Just ask @cosine he knows!
Kenneth, great thread, since you're a helicopter mechanic I'm sure this was well within your scope.

For us shade-tree mechanics I'm sure it would be a bit more "adventurous" :)

How much are you in for with this swap if you don't mind me asking??

Yeah, it could be more adventurous for others, but anyone that has common mechanical abilities could do it. I’m in it about $14,000, the kit shipped was $10,200, the engine was $3,000 and I figure $800 more for various parts/supplies, fluids, and A/C recharge. His kit price has went up $1,500 since I purchased it, with the 392 coming out I can imagine these kits will reduce in price greatly. It will give people a cheaper option to swap then to purchase. They will if they want to stay in business that is, especially if Mopar ends up throwing a Hellcat in them in the future.

Great thread for us capable and more cost conscious. Hopefully as the JL matures we will see more builds like this. Thanks for sharing!

In your engine swap how much electrical can you get rid of? We’re you able to get rid of the stop start etc? Thanks.

The start/stop function is 100% disabled, that’s about the only permanent change, it comes with its own Tazer JL with special programming to keep the bad data codes from throwing a check engine light. All the standard functions of the Tazer are the same.

Does the Hemi shut off cylinders going down the road?

I am thinking that if I burn up the 3.6, that a hemi swap would be the logical choice.

No it doesn’t.

So I’m wanting to do this swap on my rig too! I’ve been in contact with America’s most wanted 4x4 and they told me that the transmission is a weak point on our jeeps. I was wondering if you’ve have any issues since doing this swap?

I haven’t had any issues, I would imagine the 6.4 & up would require a beefier trans. I believe even America’s Most Wanted also uses the factory trans for the 5.7L. Last I checked Northridge 4x4 listed the 5.7 kit installed for $22,000ish, I can’t imagine at that price there is a trans included. They also don’t advertise the 5.7 kit on their website, I just happened upon that listing when I was on Northridge’s website one day.

I just checked, it is $30,000 now and states it uses the 8HP75.

Damn I wish I would have hoped on it when it was still at 22k! I’m not sure why it needs the new transmission!

Have you been hard on it since the swap? How’s the MPG’s?
I’m never hard on my vehicles but I’ve also pulled a 8.5x18 trailer through the Colorado mountains with no problems, which is usually pretty hard on a trans. I have about 15,000 miles since the swap, with no issues.
