Fueling

The stock injectors on a 3800 really are not that great for higher horsepower builds. There is a little bit of headroom with the L67 injectors, but once you start using a turbo or a small supercharger pulley you will start to exceed the capabilities of the stock injectors.

The 3800 came equipped with different injectors depending on whether it's a series 2 or 3, and if it is supercharged or naturally aspirated.

The series 3 3800 is a bit different than prior versions because it utlizes a returnless fuel system and the injectors use the EV6 connector. Series 2 and earlier motors will use a retun-style fuel system and EV1 fuel injectors.
