two years away. To close out three decades of air-cooled performance, Porsche unwrapped a gift to just 183 of its most loyal enthusiasts: the 911 Turbo S.

The 911 Turbo S is built on the standard 911 Turbo’s twin-turbocharged flat-six and 959-derived all-wheel-drive system with a power boost to 424 hp for the American market, as well as a slightly upsized rear wing, quad tailpipes, and bespoke air scoops tucked into its rear wheel wells. Inside, the Turbo S featured carbon fiber trim and full leather upholstery. The 911 Turbo S arrived for the 1997 model year and took advantage of a few upgrades over the twin-turbo 993’s inaugural year such as an engine control unit that could be re-flashed and modified, upgraded transmission input shafts, and special center caps for its alloy wheels.

Though it was well received at its launch, history has been especially kind to the ultra-limited 993-generation 911 Turbo S. Porsche celebrated its 70th anniversary by unveiling a very special one-off 993 Turbo built from a new-old-stock body shell, dubbed “Project Gold.”

The low-mileage Arctic Silver over Boxster Red leather example offered here is undoubtedly one of the finest original Turbo S models currently available. Its striking paint and interior combination honors Porsche’s then-new mid-engine Boxster roadster. The 911 Turbo S came well equipped with gathered leather upholstery for the front and rear seats and extensive leather-covered details such as the door panels, center console, seat belt housings, and even many of its control switches. It features its correct 911 Turbo S-specific details such as its wheel center caps, yellow brake calipers, and carbon fiber interior trim pieces. This example’s only modifications from stock are a period aftermarket audio head unit and tasteful window tinting.

Sold new in Miami, it later passed through owners in Connecticut and California. Faithfully preserved in private collections, the 911 Turbo S has added just 500 of its 13,500 miles in the last 12 years. A recent turbocharger rebuild and full engine service by a Porsche specialist was completed, ensuring the 911 Turbo S’ drivability. The 911 Turbo S rides on correct, Porsche Classic-approved Bridgestone Potenza performance tires.

A Porsche Production Specifications certificate confirms its original delivery specifications and will be included with this very attractive and highly desirable 911 Turbo S.
