Well I purchased a 2.5 turbo from a 93 300d today. I got a tandem pump for the sls that bolts right on. I will be starting in a couple of weeks on the transplant. If everything goes smoothly then I will be selling my 617 turbo motor. It is a euro model with no egr and the adj waste gate. Any idea what it is worth?

Congrats (or condolences?) on Biting the Bullet!
Please document the install and take lots of pics as you go. Things like what electrical plug interface you have to do. This might be something others will want to do someday. I for one am subscribing to this thread now that your going ahead on the transplant. I'd like to stuff one in my W115 chassis
A running 617 turbo engine is worth as much as people are willing to pay. I've seen them offered for $400 and as high as $1200. It all depends on if they are low mileage or not and yes, there are a few low mileage ones still. A couple years back I saw a 1980 300TD (NA engine) with 110K miles on it at a salvage lot. I kinda/shoulda bought the steering box, it was really tight!
