OM603 into 300SD
I have a spare OM603 engine and I was thinking about doing a swap a few questions
-Do I need a 300SDL transmission or will my 300SD tranny fit into the om617 -engine mounting the same or diffrent???? -will it fit??? It looks like the engine compartment is the same size. My om617 engine will go into the 1974 240D with the 4spd and the om616 will undergo rebuilding and will be stored for future projects.

The OM 603 will not bolt up to the SD's original transmission! The OM603starter is on the left/driver's side and the transmission originally connected to the OM 617 engine has its starter on the right/passenger's side!

So with the starter on the driver side will the tranny and starter be able to fit w/o modification to the body??? Will the tranny bolt on to the mounting?? What about the drive shaft same or diffrent.

The starter resides alongside the engine block and does not extend into the transmission tunnel so it wouldn't be an issue. The starter hump barely extends into the tanny tunnel so it is very unlikely it would be an issue. The OM 603/tranny may use a different tranny mount and the tranny mounting plate may need to be repositioned forward or rearward. Original drive shaft may be too long as the OM617 is shorter, the tri-lobed end flanges of the drive shaft may be incompatable with the flange on the OM603/tranny, the flange on the tranny should be able to be swapped with the one from the original tranny. Driveshaft diameter may be different but not an amount that would matter. |

I bet overall it would not be that hard to do. Especially if you had an SDL to grab parts from. You might need one half of the SDL driveshaft.
I don't think I'd want a 603 instead of a 617, the 617 is awesome.

Have you ever driven a 603?

Imagine how fast would it be when its 800 lbs lighter and 2 feet shorter. You know, i wish i could go to Stuttgart Germany and convince them to use a 6 Cylinder turbodiesel in a W126.

Yes....still prefer the 617.
I'm not "against" the 603....but the 617 is undeniably tougher....and the low end torque off the line is awesome....and the sound it makes at 3000-4500rpm is awesome, especially with a straight pipe! In fact, all the sounds it makes are awesome with a straight pipe. I like the turbo whistle at idle, sounds like an engine 4x its size. I am even confident that my SD could pull a better 0-60 or drag race when vs an SDL. I'm open to any challengers.

I really doubt the extra 4" of car weighs 800lbs. In fact I bet the difference is minimal.

At my local salvage yard there is a complete nicely running and driving 150k '87 300D and a running 91 350SDL, but its doing its rod bending thing. Both may be a good source of parts for you.

all i need is a head (previous one cracked) but the engine was totally rebuiled by PO and ran fine, tranny, driveshafts, 300SD transmission Flange, possibly a Holset HY35 turbo and a back up car its going to be a long term project. what's wrong with the 1987 300D?? is it wrecked?

The SDL was 0-55 in 10.4seconds, I doubt that the 617 can top that. Power is power unless there's a huge gearing disparity, and the SDL probably doesn't weigh much more than the SD with 617. Tougher? There are people on this forum with 500,000+ miles on 603s, if you mean which one can last longer when overheated, ... you're probably going to win that one, but why would you try? I think that they're both great engines, and most of the 603 was tough enough to live on as the 606 with some changes and a 4-valve head.

Well, with my old setup on my car I was able to pull a 12.1 second 0-60 on a slight uphill grade......I'm betting with my new 2600rpm torque converter that it may have shaved off a second or two. I'll have to do some tests and post back. Maybe a video. It certainly FEELS like it moves to 60+ a lot faster....it feels faster from 0-35 than the 300E.
It just seems like the 603 has more weird and expensive issues than the 617....lately it seems like a lot more 603's have been having issues here on the forum than 617s.....

Doesn't the SDL have a lower final drive than the SD, anyway? That would probably make the 180 ft lbs seem closer to the 603s 201. Maybe... (defending the 603 )
