The Chrysler 3.3 and 3.8 engines are V6 engines used byChrysler from 1989 to 2011.This engine family was Chrysler's first 60°V6 engine designed and built in-house forfront wheel drive vehicles, and their first V6 not based on aV8. It was designed as a larger, more powerful alternative to theMitsubishi 3.0 V6 in theminivans and debuted in 1989 for the 1990 model year. They were later also used in somerear wheel drive cars like theJeep Wrangler.
The engines were produced in two major variants differing by theirpiston displacement: a 3.3 L; 201.4 cu in (3,301 cc) and a 3.8 L; 230.5 cu in (3,778 cc). The 3.3 was dropped after 2010 with the Chrysler minivans, and the 3.8 was dropped after 2011 with the Jeep Wrangler, ending 22 years in production.
| Displacement | Years | Power | Torque |
|---|---|---|---|
| 3.3 L; 201.4 cu in (3,301 cc) | 1990–1993 | 150 hp (112 kW) | 180 lb⋅ft (244 N⋅m) |
| 1994–1995 | 162 hp (121 kW) | 194 lb⋅ft (263 N⋅m) | |
| 1996–2000 | 158 hp (118 kW) | 203 lb⋅ft (275 N⋅m) | |
| 2001–2010 | 180 hp (134 kW) | 210 lb⋅ft (285 N⋅m) | |
| 3.8 L; 230.5 cu in (3,778 cc) | 1991–1993 | 150 hp (112 kW) | 213 lb⋅ft (289 N⋅m) |
| 1994–1995 | 162 hp (121 kW) | 213 lb⋅ft (289 N⋅m) | |
| 1996–1997 | 166 hp (124 kW) | 227 lb⋅ft (308 N⋅m) | |
| 1998–2000 | 180 hp (134 kW) | 240 lb⋅ft (325 N⋅m) | |
| 2001–2007 | 215 hp (160 kW) | 245 lb⋅ft (332 N⋅m) | |
| 2008–2011 | 197 hp (147 kW) | 230 lb⋅ft (312 N⋅m)[1] |
The original 3.3 engine, as well as the larger 3.8, arepushrod engine designs. The 3.3 was introduced in 1989 with the 1990 Chrysler Imperial, New Yorker, and related K-series models, and was joined in 1991 by the 3.8. Production on the 3.3 was stopped in 2010 after a run of 5,076,603[2] engines, while the 3.8 remained in production until May 2011 inTrenton, Michigan for theJeep Wrangler. Both use a cast ironblock and aluminumheads.
The first of the family, the 3.3 liter engine's actualpiston displacement is 3.3 L; 201.4 cu in (3,301 cc) with a 93 mm × 81 mm (3.66 in × 3.19 in)bore andstroke. In 1994, the 3.3 received a 12 hp (9 kW) increase in power to 162 hp (121 kW) due to a newair intake. In 2001, the engine was fitted with avariable intake control system which boosted output to 180 hp (134 kW) at 5000 rpm and 210 lb⋅ft (285 N⋅m) at 4000 rpm. The engine was especially suited fortransverse applications in Chrysler's minivans, but was also used in alongitudinal front-wheel-drive setup on 1993-1997LH platform cars. It was last used in 2010 for Chrysler minivans before the introduction of the new 3.6 LPentastar engine for the 2011 model year.
DesignatedEGA, the 3.3 was built atTrenton Engine inTrenton, Michigan. It usesSequential fuel injection, has rollertappets and featuresforged steelconnecting rods, a one-piece castcamshaft, and either a cast aluminum or reinforced plasticintake manifold. The 3.3 has atiming chain, and is an interference engine meaning that the valves will collide with the pistons in the event of a timing chain failure.
Vehicles using the 3.3 include:

The 3.3 was bored and stroked to 3.78 in × 3.43 in (96.01 mm × 87.12 mm) to create a 3.8 L; 230.5 cu in (3,778 cc) version.[1] ThisEGH version was also built atTrenton Engine inTrenton, MI.
The 3.8 received an increase in power of 12 hp (9 kW), for a total of 162 hp (121 kW) in 1994 via a new intake system. In 1998 the compression ratio increased for a total of 180 hp (134 kW) and 240 lb⋅ft (325 N⋅m). In 2001, like the 3.3 the 3.8 received the symmetrical reinforced plastic intake plenum and revised camshaft which boosted output to 215 hp (160 kW) at 5000 rpm with 245 lb⋅ft (332 N⋅m) at 4000 rpm.
Vehicles using the 3.8 include:
A singleoverhead camshaft was an addition to the lineup for 1993. Introduced with the 3.5 L engine, this design spawned theDOHC 2.7 LChrysler LH engine, as well as the 3.2 L and 4.0 L variants.
