Engine Swap

[truittkeeler]

Hello All,

So I have zero experience with the liberty jeep. My friend's mom has a 2002 liberty with a blown motor. I have a 2008 rubicon that I did a 5.7 Hemi swap on, meaning I have the original 3.8 V6 and transmission out of the rubicon. Is it possible to swap the 3.8l for the blown 3.7 in the liberty? Thanks for all your help in advance.

No. Sorry. 3.8 (60 degree V6) is totally different from the 3.7 (90 degree V6) Even if it weren't the reluctors in the motor would be too different for the 2002 PCM. Lots of write up on using 2005 & newer 3.7 in 2002-04 jeeps and Dodges

Far as I know you'd have to have all the wiring, PCM, and body computers to swap a different engine/transmission in the Liberty.

But maybe somebody knows better.

Could be done, anything can with enough money but like mentioned , with all the computers etc now days, almost impossible to do
Worth it? No way would have more into it than a good 3.7 would be.

I mean this in the nicest way possible but the 3.8 is ****** compared to the 3.7. At least from what I've read.

Too bad they don't make a crate to fit... guess the demand is just not there. A crate diesel would be awesome...

From what to OP said he has the 3.8 engine and transmission out of a wrangler cause he swapped a 5.7 in to it (BTW pretty cool) I'm not sure what all he has for it far as harness and pcm.
The 3.8 ought to fit KJ frame just the electronics is a PITA.
