The Porsche 911S continued as the top of the line 911 for the 1970 and 1971 model years, sitting above the contemporaneous 2.2L 911T and the 2.2L 911E. As with the T and E variants, Porsche would upgrade the 911S to a larger 2.2 liter engine. The version in the 911S, Type 911/02, featured mechanical fuel injection, and was rated at 180 hp. During its production years it was available as a 2.2L 911S Coupe and a 2.2L 911S Targa. Vehicles from this period with significant modifications will be found in the 911S custom market. For model year 1972, the 2.2L 911S was replaced by the 2.4L 911S.
