Anyone on here done a 6.4 HEMI swap on their 2 door JL? How’s the experience/reliability? Looking at possibly doing a swap on my 2 door JL. Enjoy having the smaller size but would be sweet to have a V8 in it instead of the four cylinder. Wonder if the 392 might have lead to some shops giving a better price on a doing a swap?

Dakota customs did a 2dr that was for sale on their website awhile back. Looks like its sold. You might need wheelie bars with that much power in a 2dr 😄 (and the wheelie bars will kill your departure angle.)

I guess no one ever “needs” a Hemi in any vehicle … but do you really need one in a 2 door? While mine is stock, the 3.6 really moves my 2 door, especially when it is just me and not loaded down. How fast do you really need to go?

I guess if you have lifted your Jeep and have bigger tires, you may have need for more power, but that is a lot of grunt for such a small ride.

I want to do a 5.7 in my 2dr. 392 would be cool, but the additional cost doesn't seem worth it to me.

I was hopeful Jeep would offer a factory 392 2-door when rumors starting circulating in earnest last year about a V8 Wrangler...I thought briefly about an engine swap but quickly decided the best option for me was to just improve the performance of my 3.6 (4.88's, Mopar CAI, Borla Touring cat-back & Edelbrock Supercharger) and call it a day for now...

I have only personally known three guys who have done (had done) engine swaps and all three turned out to be nightmares...Now there are a few high end shops who turn out quality products (America's Most Wanted 4x4, RubiTrux come to mind) but unless you have time, skills and patience for DIY-hell I am having a hard time finding time for mods as it is, lucky enough to have a top-flight shop local or willing to ship your rig to one of the few top shops-I would take a pass.

Best of luck if you do go the Hemi swap and please post pictures and review!

I had a 5.7 in my TJ. It was fun.
My 2 door JK has 1200 horse. It's pointless :)

Honestly, a 6.4 would be really fun in a 2 dr on 37's with a slightly stretched wheelbase and low COG (w/ proper shock setup). It's probably where the 'fun' meter is maximized. Once you start going supercharged etc you have a lot of other shit to deal with, especially in a two door.

- Low end torque
- Snappy throttle response
- Still easy to cool.
- No power adder so less to go wrong and deal with.
- Retains factory fuel system

The only negative on the 2 door is the gas tank size.

I'm not familiar with Jeep engine swaps but I do know that any engine swap in a vehicle that did not come from the factory with it is going to to need a lot of future wrenching and repairs.

I’m planning on keeping my 2 door JLR for a very long time. So if the day comes when it will need a new engine most likely it will be the 392 as its not really that much more than the 5.7

Agree there for sure — I have a core 6.4 sitting and waiting… may just build it into a 447 need to weigh pros cons. Plan is to create a 2 door LJ clone eventually.
