does anyone know were and what I have to buy to make my m104.98x 3.0l doc 24v engine a stroker, I´v heard that I can use the crankshaft from om606 engine and more than that I don´t know :/

Everybody needs TURBINA! is better 1200 hp

Pistons, rods and a cranks shaft.

What crank you want depends on what you want the stroke to be. It is much easier to find a 3.6 AMG engine than a 3.5l diesel crank shaft. And cheaper. You will have to have the diesel crank machined to fit and the 3.6 fits Also rods and pistons to match.
It would actually probably be easier and cheaper to buy a 3.6 engine and aftermarket fuel injection system than to make a 3.6 from a 3.0

Anyone have the weight of these engines. And how was the weight measured. Fully dressed or how striped.

I do not remember exactly but it is around 600 lbs if I remember correctly and I would imagine that is long block. Accessories would vary from model to model.

I've never actually seen one on the scales. It's not light but probably not as chubby as Whipple's estimation. The OM606 is listed as 575lbs dressed.

If anyone has a digital scale in Indiana they'd let me borrow I'd be more than happy to weigh my spares.

Cant be 600#. M113 = 413 fully dresses, M120 = 654 fully dressed. There is a reason the 0-60 times of the R129 SL600 and SL500 are about the same. M117 ~ 500#

I would like to get a good number for the M104 to add to this thread.

I might be a bit high. I really was just estimating. But remember all those v8 engines ad v12 are aluminum. And the m104 is and iron block. I can carry a bare aluminum block with one hand. I cannot pick up a bare iron block at all..

I kind of figured that. I debating to myself should I make a 107 subframe to fit a 104. I'm kind of loosing the debate with the M113 at just over 400#. But the 104 has plenty of interest for people that want to turbo or supercharge. Lots more room to work with so I would be interested in getting an accurate weight.

I remember changing a Ford FE 390 intake manifold from iron to AL. That netted a 66Lb savings. But then that manifold was about the size of a 104 block.

They made the sl with the m103 in it, if memory serves me. Should just be able to buy the right subframe if it is even different. Could just be a different oil pan. Have you checked the EPC?
Why not the m113?

As you say the M103 was available in the Euro 107's. And it was available with a stick. With the 560SL subframe the 103 engine is a bolt in. Not sure if the M104 is just as bolt in. Might be.

But the subframe I made for the M120 should also fit the M113 and M104 since it mimics the r129 dimensions. It may also fit the M119 but I believe that engine may be to wide to be practical. So the goal is to make 1 subframe that fits all three engines. For all I know I may already have that subframe but additional tweaks may be required to accommodate each engines particularities.

I will probably post a build thread on this when I get a car to do this work on.

From what I recall, the M104 in a R129 / W202 have the same pan with a more forward sump where a M104 in a W124 / W210 has a sump pushed back 2" or so.

Early Euro R129 could be had with a M103 , USA market got the 3.0 M103 block with a M104 style 24 Valve head. ( the intake ports are different than the later EFI ports )

All the pans and interchangeable and the pickup tube on the oil pump goes to different lengths and angles to match. You can bolt any inline 103,104,603,606,613,648 oil pan to the engine. So you can do rear sump if you want. Engine mounts all bolt on in the same locations. So if one of these engines fits in the car. All of them do. Of course layout of other things may be different. ie intake, exhaust etc.
Also the 648 has a different bellhousing pattern so the bottom of the pan does not bolt to the transmission. You can just leave it or section it off and weld on from a compatible pan.

The M103 has a single row timing chain and the M104 double. A 104 pan might fit a 103 but not other way round due to timing chain clearance at front of pan.

At least the 97 M104 has 2 places per side to bolt motor mount aluminum wings , I cant speak to the others.

I just meant the pattern was the same. I was going to make a m104 4matic w124 once. I never tried to bolt one together though. I would not think it mattered. Oil pump goes out front anyways. Easy enough to check.
