I have found that the 3.8 Dodge Caravan/Chrysler Town and Country motors are less than half of what the used Jeep motor is. If I bought a minivan 3.8L from 2007-2012, would it work in a 2007 Wrangler? I figure I would have to swap some parts off the motors, but is it doable?

I should have included this...A local shop told me I could by their Caravan engine (2009) and they would change everything out and put the new engine for $600. I am considering it, but do not want to cause a bigger problem. I cannot find anything that says this works.

There have been two different guys in the local jeep group swap in caravan 3.8's to replace the Jeep ones. From what was said as long as the 3.8 is from a 2007 or newer the block is the same, then you just have to swap front covers, intakes and pretty well all of the external parts lol

Thanks, I might give it a shot. A $600 minivan engine instead of a $2000 Jeep engine will be worth a shot. Even if I pay the guys $600 for the swap, I am coming out ahead.
I dig it! :rockon:

Please update this thread with your results. As long as it's '07-up, you should be good to go (swapping the externals over, obviously).

I'm assuming my 1-gallon hamster habitat will shit itself soon, and I've noticed the "minivan" V6 (same-same) doesn't carry the cost premium that the "Jeep" V6 does.

I'm not too proud to save a grand on semantics :laughing:

well I guess I stuck my foot in my mouth, turns out the one guy had hydrolocked his and bent a rod. He just used all the internals in his original block and the other guy sent me this message on facebook "Hey man! No, it required some machining to make work. Some of the engine mounts are different. The rough bosses were there, but needed to be milled flat, drilled & tapped. The dipstick hole is also in a different spot. There was one other hole that needed to be tapped or something....can’t remember. I ultimately used another JK 3.8."

so Sorry to get your hopes up, I was under the impression that they both had made it work.

personally my 3.8 is tired and I'm gathering parts to do a L83/8L90 swap

Thanks, you saved me some headache. I am going to give up on this option. I went and looked at it but could tell there were more differences than just swapping external parts so I did not buy it. I told them I would do more research first and might be back later. This helped my decision big time.

Is that really all one sentence?

I can only imagine how excitin' it must be to have a used mini-van motor in your jeep.

Well I guess it was pretty stupid considering it the exact same motor for under $900 with 44k bought Jeep for 4K sold for $11k guess I’m dumb to put a mini van motor in a Jeep . Thank you just trying to save fellow humans some monies , on repair a poor quality engine, but so will pay 3k for a 3.8l Jeep engine that is the same as $900 mini van engine ... cheers 🍻!

It was more the sentence than the motor I'm sure since his dash cost more to fabricate that you spent on your whole ride

Everyone does what the can with what they got-you got a deal on yours for sure/enjoy

I'm pretty sure "bashing" is a bit of a stretch in this context. Kowboy was pointing to the incredibly hard to read details you provided in a streaming - long , non-punctuated , run-on sentence. That together with a little jab at describing a 3.8l replacement. No one is begrudging you for being smart about saving your hard earned money= that's awesome.

( kowboy also has a fully customized ,one-off jk w/ a massive V8 and no JK electronics , so he has some experience w the factory jk powerplant + it's strength/weaknesses. he didn't mean to hurt your feelings. he is asking you to use grammatical elements so his old , tumbleweed-and-sand filled eyes can understand wtf you are saying )

He bought it with the 6.7 already in it...
Which is now all shot to hell. Need me a new engine.

After readin' this here thread, I thought long and hard 'bout replacin' it with a used 3.8L out of a wrecked mini-van.

But instead, decided to replace the stroker 6.7 Hemi with a hi-po 6.4L Hemi. Should produce more power.

In the shop now and hopefully back on the road next month.
