FOR SALE: 1975 Porsche 911S Coupe 3.8L Backdate

This 1975 Porsche 911S Coupe underwent an extensive restoration project. The car’s bodywork was chemically stripped and sandblasted, and various modifications were made. It received widened steel 911 Turbo fender flares, custom bumpers, LED projector headlights, and unique paint in Kingston Grey with Porsche logo stripes. The interior features custom bucket seats, leather upholstery, a custom dashboard, refurbished gauges, and a MOMO Prototipo steering wheel.

The car is powered by an air-cooled Porsche M64 flat-six engine bored to 3.8 liters. It includes upgraded components such as Mahle Motorsports RSR coated pistons, Webcam RSR camshafts, and Aasco titanium valve retainers. The engine also has a modified ignition system, GT3-style headers and sport muffler, and custom intake setup with individual throttle bodies.

The 915 manual transmission from a 1986 Carrera was rebuilt and paired with a WaveTrac limited slip differential and upgraded Turbo axles. The suspension was sourced from a 1986 Porsche 930 Turbo, with adjustable sway bars and Bilstein shocks. The car rides on 15” Braid RSR-style wheels dressed in Pirelli Cinturato P7 tires. The brakes were also refurbished and a power brake booster was installed.

This meticulously crafted custom 911 backdate is up for auction via PCARMARKET. Every detail of this high-end build was executed with precision and no expense was spared. The car has been driven sparingly, with just over 975 miles on the odometer since its completion.
