The Chrysler 3.3 and 3.8 engines are V6 engines used byChryslerfrom 1989 to 2011. This engine family was Chrysler's first 60°V6 enginedesigned and built in-house forfront wheel drivevehicles, and their first V6 not based on aV8.It was designed as a larger, more powerful alternative to theMitsubishi 3.0 V6in theminivansand debuted in 1989 for the 1990 model year. They were later also used in somerear wheel drivecars 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.

History
editThe original 3.3 engine, as well as the larger 3.8, arepushrod enginedesigns. 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, Michiganfor theJeep Wrangler.Both use a cast ironblockand aluminumheads.
3.3
editThe first of the family, the 3.3 liter engine's actualpiston displacementis 3.3 L; 201.4 cu in (3,301 cc) with a 93 mm × 81 mm (3.66 in × 3.19 in)boreandstroke.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 systemwhich 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 fortransverseapplications in Chrysler's minivans, but was also used in alongitudinalfront-wheel-drive setup on 1993-1997LH platformcars. It was last used in 2010 for Chrysler minivans before the introduction of the new 3.6 LPentastar enginefor the 2011 model year.
DesignatedEGA,the 3.3 was built atTrenton EngineinTrenton, Michigan.It usesSequential fuel injection,has rollertappetsand 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:
- 1990–1993Dodge Dynasty,Chrysler New Yorker,Chrysler Imperial,(replaced the 3.0 LMitsubishi6G72engine)
- 1990–2010Chrysler minivans
- 1993–1997Chrysler Concorde/Dodge Intrepid/Eagle Vision
3.8
edit
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]ThisEGHversion was also built atTrenton EngineinTrenton, 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:
- 1991–1993Chrysler New YorkerandChrysler Imperial150 hp (112 kW), 213 lb⋅ft (289 N⋅m)
- 1994–2010Chrysler minivans
- 2007–2011Jeep Wrangler (JK)
- 2009–2010Volkswagen Routan
SOHC
editA singleoverhead camshaftwas an addition to the lineup for 1993. Introduced with the 3.5 L engine, this design spawned theDOHC2.7 LChrysler LH engine,as well as the 3.2 L and 4.0 L variants.
