Can anyone tell me the origin of the 3.8L JK engine (petrol). Is it a brand new engine or is it used on some other vehicle? I thought it may have been used in the Chrysler Vogager. Anyone........

 

Yeah, it's been used in the minivan for some time, I think it also saw some action in the Pacifica. So it's not new, and is quite proven.

[EDIT] Here's a list of vehicles:

1991-1993 Chrysler Fifth Avenue and Chrysler Imperial
1991-present Chrysler minivans
2007-present Chrysler Pacifica
2007-present Jeep Wrangler

 

3.8l V6 Has Been Around Since 1991 And Revised About 4 Times To Get It Where It At Today

 

Its actually a proven design but an all new block and timing cover.. So Its half and half.. The minivan and the pacifica use the same engine but with an alum. block..

Hmmmm.... Might be interesting to see what the weight difference is between the two. Guessing that it's not that much since it's only a little 3.8L V6. I can say that after driving this thing for 3 weeks that it's got OK power for commuting and general traffic duty - nothing impressive, but I haven't felt like it was dangerously underpowered yet. It's seemed to take more throttle to get going some times and it has had to downshift on what I would consider small road 'rises' (wouldn't even call them a real hill) - leaves me wondering if it really has enough 'guts' to tow the rated 3500 lbs and even make it up a moderate hill.

I can see it now - twin turbo aluminum block/head 3.8L

 

my rubicon has the same engine as the minivan? I think I'm going to be ill. they should have stated with the 4.0 L

 

Other Jeep engines have been used in the Gremlin and the Pacer to name a couple....oh noes Companies use engines in more than one vehicle? Thats it..I am creating my OWN engine!...

End sarcasm

Times change..deal with it..
