Yeah, it seems to be a monster, but not sure a TJ frame would hold up to it.

Almost 400 lb-ft of torque is pretty rough on a small frame like they have. We put a 427 in a Toyota pickup once, the torque buckled the front of the bed.

I would guess they are either reinforcing the frame (which would incidentally take all of the needed flex out of it) or doing customs.

Looks really expensive to do this

From Turbo Diesel 2.8 CRD in a TJ/LJ solved..... - Expedition Portal Forum

Burnsville Offroad was finally able to pull off a full conversion where everything works. AEV was the first to do this, but they will not do another. Burnsville was able to pull it off by swapping the dash cluster and steering column from the Liberty. They also had to swap in a set of JK axles in order to get the ABS speed signal that the computers need ( for cruise control if I remember correctly ). Burnsville also pulled off a 6-speed manual conversion with the Rubicon 4:1 transfer case for you gear grinders.

As a note.

-Full backspacing JK wheels would pull the width down to the same as 17" AEV Pinters on TJ axles.

-AEV was able to pull off this conversion by using a small interface computer between the liberty computers and TJ dash cluster.

-Hotwire also did one conversion but was missing the ABS signal so the Cruise control would not work and they had some automatic transmission control glitches.

-Green Diesel Engineering is also doing some very interesting work on reprogramming the engine control computer.



It looks extremely complicated and maybe needs pros to do this.
Don't have the money for anything like this or the know how for that matter. I wanted to do it all myself. Maybe I need to look into 4BTswaps.com It may be just a bit easier and cost friendly.

Do it!

In a perfect world I would have one TJ with an L33 for a crawler, and an LJ with a diesel for an expedition rig... Add the genright Safari gas tank... that would be sweet.

To Veterans past and present, thank you for your service!

Yea but I see that it would be a very difficult swap but I just may attempt it. Won't worry bout the steering wheel from the Libby cause yea the Sahara does have cruise I could live without it. I will keep researching and maybe try to attempt this by summer of next year.

And it will be cheaper than a 4BT cause I won't need new axles

They are probably using the Liberty steering wheel and column to get around the Sentry key.

There are other ways to do this though.

You can swap the Liberty ignition cylinder and Sentry key module in to the TJ steering column.

Yea after reading up on this 2006 Jeep Wrangler TJ Unlimited - Common Rail Diesel Engine - 4 Wheel Drive & Sport Utility Magazine

I see this in there and you sir are correct

The steering column, instrument cluster, and 75 percent of the wiring harness were all incorporated into the Wrangler. That way, the sentry key that was originally with the Liberty crossed over to the Unlimited enabling all of the VIN protected modules from the diesel donor to be retained

Check out some of the Land Rover drivetrains. I've been considering a 200tdi swap, but there are some issues to get around.
