Diesel Engine Replacement---any Out There

[BLKXJ33]

Does anyone know of any diesel engines that will fit in an xj...without too much major modding. Thnx

 

[Genster]

maybe a 4 cyl cummins, but i dont really know much about this. id love to be able to drop a 5.9 cummins in an XJ or CJ!

toyota has a 4cyl diesel that they used in the landcruisers, only available in canada though....you could try a diesel car...maybe a mercedes???

There's always the POS 2.1L peugot/renault turbo diesel that came from the factory in the late 80's or there is also a newer turbo diesel used in XJs overseas. I think its much more powerful. They are coming out with a diesel Liberty. That engine would probably fit.

Ford is supposedly looking for a new diesel for a 2005 or 2006 F-150...

right now they use international

the 4 choices ford had are:
detriot diesel
cat
john deere
cummins

i have the most experience with detriots, and i like em.....but john deeres are also excellent engines...all 4 are really....

Volvo used a 6 cyl version of the VW Diesel. Its an inline 6 and looks about the same length as the 4.0l and not tall like the Cummings.
Nissan also made a 6 cyl inline Diesel, the Air Force uses them in Jeep Tugs. These are a strange looking Jeep. They have a CJ looking hood, but with Square headlights mounted in the fenders. The back is cut off and there is a heavy steel rear that has the tow hooks. They use a 1 ton rear and the front axle is just a hollow tube, no diff. However, they do have a Auto trans and a T-case, but it seems to only be used to get the low gear. The tugs top out at about 25 MPH.
This would be my choise if I were to go Diesel in an XJ, but finding one may be hard. Airports may also use them.

I just found one of the Jeeps on E-bay, here is the link:

I'm told by some that the 6 cylinder Volvo diesel is not one of the great diesels out there, and actually is quite similar to the Renault 4. I believe this was the product of a joint VW/Volvo/Renault venture. Of course it would still be pretty nice if you could find a good one. They had a turbo 6 version in the 740, I think.

BAck in the 70's INternational Scouts came with a Chrysler/Nissan 6 that was supposed to be pretty good. In its later turbocharged form it could haul a long-wheelbase Scout around pretty quickly. But it was huge. Very long, with an enormous bellhousing. I've heard of one of these being shoehorned into a Jeep SJ, but I think it would be hard to get it into an XJ.

I keep looking at the Mercedes 5 cylinder 300D engine (happen to have one languishing behind the barn....)and thinking that that would be a pretty neat fit in a Jeep if you could figure out how to mate it to an AW4. In its turbo version that would be a pretty nice powerplant, and the old ones are about the only engines around these days other than Jeep 4.0's and Chevy 350's that still have a proper cast-iron head and chain driven camshaft.

If you can find one, Dodge trucks in 1978 came with a Mitsubishi 6cyl diesel. They mate to a big block chrysler trans. They were 120hp.

VW diesel like alot of thew Zook Guys do, I think AXIS conversions was selling the kits, but I don't think they still sell them.

the L6 cummins is to big and heavy.... the toyota 3B is to heavy... the 3B and H55F (tlc 5speed) together weigh in at about 1200 pounds shipped.

The Mercedes 240D late model has about 75hp and can be tunned to a little more. You can turbo it but at low boost. The 300D is a 5 cylinder diesel with a little more pwer but if you going to go thru all th trouble then way not use the 300TD that can be tuned up to 200hp . A 240D 4cylinder diesel weighs about 450pounds. The 300TD with the extra cylinder is a little more.
I happen to own and drive a 240D. I have the last year they made the for the North American market. It has decent power but is slow. Gets in the mid 20's for mileage. The 300TD is just under that. Some people claim 30+ mpg with a 240D. I just had mine smogged a couple months ago and it came in at 7% with a limit of 45%.

Another option might be the SD33T. But they are hard to find. They are a nissan diesel and came in the International Scouts towards the late 1970's. Hard to find. You have some transmission options with this engine. The LD28 is another way to go but doesnt produce the power and it can be turbo'd with the gasoline conterpart turbo.

There are the volkswagen diesels. The older 1970's diesels will not make any power for you. The earlier 1500, 1600 diesels wont do anythin for you in power. Turbo kits were made for them but they do not turbo well. One reason why they stopped making the kits for them. the 1.6TD isnt a bad engine but i wouldnt use one in an XJ or MJ. I would consider the 1.9TD as it can make some decent power for the XJ and MJ and still get you better fuel economy. The 1.9TDI is the best choice and it can be chipped and injecter swaps. That engine will easily produce 150hp and 300ft-lbs at the wheels on a dyno. The Volkswagens they came in weight at an average of 3500 pounds. The wagons weigh more and they still have ample power at 90hp and 149ft-lbs and still get good mileage. The 1.9TDI can get about 50mpg. Even chipped it will get the same mileage with an average of 30% increase in hp and torque. They are a light weigh engine and in my opinion would make an XJ or MJ seem like it has a gasser in it but would see the better fuel economy. We happen to also own a 2002 Jetta with 1.9TDI and average in the mid 40's. If I dont have a lead fot I can get 50mpg or higher. It smogged in at 0.1% out of 45%.

Out of all these choices the 1.9TDI will generate the best power and the best fuel economy. The cummins are nice but they are not as light or as efficient as the tdi.

Volkswagen races the TDI's in long distance and endurance racing. they race them side by side with the gas engines. When they open them up at the end of a season they show virtually no wear...

brb... family calls.

Check out the 4 cyl Powerstoke 2.8....here's a customers rig that we just did a Galvy chassis swap (1997 D90)and a Safari Gard 3 Link. He's sporting the 2.8 literes of love.

i've been thinking about the diesel option too, but am looking toward the liberty crd as a donor, it is similar to the 5cyl in the dodge sprinterr van and mercedes, as well as euro grand cherokees, pt cruisers, and caravans. the liberty setup will provide just about eveything from engine thru transfercase, already bolted together. otherwise i'm looking at the ford 6.0 powerstroke drivetrain, engine to axles, for my wrangler tj.

I have also been considering a diesel conversion. The cherokee XJ was available with a 2.5 VM/Detroit diesel, almost everywhere but North America, until DC finally cancelled the XJ. The 2.5 mated to the AX15. So, the good news is that off-the-shelf parts definitely exist for a drop-in conversion. The 2.5 has recently been substantially upgraded to Euro 3 standards with a 4V head and hefty boost in torque and hp--more torque than the 4.0. This 2.5 engine is now available in the non-North American Liberty with a manual tranny--I guess DC doesn't believe North Americans are capable of shifting gears. Visit the Detriot Diesel site for info on this engine series: 3SA444.

6 Liter Powerstroke? Man that would be a pretty tight fit!
