The 6.2L diesel was a good engine as long as you did not get it hot. I had an '88 Chevrolet 4x4 farm truck with the 6.2L diesel. It always had fuel tank, tools, parts, etc in the back and pulled trailers a lot. It had 286,000 miles when the odometer broke. I drove it four years after that. Never went into the engine. I sold it several years ago and saw it on the road occasionally up until a couple of years ago. I guess it finally gave up the ghost. Or maybe the rest of the truck finally rotted away around it. The body was well on its way to falling apart when I sold it.
Iknow this is a diesel swap thread, but if you could get a standalone ecu to run it, a 3.5 ecoboost ford motor/tranny might be a nice swap.

The answer may not be a V-8 at all. A diesel inline six from Mercedes might be a good choice. There has been a lot of interest lately in the five cylinder OM617 amongst the Toyota Minitruck crowd. With a standard output of 125 hp and 184 lb ft (250 Nm) it probably wouldn't be enough engine for a Land Cruiser, but maybe the inline six cylinder Mercedes OM606, 3 litre, would fit the bill. The OM606 is rated at 174 hp and 243 lb·ft (330 N·m) with what looks like a not so difficult path to increase to something like 240 hp and 440 lb ft (596 Nm). According to the Wikipedia page for the Mercedes OM606 it has a dry weight of 463 lbs (210 kg). Donor cars would be late 90s, early 2000's E class automobiles. Bendtsen’s Transmission Adapters offers an adapter to pair the Mercedes engine with GM manual and automatic transmissions. Advance Adapters has the parts to match those transmissions with the Land Cruiser transfer case. If this all seems like too much trouble, check out this video of Nissan Patrol vehicle powered by a similar engine from another German auto manufacturer.

Holy crap! We are truly living in a golden age. That said, there's something positively creepy about a V6 in an 80 series.

Wow, engine weight is 417 lbs.
- 365 Horsepower @ 5,000 RPM
- 420 lb. ft. of torque @ 2,500 RPM
That's how much the 6.2 V8 weighs with 420HP/420TQ for way less than the Ford which has direct injection (read TROUBLE!).
There is a lot of support for the 6.2 V8 conversion as many people have done it.
But again, those are not Diesel choices the OP addressed.
The OM606 cannot simply put out that much power without major upgrades. Yes you can take it up to 400 HP, but it requires a boat load of very expensive upgrades.
A simple ECU tune would get you 200HP/300TQ for less than $500.
240HP/440TQ is a bit of a stretch. Not accomplished with the stock turbo.
One more thing. Those engines only came here to US for 2 years to be specific 1998 Mercedes E320 TD and 1999 Mercedes E320 TD. Nothing else.
Of course one can import an engine from EU.

Yes, the 6.2 makes a lot of sense when considering options for repowering a Landcruiser. Just last weekend I was looking at a Vortec 5300, 5.3 litre aluminum gen III Chevy V8 for my 1989 4runner. The asking price was $1200. There are dozens in my area with similar pricing.
When I say, that as gearheads, we are living in a golden age, I have the LSx in mind. They are abundant, they provide a lot bang for yer buck and community support is unparalleled.
I got a 3.0 straight 6 twin-turbo diesel with a 6-speed tranny in my garage. 350HP/480TQ with all the emission crap on it. Take those things out and you get 360-380HP/500-520TQ out of a 467lb motor.
Strongly considering this option if it can be done, and done in a way to be able to register the car as a diesel in CA. Mission Impossible right? Depending on how much I am willing to spend on this conversion I suppose.

OM606.. get rid of the ECU and slap a mechanical inline pump with 8mm elements on it, maybe a HX50 and big ass IC. Ta da, +500 HP/close to 1k Nm..
Of course newer OM642 (V6 3L) or OM648 (I6 3.2L) would not be a bad choice at all. "Simple" chip tuning will get you closer to 900Nm of torque.

Ummm... Nope. The original hp and tq figures listed of 170/240 are correct.
You won't be using the ECU so a tune is out of the question.
A OM603 mechanical injection pump is needed. You can get the modified 8mm element pump for apx $1600 last I checked which includes shipping, or buy the elements and Alda for under $1k shipped and have a local diesel shop install them. A 7mm element pump and stock turbo converted to standard waste gate operation can do a max of 278bhp the stock turbo being the limiting factor. A 7mm pump and upgraded turbo can get you 350bhp 8mm pumps can easily pull 500bhp anything above requires internal mods.
The turbo model came in 1998-1999 E300D
I'm not sure if you guys at the other side of the world got different power setups/year range but OM606's are used in different models, starting from 1997 to 2000? here in EU. 177hp/330Nm are the specs IIRC.
603 pump is they way to go indeed.
But hey, MB also offers a 4.2 V8 CDI if it has to be V8 diesel engine

The
The 5th gen V8 engines use direct injection. And if you've got the money to buy a new crate motor and everything else to swap it in then the rather small price difference isn't going to be a problem. At least with the Ford there is a factory made control pack that's made specifically for swaps in to other vehicles.
The problem is fitting the Ford engines to other transmissions.

There is no reason to keep the stock transmission with any diesel or V8 swap. The gearing is bad even for the stock engine.
A 5 or 6 speed transmission makes a lot more sense to have with a new swap.

Getting the ecoboost HP level's worth of heat out of a 3.5L block makes me nervous. On a ford sedan? sure. But a truck that requires much more constant hp to push it down the road at 80mph? Let alone towing? Similar power numbers to an engine with 80% more displacement and most likely much larger cooling capacity..
Plus.. Intercooler packaging?
And as has been mentioned, direct injection is a quick path to problems like intake port and valve deposit problems.
It dawned on me the other day that stuffing an aluminum 5.3L in and adding a low pressure turbo setup (mostly to compensate for altitude..) wouldn't be too difficult if you could get the charge piping plumbed up efficiently.
But yeah, not exactly a diesel v8.

Not in the 80 yet, but this is my dream swap. As the prices plummet for these BMW's, I might not sell the car but keep it for a powertrain swap and then scrap it.
Really quiet.
3.0 twin turbo 350HP/480TQ
Transmission gear ratios
1st....4.17
2nd...2.34
3rd....1.52
4th....1.14
5th....0.87
6th....0.69
It would work perfectly with the 80 stock diff ratios at 4.11, keeping the engine in it's intended power band.

I have been reading/researching this same swap for some time. The aftermarket and current producers as well as a good machine shop have taken care of all the 6.2/6.5 bugs from what I can tell. I spoke to a couple guys that did this swap and they said the end product was a smooth running diesel cruiser. With the parts availability it seems it would be a low cost diesel that gets good mileage. If taken care of these motors I am finding go 300k. Plus you could always swap an nv4500 with the motor, now if I could figure out what the guy in the video did...
