Moving you to w201 forum.

 

I don’t think w210 would be the right forum for this but i changed it

 

Palli, you're in the correct forum. My typo error corrected (w210 ===>w201)

You're in good hands here.

 

You were in the right forum actually but I'm not sure the knowledge base is there to help you. Let's see .....

 

I think you meant steering box/column from a w201 (not W210) M103 is what you meant. I suppose that would work, I'm not sure why the 2.0 steering column is different than 2.3 or 2.6.
Basically, I think nearly everything under the hood would be swapped out in this case. True?

No i meant the R&P from a w210. Someone said on another forum that the stearing box is diffrently placed on the 2.0 and the best option would be a rack and pinion maybe its bullshit but i will find out soon 😅

And yes mostly everything will be swapped out under the hood 😁

 

The steering box is in fact in a different location on the M102 cars versus the 6-cylinder M103 cars. The secondary firewall and motor mounts are also positioned differently to accommodate the extra length of the M103.

It's not impossible to do at all, you just have more prep work to do than you would if you started with a car that came with the 2.6.

If local regulations allow, you could keep is a 4-cylinder and go for the M111K, and basically get a 2.3L, 16-valve motor, with a supercharger.

As in an m111.975, from an slk230?
What about the rest of the ignition and hardware for this?

 

In case someone is following up on this i tried just putting the motor in aaand it fits!!! No matter how i lean it back and forth the steering box is not touching anything, the engine mounts are in the correct place it and it has like a 2-3 cm gap from the starter. i dont think i need to do anything to the firewall.

 

One thing i forgot to mention, the sway bar and the skid plate needs to be modified but that’s easy peasy

 

If it fits, it sits!! Nice!

I think the M104 may actually be a bit narrower than the older M103, but I'm not entirely sure. I don't have both side by side to measure, and my M103 car is sitting up at our shop.

 

Are you doing some work to yours?

It could be that its narrower 🤔 a couple of other threads said that it would not be possible to put a m104 in where a m102 sat without changing steering boxes and whatnot and that the motor mounts would have to be moved maybe they were mixing the m103 to the m104?

It literally looks like they just took everything from the w201 and put it the same way into the w124. up to this point everything has fit, clutch and brake pedals just went in on the same mounts as before also the gear shifter and also the gearbox from the m104 fits onto the m102 engine.

 

Seen one in the "legends of the autobahn" car show a couple of years ago in Carmel/Monterey.
It may have even won the modified car category. So it definitely fits but I'm not sure how much work it took.

 

If it was a black 2.6, with gray cladding, that's John's car from the over on the rev. Has a black W201FTW vanity plate.

 

Most likely. Here it is. I have a 1 minute clip that I should post somewhere of all of the W201's as it was the 35th anniversary there that day including mine and others in this forum. I'll post that at some point.

 

Yup, that's John's car. He is an electrical wizard.

 

M104 or m103s can be put in m102 cars with the engine mounts from dkubus fyi. No chassis mods needed unless the rad support for the bigger radiator.

 

Hey man, I know it's not a direct comparison but I'm swapping my 190 M102 for a M104.99x (3.2L) and I'm just wondering if your 190E has come along great. I've gotten a bit discouraged as a mechanic told me that this swap is near impossible because I'm trynna fit an engine that requires a lot of electronics to a car that came with a conventional carbureted engine. Just need to hear a success story I guess.

 

holy resurrection batman ))) this thread is 2 years old ))
but nonetheless .. the mechanic did warn you correctly, the electric part will be the most challenging, but nothing is impossible, just depends how much time, money and expertise you are willing to invest into it, you will need the M104.99x from a live donor with all the electronics and wire harness and so on
