Just thinking out loud. What other non-rover engines can be swapped into a `04 D2? I hear that 5.0 Mustang injectors fit ours and offer more power and better fuel. Does anybody know of some other choices for an engine?
What engines (non-rover) are ok for a D2?

I know someone here was working on dropping in a Mercedes Diesel. With enough time and money you can really do what you want.
MB diesel may seem like a good candidate because it was likely sold state-side in front of ZF 4HP22.
That said, I know of people who tried to install one in a full-size jeep (more underhood space than in a Disco), and reported it very difficult. Oil pan clearance was #1 issue.
On the subject of MB engines, the 3.2 V6 (not straight six) from late-90s should be a better fit. A little less low-end torque, but similar power to 4.0.

Your real issue is going to be the electronics. Do a search, lot's of info. The DI is the logical choice for a engine swap, much simpler. Most people buy the DII for the added amenities (read complexity). Sure, I'd love a diesel, but I want EVERYTHING to work as advertised. Not saying it can't be done, but hey, time and money is what it's all about. Good luck.

Why do you want to do an engine swap? Especially for another car engine? Other than a TDI/diesel conversion, I think its a bad idea. You have to consider what parts/electronics are interchangeable, and modify what isnt. Unless its drop in ready, its not worth it. If you want better gas mileage, but a prius. If you drop in another v8 you might get 4mpg better. Its not justified by money/time/stress.
Thx guys. I love my truck but I am having some issues and If I have to look at getting a engine for it, I would like to see what other options I have. I don't have all the time and money that I would like, but I was thinking if a Ford of Chevy or another GM engine would work and run all the things (increase of power and better mpg) that I have on the truck. Oh and if is going to have less problems that would be be better.
Hate to be the bearer of bad news, but here it is right between the eyes. Limited time & money for a non-Rover engine swap? - FORGET IT!!! This starts to fall under the "if you have to ask, you can't afford it" rule. Sorry, but that's the reality.

I've only seen 1 non-rover replacement of a D2 engine, and that was Roving Beetle from this board... there is a writeup of what he had to go through.
Basically unless you're willing to spend a couple of months and $20k at least, forget about it... if you're concern is the issues you are having, they are most likely minor compared to the issues you'll have trying to fit something else into a d2.

If you would consider a diesel, how about sourcing a Td5 unit from Europe?
Otherwise, I think a used 4.6 will be your best bet.
If there was a (relatively) simple V8 alternative, we'd all have swapped over by now!

I don't know. After driving the 4.0 for a couple of years, I have to say that it is a damn good engine, at least in my 96. Has 160K on it and runs with 40 PSI oil pressure, burns no oil, smooth as can be and great power for only 4.0L. It's also a very light engine at only 300 lbs, so in terms of power to weight, it is bigger than it really is. The 4.6 would be even better in this regard. Runs forever if you take care of it. Only seems to lack enough power sometimes and gets bad mileage because it is asked to pull 4500-5000 pounds or more around, and in vehicles which have the aerodynamics of bricks. With the right gearing it can do just about anything. So, considering all of that, one could even say that it is a marvel . . . .
Runs forever? I don't think so. Runs for as long as you don't drop a liner, blow a head gasket, or have an oil pump failure.
And the D2 is really not that heavy. My Dad's Yukon with a 5.7 does the same milage as my D2... while he's towing.

Forever is a figure of speech, of course. But the problems you describe are only for the engine at the end of it's tooling lifespan, i.e. D2 engines. It has served as a good, reliable engine in Rovers since the 1960's. A motor doesn't stay in service that long without being a good design. It's a classic among motors . . .
On the 5.7 Yukon, more torque equals better fuel mileage, and the 5.7 is also a classic engine as well.

MB engines were mated to MB transmissions. The BMW and Volvo engines were mated to the ZF transmission.
I think the BMW engine would be fairly easy in relative terms. The issue is you probably wouldn't gain much except reliability, power output wouldn't be much different with the added weight over the Rover mill. Fuel mileage probably wouldn't be much better. The reliability probably would be, but the cost of a low mile engine and replacement parts kill the economic gains if there were any to be had. Not to mention the cost associated with swapping it and getting it dialed in. Fix the Rover engine.

You can get a used 2.8 M52 for as low as $600 with wiring and ECU. Power would be about the same but you can supercharge the BMW engine for about $4K and get 350hp out of it reliably.
BMW parts are cheaper than Rover in most cases by the way.
