Pontiac had a motor that “they wanted to put in the 1982 version but they ended up scrapping that idea”(Wikipedia 3). Early in the third generation they wanted to put a turbo 4.9liter engine in the car but they ended up scrapping that idea at the last second. Instead, they decided to go with a 4 cylinder on most models. In the middle years they were putting 2.8 and 5.0liter engines in the cars. In the later years they used 3 different types of engines, the rare 3.1liter V6, and the not so rare 5.0 and 5.7liter
