Is this an LJ?

My TJU Sport identifies as an LJR. Do I get a front dana 44 now?
You'd need different motor mounts. And transmission mounts.
Federal EPA swap law. It isn't strange at all. Not widely enforced but it is the law.

Which tranny does the Magnum bolt to and work with, Rick? I think with the Gen3 Hemi, you are better off swapping in a 545RFE as well since the ECU runs both.
This comes up at least once a month..... Yes if you live some place that doesn't do emissions checks who is ever gunna know? Most likely no one. But if they ever decided to start requiring emissions testing where you lived then what? Here is the PDF from the EPA on engine swaps.

A 44RE or 46RE but they do have the same bolt pattern. There is a kit out (EXPENSIVE) to mate a Hemi to a 46RE. And one to mate a 545RFE to a Magnum but then you have to run a stand alone for the transmission.

To be clear, when you say new motor mounts, are you talking the rubber mounts or are you talking about welding in new mounts in different locations? I don’t weld, but I do damn near everything else, and my brother who is a professional mechanic is a wiring god. This would add a lot of cost but I might consider it.
You would have to move the motor mounts or modify them at least. Without measuring where the motor mounts are located at IN THAT JEEP as people place them in about a 3" range and then having one of the guys with a Hemi here measure theirs it'd be hard to say.
As for wiring if you were doing the Hemi swap you'd be better off IMO to buy a new TJ harness & a Hemi harness to build you a new one. If the Magnum swap was completed then the TJ & Dodge harnesses are already blended and trying to undo all that would be a PITA.
As already stated you could keep the Magnum and just register it some place that doesn't have smog/emissions testing. If you don't have it where you live then I wouldn't worry about it but know it could bite you in the ass.
Bellhousing pattern is similar enough to work right? I guess the problem would be crank pattern and pilot hole? Not to mention electronic issues if not using an rh trans?
Yes the electronics are the hard part. From my understanding the bolt pattern is the same. There is a flex plate for either swap now.
Not exactly related to this guys swap but i saw some stand alone controllers for the 545rfe when i was doing a little 2.8l-3.0l CRD daydreaming. 800$ though.
Yep, they aren't cheap... I had looked at swapping a 545RFE behind my Magnum but it ain't worth it just for one more gear. I'm not sure what is required on the 46RE behind a Hemi. The 46RE is still more hyd controlled.
Registering out of the county isn't as easy as you may think. AZ nolonger alows you to use PO boxes, you have to have a physical address. This is where the tags get sent. I also don't know what this would do to insurance. Don't get me wrong, I would totally do it if I had someplace to register the jeep. But then there is always the risk that the whole state will adopt emmission inspections and Iwould be screwed.
I hear this all the time, but how does that explain the 'LJ' on the frame tag?
Yep, that is why when I did my swap I kept it smog legal. WA now doesn't do smog tests but they use to and could again.
And yes you have to play games to get it registered. My ex FIL use to use my address to license his motorhome as my tags were cheaper. Bit him in the ass when I got divorced from his daughter.
Wrong screenshot, I want the one from a dealer's computer order screen for anything LJ related.
