My engine is that I thought was a 617.952, in infact a 617.912. So the turbo that is currently in it had to have been added. All of the papers I have on the car indicate it is an 85', however this is not possible as the 617.912 was only made until 81'.

My big concern is how well the engine will hold up over time with the added turbo, as I know the two engines are difference until today when the MB dealer got the engine number off of the engine. I also found out today that it is Grey market, imported into the US, but unknown of when.

I have had the car for 7 years and didnt realize there was a difference. I have put about 80,000 miles on it and have never had any troubles with the engine or turbo. I have taken it to the dealer for maintence(valve adjustment today) and they have never once mentioned that the added turbo will cause any problems. I have had no problems with the engine itself but am not concerned that they may arise.

I am not sure what to do exactly. Do I keep the turbo on or do I remove it? This is really depressing as I have been lied to somewhere along the line. Should I try to sell it and get another, although it would be like giving up a child to me, or do I keep it? So many questions are running through my head right now, I dont know what to think. I am gonna sleep on it and see what tommorow brings
