Book Excerpt: 1965-1989 Porsche 911 Repair Manual THE PORSCHE 911 IS A CAR OF ITS OWN IN THE WORLD OF THE SPORTING MOTORIST

Originally produced as a Coupe of 2 liter engine capacity, it was a natural successor to the Type 356, which itself started life as a Porsche designed body assembled mainly around standard Volkswagen components with a modified VW Beetle type engine. Although not differing greatly in body style, the 911 model, introduced in September 1964, was a very different car mechanically. A new rear-mounted, flat-six, dry-sump engine was introduced, with carburetion by a triple choke Solex carburetor for each cylinder bank. Power was transmitted through a conventional diaphragm spring clutch to a 5-speed transaxle which drove the rear wheels through twin driveshafts. The result was an outstanding 130 mph plus sports coupe. Subsequent development brought about both de-rated and up-rated versions, replacement of the Solex carburetors by Webers, the introduction of the Bosch plunger pump fuel injection system, and later the intake-airflow-controlled K-jetronic injection system. Concurrently there were minor transmission modifications, and in August 1971 a new transmission was introduced for the 1972 models. Meanwhile, the semi-automatic Sportomatic transmission had been introduced, which also underwent considerable modification for 1972.
