Has anyone put a mercedes diesel in a 928?

There is/was a 928 in the UK with a 2.5 BMW diesel in it. IIRC it came about because the owner had a 928 with engine failure and a written off BMW with working engine.

I think it is an interesting idea. You can make crazy power and torque with a diesel. If there is a donor car out there why not?

I actually wasn't thinking about a diesel to increase power. A person could go down that road though and there are sites dedicated to modding mb diesels for power. If I was going for power I'd use a different mb than the w123 one I was thinking about. Probably an 1987ish one. Here's one drifting:
even the older turbo diesels such a w116 300sd or w123 can be modified fairly easily. For big power though a big turbo etc would be needed.

The 617 is likely to be too tall, for this reason, it's hard to install into an R107 body Mercedes , let alone a 928.
The 603 is a straight six so likely too long.
In my opinion, a total waste of time as I owned a 75 300D barely got 23mpg out of it. My more modern V8 engined Mercedes does better and can get out of its way.

I have though that vw tdi swap might work. Yeah it probable does not make sense to someone that drives 20 miles a day. But averaging close to 4000 miles a month, makes one think mpg instead of hp.

That's interesting, is that city mpg? I always got right around 32mpg on my previous and current MB diesels, the exception being the 240ds (which are as slow as a turtle) which got around 40mpg. But those are highway numbers. Some of those cars weighed 4000lbs.
I agree with the poster above that it's hard to make an economic argument for such a conversion if you don't drive it that much. I would be more interested in the challenge of "can it be done?", to make a somewhat environment friendly 928, and to have a reason to save an early 928 that would otherwise be doomed. On the enviro side, my city hates cars. I love cars and have had numerous gas guzzler v8s and some v12s. It would be cool to have a car with some style that fit in with my city's enviro-culture. I wouldn't do it for that reason alone but it would be an interesting side benefit.

I know these OM617 motors like the back of my 928...give me a shout if you are seriously considering it. Google what the Swedes have done...here's a tickler.
I wouldn't do such a thing to a 928 though...
woooohooooohoooooohoooooo!!!!

No, it was a mix, mostly my drive to work which consisted of about 15 miles of highway and about 5 miles of city. I must say that I had my foot in it all the time but I don't see how one could drive it otherwise.
I'm not sure what the axle ratio is on a 928 but I can imagine that one with a diesel engine would be horribly slow, unless it one of the newer common rail designs. But then there would be too many electronics to integrate to a car with too many electronics.
IMO, horses for courses, Keep the 928 for what it is, a fast GT car and rock the diesel for your commute to work if you feel like it.

I was wondering if anyone has done this. I occasionally see engine-challenged 928s for sale and old MB diesels are a dime a dozen around here. I'm nearing the end of my BMW sedan pickup conversion and was thinking about this as a winter project.
I know back in the day people used to transplant engines pretty easily (f.e. a ford with a chevy v8). They would have a place cut the driveline from the original rear dif and cut the driveline from the new tranny and weld them together.
Can something like this be done for the 928? I believe the 928 uses the MB auto tranny? Does that help? Would be very slow but good on gas. I would keep my other 928s, this idea would be more for one that would otherwise go to the crusher.
