I had no clue they made the xj or here called Cherokee mostly with a diesel. I wonder how much to get one imported as that should be in my jeep
They did, sold everywhere except North America. Not the most reliable of engines, because of the independent heads on each cylinder they have a habit of cracking around 150.000 km mark. Heat builds up after you shut off the engine and at one point bam. I cracked 3 and then bought 4 new heads from an aftermarket source, which claims to have improved the design (originally there are 2 glow-plug locations, aftermarket heads have only one). And everyone using it has not had overheating issues. I've also given the ports a good de-burr and very mild porting.
better yet how did you find us?
more pics/info would be swell...
I want a VNT (1756vk) on this thing, I work in software development so building a controller is a piece of pie. Looking for VNT ideas I stumbled upon tdiclub but over there people aren't too much into IDIs, like over here...Here I am
More info you say...Bosch VE pump, with LDA (or AFC), with electronic timing control and mechanical throttle, push-rods, gear-driven cam and IP, 115 Hp stock, 300 Nm (sorry, I will convert to lbs ft tomorrow), 28mpg high-way, poorly intercooled, restrictive exhaust.
The bottom-end is interesting, crank bearings sit in big circular aluminum retainers, which sit in a tunnel in the block. So the bottom of the block is actually enclosed and once the aluminum expands it sits tight in the block tunnel.
Ecu controlled idi interesting!
Only post 97 models are fly-by-wire, I want and don't want one of those
The engine in question is a VM Motori diesel, made in Italy. Unfortunately, they were never sold with this engine in the U.S. or Canada, which is where most of the people on the forum happen to live, so most of us don't know much about them.
If you speak French, you might try the French forum, where there are probably more people who live in countries where these were available.
Jeep also offered a Renault turbo diesel in the Cherokee, engine from commercial vans in Europe, in the late '80s, and these were sold in North America. Unfortunately, they're really rare.
Correct, it is a VM Motori engine
Renault J8S, very cool engine, all aluminum, light, a good friend of mine has a Cherokee with that engine. The engine was installed in a lot of applications, even sedans like the Renault 21.
Anyway, back on topic...biggest reason I'm here is to learn and find answers to some questions like what exactly does the full fuel screw do? Increase injection duration or just quantity? Do I need bigger injectors for my 180-200 crank horses goal? What should I do with the 7-8 psi drop across the intercooler?
It's an IDI, it should be close to VW IDI's in how it responds to mods
Please excuse the dirty engine bay
My attempt to solve intercooler heat soak, works for now, it dropped EGTs by 100F cruising. No difference in full-boogie
I wish my girlfriend was this dirty:
