duPont REGISTRY Live presents this highly modified 1989 Porsche 911 Carrera Speedster, a rare one-year-only G-body variant finished in Guards Red over a Black leather interior. Combining the unmistakable styling of Porsche's iconic Speedster with a documented Proto Tech Stage 3 turbocharged engine build, this example delivers performance well beyond factory specifications while retaining its numbers-matching engine case and desirable G50 5-speed manual transmission. Accompanied by a Porsche Certificate of Authenticity, Proto Tech documentation, previous celebrity ownership, and a clean CarFax, this Speedster offers a unique blend of collectibility and performance.

Built for a single model year, the 1989 Speedster paid homage to Porsche's legendary open-top sports cars with its lowered windshield, minimalist cockpit, and distinctive double-hump rear tonneau cover. This example further distinguishes itself with desirable Turbo Look bodywork, including wide rear fenders and a paint-matched Turbo rear spoiler, giving it the aggressive appearance of a 930 while maintaining the exclusivity of the Speedster platform.

Finished in Guards Red, the exterior is complemented by 17-inch Fuchs wheels and the signature double-bubble tonneau cover that has become synonymous with the Speedster name. The combination of the wide-body stance and classic air-cooled proportions creates a purposeful appearance that reflects the performance enhancements beneath the decklid.

Inside, the cabin remains focused on the driving experience with Black leather seats, a factory rear-seat delete, air conditioning, and a period-correct Blaupunkt Charleston cassette radio. A custom red-faced instrument cluster adds a subtle motorsport-inspired touch while preserving the analog character enthusiasts seek from an air-cooled 911.

Power comes from the numbers-matching 3.3-liter turbocharged flat-six, upgraded through a comprehensive Proto Tech Stage 3 build. Highlights include 2mm-over Nikasil pistons and cylinders, Porsche Tech Group B camshafts, upgraded fuel delivery components, dual fuel pumps, a Turbonetics P-Trim turbocharger, revised engine management, and a high-intensity ignition system. Additional upgrades include Bilstein suspension, 930 front brakes, drilled and vented rotors, a factory short-shift kit, and a limited-slip differential, creating a significantly more capable driving experience while retaining the engagement of the G50 manual gearbox.

This 1989 Porsche 911 Carrera Speedster is offered with one key, its Porsche Certificate of Authenticity, and Proto Tech documentation. Combining one-year-only Speedster production, documented turbocharged performance upgrades, and desirable air-cooled Porsche pedigree, this example represents a compelling opportunity to acquire a truly distinctive 911.
