Joking aside, everything in moderation. If you're going to twist the boost up to max and do long 90MPH runs in the desert, you'll probably significantly shorten the engine life. If you run the boost at the lower end of the range and would only need the turbo to help you out run the kids on their Lambrettas, and drive normally, it shouldn't be a major problem. Another interesting factor is where you are in the world. Denver and environs shouldn't pose a problem, the less dense the ambient air the better for this set up. Obviously cold sea level areas would have the opposite effect.On 4/5/2011 9:54 AM, Mark in Lakewood CO wrote:

All the turbo stuff will bolt right on!
TERRIBLE NEWS!
It'll blow up your engine!
When MB put the turbo on the OM617 5-cylinder diesel engine to create the OM617A, they also installed oil squirters to cool the pistons. THESE ARE CRITICAL! Without these piston coolers, the pistons WILL meltdown and the engine becomes a boat anchor. And an unwieldy one, at that.
These coolers can be installed on the N/A engine. In fact, there was a one-time poster (and still possible lurker. Stretch, you still out there?) who did just that on a 4-cylinder 240D engine, and added the turbo! It had something like 500,000 miles on it when he sold it still running.
Don't worry about compression. Fact is: The turbo engine actually had MORE compression than the N/A engine!
Do a search on the list website and you'll find plenty of information on why simply bolting on a turbo is a bad idea.... (Try "240 turbo" or "4-cylinder turbo" as search terms.)

Subject: [diesel_mercedes] Doing some R&D need your help
Hi guys
I just found my self buying a 1979 300d 123
and then I found a turbo set up all the parts are there everything off a 79 turbo 300D what's the chance I can put it on my car with not a lot of trouble.
Is there a big difference between the two engines? Please someone give me some good news. Thank you for any advice you could give.
Barry,
