Most of them were 2.2's. There were very, very few 2.0's in countries like Hungary, Albania, and Greece, but none of them were turbo equipped.
The "turbo" blocks are more heavy duty, have piston squirters from the factory, and are much more common.
There are also a few 2.3-something versions available in commercial vehicles.
The one I'm having built is being sleeved for the relatively common OM606 pistons and rods, like we would have had stock in a '98 or '99 E300D Mercedes.
The crank is from a previous generation OM601 2-liter, which were pretty common in Europe, but never imported here.
We got a larger version of the OM601, a 2.2 liter, in the early ('84-'86 or so) 190D's.
