I've been watching too much Youtube lately and got the bug to drop a 6.4 into my JKUR. It looks like there's the AMW kit through Rubitrux and Dakota customs makes a kit. Anyone know or researched specific differences? Other kids to consider?

This looks like a do-able DIY for myself minus how to deal with the A/C freon. I guess I have a shop suck it out before I disconnect that stuff and get it recharged when it's complete?

What's the parts cost in total with a new 6.4 crate motor and all the extras? The conversion kits look like $10k. Engine is probably $10k with the extra parts. So is that right I can DIY for $20k or have a shop do it for me for $30k? I'll gladly save $10k have a fun project if that's what it comes to.

Initially I was looking at LT1 swaps but there's so many owners on YouTube with videos about errors, check engine lights, or things not working. I don't want to start a food fight, but that does worry me.

Is Dakota not just Burnsville offroad renamed?
I thought there were a bunch of posts somewhere about BOR lying through their teeth regarding "this has never happened before. EVERY other kit we sold is flawless, must be something you did"

That answered a lot of my questions. Now to keep watching all his videos. Looks like Jeep Speed is a good source for swap parts so far. Looks like probably $15k if I run my transmission and buy more stuff like the full exhaust kit, etc.

I just had a Dakota Customs 6.4 with the 8 speed kit installed in my 2008 JKU. Dan was great , there were s few kit shortages that he fixed immediately(next day air shipping) . the 8 speed in the earlier JKs had some PCM issues , he had it fixed very quickly( got a new PCM shipped next day for a Saturday delivery) . Over all I'm super happy with the kit and the jeep it freaking rips. since i was spending money i also upgraded the axles. I went with the dynatrac serious performance kit. 44 up front and the 60 in the rear , 4:88 gears and ARB lockers. before you ask why not 60/60 combo, thats a huge jump in price. I spent $9k on my axles and reused my wheels, the 60/60 combo is $16/17K and then 5 new 8 lug rims.

In my experience the axles are more important than the power plant.
What did the engine/tranny cost you?

I did the total install kit witch included all the labor . The engine and transmission were brand new maps units that were provided by Dakota Customs. He has an in with a local dealership and gets them at a discounted rate . But I don’t have a number for you on the engine and transmission price.

Okay. There was literally no dollar amount in your response.
For me, I know if I ever needed V8 power in another jeep, I'd be better off to buy the $100,000 392 from the factory.

Dakota Customs 6.4 8speed kit + install $35K
Dynatrac serious performance 44/60 combo $9200
Teraflex Delta big brake kit $2500
pair of 1350 drive shafts $1000
PSC Big bore box only $900
ARB twin compressor $600
SPOD $600
Total spent for the build just under $50K
I thought about the new 392 wrangler and you're correct $100,000 is about what you will spend. If you want to play you have to pay..

I have spend half that on my build and my jeep should be just a little but more capable than the new 392.

Lol 1st post here but not new to the game, just
To the JK platform. My previous was a 6.0 YJ with a ton of mods. I went wheeling with Dan from Dakota Customs about 11 years ago in Brainerd MN. He had a jk on 40’s and a big hemi in it. It was awesome. I haven’t seen him since but hey good guy and knows his way around Jeeps. He had another there that was a 5.7 hemi too. That was also set up nice. I’m picky as f*** about my stuff and I’d definitely buy from him.

I would concure with that. There is just so much to putting a V8 into a jeep with all the electrical and emmisions crap. My jeep does not need to go fast, my Porsche is for that ane you could pick up a nice Porsche for what people are dropping on a V8 swap. Actually the 4XE has roughly the same specs as the 392 and would be my choice if I were to ever get a new jeep, which is highly unlikely. That being said I am working on a engine swap in old green and it is not a V8

For me it was worth it . My jeep had been paid off for years and I really like it . I taught my son how to drive in it , taken it all over the place on family vacations , no way i would trade it or sell it. The price for a new 4xe or 392 are super high and by the time you add suspension , wheels & tires you could be well over the $100K mark . The 4xe are cool and stealthy quite when on all electric. The new 392 is pretty fast too and sound great. Mine will out perform both off road in and a straight line( not really the point for a jeep but man its fun) . The swap has been dead nuts reliable and im super happy with it . I had a local shop perform the install. They had it in and out pretty quickly so no real hassles . Yeah a 911 would be faster on a track and maybe to the next stop light . But a 392 Jk is a lot of fun for sure .

This one is by far the most credible source on the cost of a hemi swap:

JK gear and gadgets - My Jeep Wrangler DIY hemi seap cost how much?

If you haven't watched that yet, do it now.
The hemi is physically large and quite a bit heavier than an lt engine and lower tech. It might integrate easier, cooling would be more challenging also with minimal real estate under the hood. I would hate to ruin my jeep with any poor conversion. Lots to think about with any of these 8 cylinder conversions.
