EPA legality....in theory if not from the factory that way,, even if the engine is ok, could be a big problem........titles and such could be affected..this has been thoroughly hashed out int he Land Rover world and in the end, if not factory with the engine, it can be a huge problem.

in Michigan you can build what ever you want on the frame of a vehicle as long as it was a factory frame at one point and it can be road legal with lights and windows
exactly... Having a hard time swallowing that state regs might stop you from modding your vehic. any way you want. That's the premise of hot rodding which is widely accepted in California of all places!!! If your state stops that, then you live in the wrong state. I don't worry about that in WYO..... Go Pokes!
Emissions go by vin. If it is higher than what it is supposed to be from the factory it fails. Not sure what the process is to have it legally switched over, but most people who build have gearhead friends that can inspect it for them. I don't know anyone who went through the process of doing it legally, but they all have stickers.
Complete rebuild axle/engine/everything swap in progress:
Parts already gathered for assembly: 2001 Ford 302, 1990 Mustang GT 5.0 ECU and wiring, NP435, NP205, Pair of axles from 04' F350 SuperDuty (Sterling 10.5 Posi rear, Dana 60HP Front-Both Disk Brakes 3.73 Gears), 37" H1 Tires, 9" lift TJ Coils for 2 link conversion in front, Stage 2 Clutch Kit, 3 Row Aluminum Radiator, Chevy Astro Steering box (4" front Stretch), XJ Rear Leaf Springs (6" Rear Stretch), and lots more.
Looking to swap in the new 3L VM diesel into my 05 Unlimited. Any word on cost/difficulty/tranny compatibility? The more and more I look into it, the more i want a diesel. 4bt/Cummins seem like way more trouble than they're worth. 3L VM Ecodiesel fits in the Ram 1500 and the Cherokee, shouldn't be too hard to fit in the Wrangler. Word is it's a stock option on the '16s. Any way to get them now, and cost?
The cummins weighs in at over half a ton fully dressed, plus fluids! Not to mention the firewall modifications needed to stuff the longer than stock 6 cylinder under the hood. I would imagine you will need a custom radiator and electric fan setup AFTER hacking the firewall up for an addition 8" of clearance.
I am sure people have done it, but I can only imagine it handles horribly....I think you would have to have a bucket of cash burning a hole in your garage floor to justify this swap. You will end up with full sized axles under your rig and a jeep that is twice as nose heavy as it was ever intended to be. I would imagine you need to do some frame reinforcements to deal with that added weight.
When it is all said and done what do you end up with? A jeep that won't do well offroad because it is so nose heavy, a low reving engine, and something that has the torque to pull a house down and a wheelbase WAY to short to tow anything.
Head over to 4btswaps.com and read around a bit. The 4bt gets all of the attention because it has the cummins nameplate, if I were to do the swap, I would go with the Isuzu 3.9l turbo, it is a smoother running, quicker reving engine, and it is really under valued. I think if you keep it in the HD 4 cylinder range you can swap in D44's from a FSJ and have a stock looking jeep with tons of torque that can still do what it was designed to do from the factory.
The OM617 from the mercedes (5 cyl. turbo) is also a good swap on a budget, there are kits to hook it up to the AX15, and its size lends itself to not having to replace the entire running gear of your jeep.
Good luck either way, I am not one to talk people out of projects, so if you read through the cons and still want to do it, keep us posted on the progress! One of my fav. swaps is a 7.3l international diesel in a Scout 800....and I am sure it suffered from most of the same cons listed above.
The OM617 TD is nice swap, just a tad heavier than a 4.2 and fits nice under the hood. Its not huge in the power department, but they are bullet proof, run forever, and get decent fuel milage. This is mine, 99 % people think it's stock when they look under the hood.
