1974 Porsche 911 RSR 2.14 Turbo R13 of the Fica Frio Collection, Jersey, UK –
At the 1973 Frankfurt Motor Show, Porsche unveiled a special 911 concept car with RSR flared fenders, a large rear wing, and the word “Turbo” spelled out on the rear. One month later, Porsche announced that they would cease factory-backed racing in Group 4 for 1974. In conjunction with Martini & Rossi, however, Porsche entered a turbocharged Carrera in the Group 5 category. To comply with Group 5 regulations, a 2.14 liter engine was developed with a magnesium crankcase, polished titanium rods, enlarged oil pumps, dual ignition, mechanical injection and sodium-cooled valves. At the rear of the engine was a KKK turbocharger which boosted the new engine to over 500 horsepower. Continued testing and development of this package led to the introduction of the 935 in 1976.
