Porsche 911 Carrera RSK 3.0 1974 for sale

Le Mans Participant 1974 and 1977 European GT Champion Vehicle 1974 One of only six Kremer RSK 3.0 built Driven by Wollek, van Lennep, Fitzpatrick FIA Historic Technical Passport Coming from 24 years of previous ownership Numerous race victories Fully restored Introduced in 1974, it marked a decisive step in the development of the 911 as a pure racing car. It was the direct successor to the 2.8 RSR and was developed at Weissach specifically for use in Group 4 of international motorsport. The goal was to create a vehicle that was both technically and dynamically at the top of its class and that further developed the extraordinary base of the 911. The heart of the 911 Carrera RSR 3.0 was an air-cooled six-cylinder boxer engine with a displacement of 2,992 cc. Porsche used a reinforced aluminum case, which replaced the previous magnesium case of the 2.8 RSR. The engine was equipped with dual ignition, Bosch mechanical fuel injection, and a compression ratio of 10.3:1. With this combination, the naturally aspirated engine of the RSK 3.0 built by Kremer produced 330 hp at 8,000 rpm, 15 hp more than the factory RSR and a torque of 303 Newton meters. This was achieved through modified engine components, such as the camshafts. The transmission was via a five-speed manual gearbox, which transferred power precisely and robustly to the rear wheels. Despite the absence of forced induction, the RSR 3.0 offered impressive acceleration and agility thanks to its reduced weight of around 900 kilograms. Porsche placed great importance on lightness and aerodynamics in the RSR 3.0. The body was partially made of fiberglass-reinforced plastic, which further reduced weight. The hood, doors, bumper, and the iconic ducktail rear wing were also made of lightweight materials. The fenders were significantly widened to accommodate larger 10.5-inch front and 14-inch rear wheels. The plexiglass side windows and thinner metal panels emphasized the rigorous approach to lightness. The RSK 3.0 also received revised aerodynamics from Kremer, which ensured greater aerodynamic downforce and stability at high speeds. The braking system came partly from the legendary Porsche 917 and offered exceptional deceleration values. Porsche installed center-lock wheels, as are still common in professional motorsport today, to allow for quick wheel changes. The chassis was optimized for racing use, with modified wishbones, Bilstein dampers, and adjustable stabilizers. This combination gave the vehicle a neutral and precise driving behavior and excellent traction. Inside, absolute functionality reigned. The cockpit consisted of a bucket seat, a roll bar, a small steering wheel, and essential instruments. Everything served to save weight and to focus completely on performance. The 911 Carrera RSR 3.0 dominated the GT class in 1974 and 1975. Numerous private and official teams successfully used the vehicle. Particularly impressive was the fact that Porsche often competed against much more powerful competitors and yet achieved victories. Its low weight, excellent balance, and reliability made it one of the most successful GT vehicles of its time. A total of about 50 units were built, of which only six of the modified Kremer RSK 3.0. Many older 911 models were subsequently converted to RSR specification to approach the performance of this vehicle. Even after the arrival of the 911 turbo models, the RSR 3.0 remained a favorite among many drivers due to its purist mechanics and immediate driving feel. The model still represents a symbol of the technical expertise and perfectionism with which Porsche and Kremer shaped motorsport. It embodies the companies' philosophy of extracting the maximum from every detail with precision, lightness, and engineering. This vehicle is considered not only one of the most beautiful but also one of the most successful 911s in history. Chassis 0006 is one of three RSK 3.0 built by Kremer in 1974. The vehicle was used by the Samson Kremer Racing Team in the 1974 European GT Championship, which driver John Fitzpatrick won with this RSK that year. Additionally, Kremer participated in 1974 with chassis 0006 in other international endurance races, including the 24 Hours of Le Mans. After a sensational qualifying, where the car with starting number 68 was the fastest in its class and 15th overall, drivers Hans Heyer, Paul Keller, and Erwin Kremer started with hope. After a good start to the race, unfortunately, the team had to retire the Porsche in the fifth hour due to piston problems. Below is a summary of the races held in 1974: After the 1974 season and championship, Kremer Racing sold chassis 0006 to Louis Meznarie, a resident of Paris, who was the official engine preparation expert for Porsche from 1971 to 1983. Until 1977 for the 24 Hours of Le Mans, the RSK 3.0 was converted into the aerodynamic 934/5, concerning only aesthetic components and not the engine. In a letter dated April 5, 1977, to Meznarie, the A.C.O. communicated that his application to participate in the 1977 24 Hours of Le Mans had been accepted and that he was invited to the previous test. The subsequent letter of May 20 assigned the vehicle starting number 43. In a period photo, the vehicle is visible with the 934/5 body during the scrutiny of Le Mans 1977. In qualifying, driver Thierry Sabine recorded a time of 4:31.6, which was not enough to participate in the main race. Below is a summary of the race held in 1977: After Le Mans, the RSR was reportedly sold to Carlo Noce of the Italian motorsport team, who kept the Kremer Porsche until 2001. At that point, it was purchased by a Porsche collector based in Monaco, who undertook a complete restoration, aiming to bring the 0006 back to its 1974 season splendor, with the starting number 68 that it carried to Le Mans. During the 2023 and 2024 seasons, the RSR was used in the following Classic Endurance races across Europe. In 2025, the collector decided to sell the Kremer Porsche after 24 years of ownership, bringing the vehicle into the hands of Mechatronik, where it was stored for a year as part of the internal collection. For participation in historic motorsport events, a FIA Historic Technical Passport was issued, valid until the end of 2033. Two expert reports summarizing the history of 0006 are available. Additionally, numerous documents and images from the 1970s are available.
