These cars ran the Bosch Motronic 7.2 system, which uses an electronic throttle body, linked to an electronic gas pedal (also known as drive-by-wire). When installing an engine into one of these cars, you need to use an electronic throttle body and corresponding crossover tube that matches that engine. (I.E. use the electronic throttle body from a 2000 or later 996 Carrera when installing a 3.4 engine).
