A heavily modified 1977 Porsche 911 Coupe has hit Cars & Bids with a current bid of $77,777, offering one of the most extensively race-prepared air-cooled builds currently on the site. Finished in blue and black with a stripped, competition-focused cabin, the car carries a clean Washington title but no functioning odometer, meaning true mileage is unknown. The seller is listing it on behalf of the long-term owner, who has had the car since 1999.
For buyers comparing high-spec performance Porsches, the market currently spans everything from pristine modern GT cars, like the 2023 Porsche 911 GT3, to celebrity-owned road models such as James May’s Porsche 911 Carrera S. This ’77 race build lands at the opposite end of the spectrum, this is purpose-engineered for track duty, with a parts list that reads closer to a club-racing catalogue than a classic 911 restoration.
Engine, Drivetrain and Race Hardware
Power comes from a 964-sourced 3.8-liter flat-six, upgraded with a Mahle piston and cylinder kit, Pauter rods, Elgin 306/288 cams, RS-spec valves, TWM throttle bodies, a GT3R oil pump, a front-mounted oil tank and a custom exhaust. Management is handled by a MoTeC M600 ECU, and fuelling comes via a Fuel Safe Systems cell.
The 5-speed manual transmission features aftermarket internals, a Hargett Pro-915 billet shifter, a Tilton clutch kit and Smart Racing mounts. Suspension upgrades include an ERP 935 front suspension kit, FOX Racing shocks, aluminum rear control arms and an ARB sway bar. Braking is handled by Brembo hardware with cooling ducts, a Tilton brake-bias controller and AccuBrake anti-rear lock-up.
With this level of modification, the car is firmly in track-special territory, sharing a similar spirit, though not the same originality, as ultra-focused factory machines like the Porsche GT3 RS.
Interior, Exterior and Condition
Inside, the car is fully race-prepped: a Sparco Pro 2000 seat, Schroth harness, 8-point roll cage, Tilton pedal box, carbon-fiber dashboard, window net, ProComp Ultra-Lite gauges and a fire-suppression system. The exterior features a lightweight body kit, composite rear windows, SPA carbon mirrors, a removable diffuser and 18-inch Formula 43 wheels. The seller notes some chips and scratches, consistent with track use.
Recent work includes new tires (July 2022), a camshaft sensor harness repair (April 2022) and a long list of mechanical upgrades completed over years of ownership. The car includes two keys, service records and spare parts.
Why It Matters
For anyone seeking a road-legal classic 911, this isn’t it, but for buyers after a serious race platform, the value is compelling. Air-cooled Porsche builds with MoTeC management, 3.8-litre conversions and full 935-spec suspension rarely come up for public auction.
With decades of ownership history, extensive hardware and transparent mechanical documentation, this 1977 example offers a turnkey route into vintage racing without the cost of building a car from scratch.
