Injectors
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.
Engine | pre-series 1 N/A | series 1 N/A | Series 1 Supercharged | Series 2 N/A | Series 2 Supercharged | Series 3 N/A | Series 3 Supercharged |
---|---|---|---|---|---|---|---|
RPO Code | LN3 | L27 | L67 | L36 | L67 | L26 | L32 |
Fuel Injector size | 19 lb/hr | 22 lb/hr | 28 lb/hr | 22 lb/hr | 36 lb/hr | 22 lb/hr | 33 lb/hr |
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.
