diesel enine

[leftyatm]

Ok guys, i hear that some of the new liberties are equipped with turbocharged diesel engines. first of all im wondering if this is true and secondly im curious if it would be a direct bolt up or the amount of fabrication would be required in order to drop one in along with the tranny and t-case. But i mean how cool would that be? An xj with a diesel :-)

[OT]

This is a thread on another board and it's a swap into an Unlimited Rubicon, but you can expect the same type of installation in an XJ.

Damn yes that is badass. It looks good in the rubicon im sure it makes for quite an impressive rig. But beings that I like xj's a lot more! It would be sweet. IF they could make kits that would make the swap do-able that would be awesome. They could make some serious dough and it would benefit a lot. I'm sure a turbocharged diesel gets a hell of a lot better gas mileage than 16mpg!!

Actually, we have one, right now its getting around 20mpg, but thats mostly in rush hour traffic, I expect the mileage to improve when it gets broke in, typically diesels improve as they wear in,, gotta tell ya, I am real impressed with the little engine, its only 160hp, but its 300ft lbs of tourque, it does have a half second of turbo lag, but when it spools, it will break the tires loose,, I keep tellin my Ol lady, that if anything happens to her libby, that I am gonna swipe the motor for my scout buggy,, I hadnt even considered it for my xj, but it should fit in one without to much trouble,, I think wiring would be the biggest obstacle to that....

I've never driven a liberty diesel, so I can't knock it from personal experience, but I was watching some news show the other night on gas mileage (60 minutes, primetime, something like that) and they tested a liberty- got something like 10-12 MPG 50/50 city/highway. they used it as the poster child for overstated EPA estimates.

My mother-in-law has one and gets 20 in 4-wheel in the mountains, and 28-30 on the highway. 60 minutes must have been testing the gas engine. Its nice to drive too, and does pretty good in the snow so far.

[jeepsta]

supposedly you can take a TDI out of a VW jetta and it is supposed to be pretty much a straight swap. last time i was home i test drove a puberty with a diesel in it and it rocked. i dont know about gas mileage but it was way cool. heres a link for a grand cherokee http://www.canev.com/Jeep.html

I want more info on that industrial four celender izuzu moter. how much HP and torque does this motor produce?
see Isuzu 4JB1-TC, 2.8L turbo-charged and inter-cooled 4 cylinder
How dificult would it be to adapt to AW4? How much does it weigh? What type of fuel pump would be needed? Could i reuse the factory hard lines? What are the cooling requirments? Any input? Links?

82-91 Mitibishi montero's came with

turbocharged 2.5 L OHV Diesel I4 with 62 kW (83 hp/84 PS)

or an intercooled 70 kW (94 hp/95 PS).

In 1996, the Pajero was slightly restyled, and larger engines were introduced, and a 2.8 L turbo Diesel with over-head cams and 92 kW (123 hp/125 PS) was produced. sorry, thinking outlowd

[Fudd]

Those eighties 4 cylinders Isuzus ran pretty good, I had one in a P'up Got about 40 mpg and it ran rich (never figured that out) They're pretty gutless though. Those P'ups might have weighed 3k lbs and it took forever to get up to speed (even w/ 4.11 gears) They run forever though, a very tough little engine. It would be an interesting swap. It wouldn't be too hard if you just wanted 2wd, as far as a transfer case I don't know which side the diff was on the front of the Isuzus.

I would sherly wonto keep my np231j, but would be willing to ditch the AW4.

I've talked to a couple of guys who own those, you couldn't pry the keys from their cold dead hands!

You edited that post for grammar and I still don't understand it.

While in Albania this past summer, all but one of the XJ's I came across were diesel. It's not a new idea. Anyone have the specs on the overseas XJ's with the diesels and how they compare with the Liberty diesels?

[kyro]

Hi there guys here is some info on the Aussie Turbo Diesel XJ's

A read of the specifications creates the impression that the diesel does not seem too impressive being only 2.5 litres, with a power output of just 85kW compared to the petrol engine's 131kW, but its torque delivery of 300Nm is line-ball with the 4.0 litre engine.

The Cherokee has its fair share of comfort and convenience items; standard power steering, power windows and exterior mirrors, air conditioning, all-round tinted glass, remote locking, illuminated dual vanity mirrors and an impressive CD-compatible 4-speaker stereo system.

Cherokee now also has a compass, in an overhead binnacle above the interior rearview mirror, and in these days of mobile phones, and all their accessory kits, there is a power outlet jack in addition to the cigarette lighter.

