The Heart of a Racer: Engine and Drivetrain Enhancements
This 1977 Porsche 911 Coupe has been transformed into a formidable track machine, powered by a 3.8-liter flat-six engine, originally sourced from a 964, and heavily upgraded with high-performance components. These enhancements include a Mahle piston and cylinder kit, Pauter rods, and Elgin 306/288 cams, all designed to maximize power output and durability. The engine’s advanced MoTeC M600 ECU ensures precise control and optimal performance, complemented by TWM throttle bodies for improved throttle response and a custom exhaust system for enhanced flow. A GT3R oil pump and a front-mounted oil tank contribute to the engine's reliability under extreme track conditions, making it a true marvel of engineering for racing.
Beyond the engine, the vehicle's 5-speed manual transmission features aftermarket internals, ensuring robust and precise gear changes during high-speed maneuvers. A Hargett Pro-915 billet shifter provides a direct and tactile connection, while the Tilton clutch kit and Smart Racing mounts contribute to the drivetrain's overall resilience and performance. The suspension system is equally impressive, boasting an ERP 935 front suspension kit, FOX Racing shocks, and aluminum rear control arms, along with an ARB sway bar, for exceptional handling and stability on the track. Braking power is supplied by Brembo hardware, equipped with cooling ducts, a Tilton brake-bias controller, and AccuBrake anti-rear lock-up, guaranteeing superior stopping capabilities. This comprehensive suite of modifications underscores the car's dedication to track performance, placing it in a league comparable to factory-built track specials like the Porsche GT3 RS, albeit with a unique vintage character.
Interior and Exterior: Purpose-Built for Competition
The interior of this classic 911 has undergone a complete transformation, stripped down and configured purely for competition. Essential modifications include a Sparco Pro 2000 racing seat and a Schroth harness, providing critical driver support and safety. An 8-point roll cage significantly enhances structural rigidity and occupant protection, meeting the stringent requirements for track use. Further contributing to its race-readiness are a Tilton pedal box for precise control, a lightweight carbon-fiber dashboard, ProComp Ultra-Lite gauges for clear data display, and a window net. A comprehensive fire-suppression system is also installed, highlighting the meticulous attention to safety in a high-performance environment. Every element within the cabin is geared towards optimizing driver focus and performance during demanding track sessions.
The exterior of the 1977 Porsche 911 features a lightweight body kit, designed to reduce overall mass and improve aerodynamic efficiency. Composite rear windows further contribute to weight reduction, while SPA carbon mirrors offer a sleek, functional design. A removable diffuser enhances downforce, crucial for maintaining stability at high speeds. The vehicle rides on 18-inch Formula 43 wheels, which are both lightweight and robust. Despite its competitive nature, the seller acknowledges the presence of some chips and scratches, which are typical indicators of a car actively used for track purposes. Recent maintenance, including new tires in July 2022 and a camshaft sensor harness repair in April 2022, ensures the car is in optimal condition. The extensive service records and included spare parts provide valuable documentation of its rigorous upkeep and continuous development over years of dedicated ownership.
