The innovations of 1972 and 1973 brought about the most popular engine of all in the Porsche line, the 2.4-liter engine. The 911T type now used a new K Jetronic continuous fuel injection system. With such new increases in the torque and power, the 911T had to have a much stronger transmission, this brought about an H pattern gearbox that put 1st gear in the upper left corner, and 3rd gear to the upper right corner.

The 911 was turbocharged in 1974. The engine was increased to a 3.0-liter engine, in 1978, while the 260 PS was increased to a 3.3-liter engine with 300 PS, and an intercooler was installed under the rear spoiler.
