Euro OM617 Specs. 617.95?

I've got an '84 W123 sedan that was brought over from Germany. It is normally aspirated, so I was wondering about the differences between it and the 617's on U.S. versions. For instance, does it have the oil jets for the pistons? What was the output of this motor? I've seen claims that the Euro motors ran higher compression? It has over 350k on the (broken) clock and is leaking fairly badly from the rear main, but I don't want to throw away a jewel - - replacing it w/a U.S. turbo motor. I'd like to put a little, bitty turbocharger and intercooler on it to give it a little more top-end.... Any thoughts??

i have one like yours. we rebuilt it. it doesnt have the special features such as the oil jets and special pistons which you reference. internally it is identical to a 240d, infact, we used some 240 pistons in rebuilding it. the only obvious difference to the us 300d is the injection pump which has different injection line routing. i dont know if it has differences which enhance performance, my opinion is if there are there not very significant. my advice is if you want a turbo motor go get one and rebuild that. the turbomotors are different in many ways and are much more robust. the cranks are different, the pulleys and balancers and oil pans. if you sit them side by side the differences are many and very apparent. the non turbo motors are very nice though and are nice to drive, expecially with a stick. mine will go 100 mph and accelerates nothing like a 240.
