300D Non Turbo To Turbo
 

I was just wondering if anyone could give me some info on how to turn a 1977 300D non turbo into a turbo, what parts need to be changed? Is it possible?

I started to do a search on this site http://www.mercedesshop.com/shopforu...=1406992&pp=30
there is some info but I dont know what exactly you need so I hope this helps.

i have access to a turbo 300d parts car if you need any thing.
i think the turbo is good shape too.

bow2no1, thanks for the offer, it is my brother's mercedes, I will ask him if he is interested. thanks again

no problem..
the junk yard i go to is crushing right now.
they will be all summer.
the 300 turbo i saw was in the back of the yard. to it might be a month maybe before he gets that far back?

The time, money and effort spent on converting the OM617.912 (Non-Turbo 3.0) would propbably total out more than the cost of an OM617.952 (Turbo 3.0). For about $1,000 you could have a complete running OM617.952 (Turbo 3.0).

There is more that just the turbo between a turbo 617 and a non-turbo 617 engine. The turbo 617 have a heavier crank, different exhaust valves, piston cooling, and a larger oil capacity due to the piston cooling (7.0qt. vs. 8.5 qt.). These are just the differences that I know about and I am sure that there are more. Certainly you could bolt on a turbo and the related manifolds to a non-turbo, but I would question engine life.

The 617 (whether turbo or non-turbo) is a great engine. I don't care if I have to adjust hard lifters.

ABSOLUTELY AGREE
:U::c:

i agree also i have a 3.0 turbo engine but no turbo if you are interested

Mercedes
 

I have a 300D also and was wondering how i can get the anttena to go up if it won't without pulling it? If your push it back in it goes down by itself though... Do i need a new part or is it something i can fix?

it also smokes from under the air intake. is that heard of or is it the asbestos stuff burning under the hood?

It is very easy to do, but definitely not recommended as the non-turbo motor is not built to handle the heat and stress that the turbo motor will. Swapping in a turbo motor, on the other hand, is even EASIER, and HIGHLY recommended if you must have a turbo.

Just out of curiosity, why do you want the turbo? Is it time for a new motor? Does the original motor run just fine? Most of the power issues I've seen with the non-turbo motors are either normal maintenance related (or lack there of), or simply due to improper transmission detent adjustment. I have bought several of these cars, and the 240's, because the owners were sick of them being extremely boggy, slow monsters. Either the transmission shifted too soon, not allowing the motor to wrap up into higher rpms, or the filters were trashed, and it wasn't getting enough air/fuel. Some simply needed to be driven! When you just tinker around town in an old diesel, and never get it out on the highway and see higher sustained rpm's, you get coked up. Carbon builds in the exhaust, in the manifolds, the head, on the valves, on the glowplugs and injectors.
