Hello all I am Jason from Hungary (Budapest)

I have currently 2 Mercedes:

a 1991 c124 230ce (m102) 5 speed manual
a 1984 w201 2.0 190 4 speed manual

Both cars are in the process of slowly getting restored and different engines as the 190e will be getting a m103 and hopefully boost and a better trans to suit it. This would be the simpler of swaps as everything came in the 190e 2.6 so this would not be my problem.

My questions arrise for the c124.
After alot of searching and searching I have not found a proper answer or things getting off topic.

I would like to place a M104 in place of the m102 as the m102 2.3 is very very laggy in the big c124. My choice for the swap would be a 3.2 or a c36 3.6 motor. My car is currently a manual and I do know I would need the a couple of parts and do know from my understanding that non of the m104 engines were drive-by-wire.

m104 hfm 3.2 or 3.6
better trans?
engine wiring loom
all motor accessories

my car is not a auto trans car so i could maybe source a manual trans 3.2 motor from a manual w124 and make this swap easier as when i read the forums benzworld, mbworld etc etc i see people are wanting to swap auto for auto and need the extra ecu for the trans as the motor ecu talk to the trans ecu.

Would this swap be a little simpler for a manual trans merc?
What else would I also need to acquire?
I know the swapping the motor part is the easiest part and wiring being the more difficult part and want to stay away from aftermarket ecus and do not want the cis m104.

I have also thought of getting an early m111 2.3 kompressor motor as I do believe they are not drive by wire but I am not sure and again very little info. I will be doing this conversion myself so as much info and know how from the more experience with this converion would help.

Future plans after this swap would be a 6 speed (if the c36 motor is done and not the 3.2) If I do the 3.2 then I wil be duplicating what brabus did later in the future.

Thanks for you inputs.

3.6 are hard on head gaskets without a turbo.M104 would be a good choice or a 500

easiest swaps can be done if you have a complete front end donor car. Note that you will also need the suspension, the brakes, and the differential from the car you are swapping from. Thats cause your car is a 4 cylinder car and all those parts are different.

The suspension and brakes part I understand very well.
I do have 300ce 24v H&R springs and bilstien shocks that will be installed and currently sourcing brakes from either a r129 or w124 500e.

At the moment I have a 300ce differential but I am also trying to source a 2.3 16v w201 diff (hard to find hard to find here in Hungary)

I can easily get a 3.2 with engine control loom and ecu but is there any other wiring looms or computers I should take from this car. The wrecker wont sell me the complete car but i am sure I can get any other parts if needed to make this motor work.

Not to interested at the moment in boosting the c124 as this is more of a touring car for me while the w201 will be my sort of track thrash car as I am swapping the m103 in it boost will follow with that but I would like to finish the c124 first.

So the list follows as of now from my understanding:
m104 (3.2 or 3.6)
trans? (maybe if I decide to not use the m102 5 speed manual)
differential
engine wiring loom
ecu for the engine (hfm motor ecu)
suspesion (already have)
brakes (sourcing now)

Would I need a traction control computer?
Is this built into the engine ecu?

I know there is a forum member that has swapped a c36 motor and bits into his 91 300te but his car was an auto, would I need less bits as I have a manual?

Anyone feel free to chime in thanks!

the electric transmissions need computers to run,and traction control would need computer and sensors.I'd go with a older m104 without all that crap.however harness will need changing if not chaged.
