When unveiled in February 1993, the Porsche 911 Turbo 3.6 was the most powerful production model Porsche had ever offered in North America. This rear-wheel-drive, widebody 911 featured a single turbocharger and delivered an impressive 355 horsepower. Porsche achieved this by turbocharging the 964’s updated M64 3.6-liter engine, replacing the outgoing 3.3-liter unit.
As the 964 generation neared its end, Porsche introduced an even more potent version—the Turbo S. Each car was built by Porsche Exclusive’s Sonderwunsch (“Special Request”) division and equipped with unique performance enhancements. Production was expected to be limited to fewer than 100 units.
The Turbo S featured the X88 “Works Increased Horsepower” engine, inspired by Andial-built race engines for Brumos Racing’s IMSA cars. Upgrades included a larger KKK turbocharger, an improved intercooler, modified cylinder heads, high-capacity fuel injectors, a four-pipe exhaust, and aggressive camshafts, resulting in 385 horsepower and 384 lb-ft of torque. A G50 five-speed manual transmission with a ZF 40% locking differential managed power delivery.
Porsche initially built 39 X85 Flat-Nose Turbo S coupes for the U.S., later adding 17 standard-nose “Package” models, making them among the rarest air-cooled 911s ever. Now, one of these coveted Turbo S 3.6 “Package” models is available for auction on Bring A Trailer, offering enthusiasts the chance to own one of the rarest air-cooled 911s ever produced.
Finished in Grand Prix White, it features a revised front splitter, asymmetrical 959-style quarter panel air intakes, a louvered rear spoiler, and quad exhaust tips. Additional exterior details include a rear window wiper, aerodynamic side mirrors, a power sunroof, and headlight washers. Inside, Classic Grey leather upholstery covers the seats, dashboard, and door panels. Features include power-adjustable front seats, air conditioning, power windows, and a Porsche CR-1 cassette stereo with a six-disc CD changer.
It rides on polished 18″ Speedline Cup wheels with Turbo-script center caps, wrapped in Michelin Pilot Sport tires. Braking is handled by red Porsche-branded calipers over cross-drilled rotors. The 3.6L M64/50 flat-six, equipped with the X88 power kit, produces 380 hp and 384 lb-ft of torque. Power is delivered to the rear wheels through a five-speed manual transaxle with a limited-slip differential. A strengthened flywheel, clutch, and quad-exit exhaust system with modified heat exchangers were standard for Turbo S models.
