Second generation - Engines

Porsche initially opted for the six-cylinder boxer with 2.7 litres of displacement and Bosch K-Jetronic mechanical fuel injection. There were two performance levels of 150 PS and 210 PS available for the high-torque boxer engine, which was designed for regular petrol. Over the years, displacement rose first to 3.0 litres (from 1975) with 200 PS and then to 3.2 litres with 231 PS after the 1983 summer break. In 1975, the 911 Turbo arrived, drawing its 260 PS of power from 3.0 litres of displacement. From 1977, the engine grew to 3.3 litres and 300 PS of power, aided by the addition of an intercooler.
