300GDT yes it can be done

Post by John Green » Wed 14 Oct, 2015 12:09 pm

There seems to be quite a few myths around about fitting the OM617A into various bodies. Stories about there being no RHD W123 300D's and 300TD's because it doesn't fit and no RHD 300GD's for the same reason. A few of the OZBENZ members have already successfully debunked the OM617A into a W123 body myth and here for your viewing pleasure is an OM617A that we have dropped into a 1987 300GD.

It has a 5 speed manual box and has gone from being a slug to being quite nice to drive. (the picture turns around when you open it)

Hi John,

Congrats on the 617A conversion. As you know we have several 617A G conversions among our AGOA members (even one done by MB Australia) however some have found it easy while others have experienced problems with clearance on the RHS. The difference is in the model of 617A and in particular the inlet manifold. There are two basic versions being a high mount manifold and the older low mount manifold. Obviously it's the high mount gives the easy result.

Anyway it is good to see another 300GD being made in to a better highway cruiser. Well done.

John Kenny

John,

I have to strongly object to the grill ... I'm pretty sure, the PCP (political correctness police) is already on its way ... :laughing6:

Great work, how much horsepower does it have?

Just out of interest - asking for a 300GD owner who has pondered the turbo thing but doesn't frequent here - but where do you find an OM617A - what cars had it in them - how hard are they to find?

Hi Craig,

AFAIK in Europe only the S123 station wagon; elsewere other W123 (even the Coupe) and W116 / W126.

300D turbodiesel + Aircond - Yes it can be done.

If your 300GD has air conditioning, there is no reason why installing an OM617A would prevent your air conditioning from working. Just remove the A/C compressor from your OM617 before removing it from the vehicle, then bolt it onto the OM617A once it is installed.
If it was working before the upgrade it should continue to work after the upgrade.

This is how I did it in my 300D about 5 years ago (give or take a few years, - I did not put a date stamp on MY upgrade.

Regards,
Tony

Can't see how the inlet manifold is the issue. The only point that is close to fowling is the exhaust manifold where it is very close to the engine mount. It does fit just, but we trimmed about a centimeter off the top of the stud on top of the engine mount and took a little off the alloy leg, just to make sure.

After being told it doesn't fit by several people including Derek who made up his own manifolds, I can't see what the fuss is all about. Maybe if someone used an OM617 950 engine from a W116 300SD it is an issue?

Not using the original York compressor as fitted to a 300GD as the turbo plumbing is in the way, and also not possible using the R4 compressor as used on the later 300D/TD as there is not enough room between the sump and the chassis rails.

I believe you could do it, using a more modern narrow compressor and a custom mount. It would have to be something like a Denso 10P15C and go under the power steering pump.
