R13 1974 911 RSR 2.1 Turbo Cropped T-Shirt

The first turbocharged racing 911, and the Le Mans Legend: The (R13) 1974 911 RSR 2.1 Turbo. This was the final of only four RSR 2.1 Turbos built. It is among one of the most important racing cars of theirs in existence with it's victory of 2nd overall at the 24 Hours of Le Mans with Herbert Müller and Gijs van Lennep despite losing the car's fifth gear.

This car takes credit as having proved the German auto-maker's race car manufacturing capabilities. They wanted to produce a race car that looked like the 911s available to consumers, and with the 930 production (marketed as the 911 Turbo), the RSR 2.1 was born.

Their racing division developed the turbocharged 2.1-liter flat-six, which made 450 hp. With its air/oil-cooled, magnesium-crankcase engine, Bosch mechanical fuel injection, and KKK turbocharger and intercooler, it was able to push 500 hp and 405 lb-ft of torque. The five-speed transaxle with it's own oil cooler paired with that engine for the most part, was recognizable as a 911, but was hardly stock. The RSR had fiberglass fenders, doors, front and rear valances, and front and rear decklids which were all engineered for weight reduction which made the RSR 2.1 weighing in at just over 1,800 pounds. It also had extremely wide flared fenders, and a huge rear wing to keep the car stable at high speeds. All four of the RSR 2.1 Turbos built for the 1974 racing season would all have the famous Martini Racing red and blue livery that we have illustrated by the distinguishable colours.

The R13 goes down in history as one of the most successful 1974 RSR 2.1 Turbo and during it's retirement, it had just five owners after it left the team in 1975. It received an engine rebuild in the early 2000s, but remains in it's original condition bearing all of the flaws it received during it's racing career.
