The Type 933 was the last 911 to receive the air-cooled treatment before constricting environmental regulations forced Porsche into water-cooled engines. Of the 993-generation, the Turbo is among the most prestigious given its high horsepower, spectacular performance, and limited availability. In 1997, Porsche introduced the vaunted S variant of its coveted 911 Turbo line. The high specifications of the Turbo S featured various upgrades aimed at increasing overall performance as well as satisfying any requirements its driver demanded of it. As such, it is safe to say that as one of the last adaptations of the air-cooled 911, the 993 Turbo S has wholly cemented itself as a true collector and driver’s car.

The first of its improvements came in the course of a more powerful version of Porsche’s tried-and-true SOHC 3.6-liter flat-six engine. The engine benefitted from upgraded K24 turbochargers, along with alloy cylinder heads and case. Power increased to 424 hp at 6,250 rpm and 423 foot-pounds of torque at 4,500 rpm. The advance in power meant a new Bosch Motronic engine-management system along with the addition of a secondary oil cooler to cope with the intense heat developed by the engine. It was improvements such as these that initially were developed for Porsche’s legendary 959. Other upgrades included front brake cooling ducts in place of fog lights, active rear brake cooling intakes above the rear wheels, a two-tier decklid rear wing with ram air to the intercooler, along with a number of carbon fiber suspension components.

The 911 Turbo S was not confined to just engine upgrades but a host of other technical improvements. Figures such as the Turbo’s 0–60 time of just 4.2 seconds and a top speed of 185 mph are certainly impressive; however, in order to rein in the incredible high speed, the Turbo S was fitted with large 12.68-in. cross-drilled, multi-piston ventilated disc brakes. This would give way to excellent overall braking as the car weighs in at just over 3,000 lbs. Feeding the prodigious power to the pavement is the engaging six-speed manual transaxle mated to the permanent all-wheel-drive system that affords excellent road-holding in any environment and under any circumstance. As for the numerous exterior upgrades, the car sports a specially designed “Aerokit II” that features a redesigned front bumper, large side intakes, and fixed rear wing.

RM Sotheby’s is proud to present this outstanding, extremely low-mileage 993 Turbo S. Delivered new to its Pittsburgh, Pennsylvania, owner in 1997, the car later changed hands in 2010 to a dedicated Porsche enthusiast. Realizing the car’s incredible condition and rarity, the fastidious owner took great care to maintain the limited production Turbo S in as-new condition. And at just 88 miles on the odometer, the car is as pristine as when it was delivered some two decades ago.

However, this Turbo S is much more than the sum of its limited mileage. Finished in striking Speed Yellow over a factory special-order two-tone yellow and black leather interior, the Porsche immediately exudes a unique presence. The yellow motif continues through the interior as the center console, racing-style sport seats, rear seats, and seatbelts are finished to match. To complement the eye-catching interior, carbon fiber is laced throughout on the steering wheel, dashboard, doors, and various other components. The car was also specially ordered with Porsche script floor mats and a high-tech infrared security system.

This exceptional 911 Turbo S retains its respective owner’s manuals, factory literature, and window sticker. Also included is an untouched tool set, air compressor, tool, jack in its original green pouch, spare keys, and space-saver spare wheel. Furthermore, it is offered with a Porsche Certificate of Authenticity, confirming its original factory specifications.

As one of only 183 produced for the U.S. market, this exceedingly low-mileage Porsche 911 is sure to be one of, if not the most original Turbo S in existence.