But most importantly, what's the diesel like?

Oil-burners often have to be patiently coaxed up to the highway speed limit, but Cherokee's diesel is a surprisingly eager performer. Its modest power output is not reached until 3,900rpm, but all 300 Nm of torque are available at just 2,000rpm - the turbo is an early-riser and having so much pure `grunt' on tap so early in the rev range makes a power of difference.

At highway speed, there is no need to even think about downshifting to overtake - just a light squeeze of the throttle results in a surprising headlong rush forward.

And it really delivers the goods when taken off the bitumen. Jeep's "Selec-Trac" 4WD system is one of the more innovative types around, and it combines well with the diesel and its smooth-shifting manual box to make Cherokee a real `anywhere-anytime' vehicle.

In heavy sand, despite Cherokee's 2170kg weight, it simply churns its way through with the diesel plonking along and pulling like a bull in springtime. (And that was before I remembered to lower the air pressure in the tyres…)

For all you guys thinking about a diesel for better mileage (somewhat better - depending) Diesel is now $.45 cents a gallon more than 87 octane here in NEW England.

This is an MJ with a Mercedes Diesel in it.

[marcoleo]

Here in Italy most of the XJ are diesel the earlier with renault 2.1td, the newer with VM 2,5td; the second one has a very impressive torque. For both the versions is available the clutch bell as spare. You can just boltin.
English reference:
this version is the one installed on new cherokee:

This one is the one used on grand cherokee:

also the second one can be easily installed, just a bit longer, one cylinder more

[bajacalal]

Marcoleo, do you know what sort of bolt pattern is used on these engines? Will a transmission such as the ax15 5 speed or the aw4 automatic transmission bolt to the engine if it came of a 4.0 liter Jeep? Or does the engine have a Renault or VM bolt pattern so a different bell housing (front part of the transmission) need to be taken from a diesel Jeep.

That said, the diesel Cherokee engines are hard to find in the U.S., the VM is EXTREMELY rare but we actually have parts for the 2.1 Renault where I work and you could bring the engine from another country.

I believe the Mercedes diesel swap MJ pictured in that thread was destroyed by the hurricane (Katrina).

Diesel is on par with the price of premimum gas here. But it seems to fluctuate a lot, both up and down.

[marcoleo]

Hi bajacal, the diesel version were sold, in europe, only with manual trasmission; both the engine having proprietary bolt pattern so you need the diesel bell or adapter.
The renault is interfaced with AX5, the VM (300Nm torque), I believe the AX15, not sure because I owning 5 XJ with renault.
Anyway isn't so difficult to interface the engine without the proprietary bell, when I'd a willys I've installed an alfa romeo engine with just a frame interface between gear/alfa bell & modified gear input shaft.
All the Renault j8s series can be installed with minor modification, the original were j8s-814 & j8s-890, the average life is around 190000 miles.
In the last two year the price of diesel/petrol is become very near and higher, about 1.5$/litres; with diesel engine we are about 6miles/litres; never seen a fluctuation on the prices, just growing up every month!!!

Thanks marcoleo. Hey you installed an Alfa Romeo engine in a willys truck?! And built the adaptors yourself? That sounds pretty cool, do you have pictures? What kind of engine are you talking about anyway, V8, 6, diesel...?

I'm not exactly positive about this but I think the AX5 bell housings bolts up to the AX15 transmissions. That is of course if you can find the Renault 2.1 TD.

Around here both gas and diesel have been dropping after hitting a price around $3/gallon (3.79 litres) after the hurricanes. Diesel is usually less expensive than gasoline but right now the diesel price is higher than regular I don't know what the reason is.

[marcoleo]

unfortunetelly I don't have any picture of the work, was done 10 years ago and I've sold the willys to buy my first XJ.
Anyway wasn't a big work, the engine was the petrol 2000 4 cylinder in line (with V6 & V8 not enought space), just cnc machined a 1/2" iron plate with the holes for alfa bell & willys gear (a couple of bolt were not used and some holes having a V shape in order that the bolt head doesn't make interference with the connection) and increased the lenght of the gear input shaft to engage friction & flywell bearing.
Here the price at junkyard for 2.1 renault in good condition, is around 700$ and VM about 1000-1500$ there two main version, in the second one >1995, most expensive, some problem with head, water circulation and timing chain were solved by VM.
If you need I've some spare clucth bell for 2.1.
