Jeep JK 5.7L Hemi Swap

- The Hemi is in and finally done! Jeep has the power that it should have V8. I know a lot of people talk at about doing LS swaps but I like the idea of keeping a Mopar engine in them. Plus if you have to take it to the dealer they can still read it with their scanners. Hopefully this video helps those that are thinking about doing it to their Jeep. Definitely a must do! Thanks for watching and let know if you have ideas to make it look better for the next one I may do.
Wow! Outstanding!!
Nice video
Gracias por compartir, saludos desde Puebla en México 🤟
Looks a lot like my JSS Hemi swapped JK.
What fender are you running? They look good and it looks like they provide great coverage.
Bushwacker
I like your fender flares, where did you get them? Brand? Thanks!
They are Bushwacker fender flares. Think I got them from 4wheelparts. Have had them on there for over ten years so don’t exactly remember where they came from.
I have a left over 5.7 Hemi with a 65rfe from an SRT Grand Cherokee swap that I did. I bought a 2012 JK to put it in. I'd much rather use the 6 speed 65rfe than the W5A580 that the JK has in it. I just don't know if the JK Tcase will bolt up. To use the W5a580 I would need a bellhousing and TC from a Charger. The other consideration is wiring and ECU. I have it all left over from the JGC so that seems straight forward. Is there a way to know if my JK Tcase will bolt up to the 65RFE without taking it off and trying it?
I don’t want to miss leaded you on it so I’m not 100% sure. But if I remember correctly the transfer case from a 3.6 won’t work. Why I say that is when you do the 8 speed swap on a 3.6 then you have to source a 3.8 transfer case, I believe, but haven’t done one yet so can’t confirm The wiring based on my experience with mopar wiring if it’s seen a good amount of water and mud then it’ll probably have issues soon. You can buy the wiring harness from Hot Wire. I think that’s the name of the company. The computer should jest need to be reprogrammed to match up the JK. Which you can do with HP Tuner. Or you can get a hold of JSS and he can get you the wiring harness and reprogram your computer for you. He could also confirm on the transfer case.

@@segamodshop1498 Thanks for the reply! An 8 speed swap at the same time would be pretty cool. I'll have to look into that as well. I know Chrysler had to change the tub from JK to JL to fit the 8 speed but people have done it.
I know Jeep Speed Shop does the 8 speed conversion for them. When I bought my kit he didn’t have it all worked out for the 3.8 to hemi conversion but I believe that’s all they install behind the hemi now.
you need the wire harness for the truck hemi or it’ll always throw a code
or need a tune
If you’re asking if you need the harness from the donor engine, the answer is no. The one you get in the kit is built around the engine and transmission setup that your going to run. You get a new computer with the kit so as long at the engine is mainly stock it’s good to go.
where did you get the hemi from?
Bought it from someone off Facebook that bought it for a project and never did the project. Always seems like the best deals for them. And the transmission came for LKQ.
Have you ever had trouble turning on? I did the same and it doesn't want to turn on. has. new wiring and computer and nothing?
When you say turning on do you mean the Jeep turning over and running or when you turn the key nothing comes on at all, like dash lights and such?
@@segamodshop1498 exactly, when I turn the Key nothing come on.
Sounds like you have an issue inside your TIPM or possibly the ignition switch. I would start with the TIPM and make sure you got power where it needs to be. It is very common on them for the fuses to not make full contact with the connectors.
What year JK ? 3.8 or 3.6 swap out ?
2010 JK with the 3.8L and manual transmission
is the 5.7 compatible with stock transmission?
I can only speak for doing the swap in the 3.8l Jeep. And unfortunately the answer is no. You have to get either the 5 or 6 speed auto out of a truck. I think JSS does an 8 speed for it. But at the time when I bought my setup it wasn’t an option. If you can find a manual trans out of a Dakota that had the 4.7L they will work. But good luck trying find one. I looked for months and they’re already bought up. So someone may have one in their garage.
You CAN use your factory jeep auto transmission from the 3.8 or the 3.6. They use the same transmission. You will need to change the factory bell housing to the truck bell housing and torque convertor. The tv show Truck Teck used this same kit and reused the transmission and transfer case.
I just watched that episode and they reuse the truck transmission the 545rfe not the jeep trans.
How much was the motor ?
I paid around 3,500$ for it.
Now your Jeep can tick tick tick away😂
