ok, I did the swap here's what I had to swap
1: the engine wiring harness
2: the alternator
3: used oil pans from the c43
4: used throttle body from c43
5: swapped knock sensors over
6: motor mount arms
7: ac compressor, 55 motor didn't have one. don't know if you can re-use
My motor was from the w209 2003 clk 55 with the evo spec motor. will post dyno once I do it to see what improvement there is over a normal 55 motor. I hope this clears any confusion for future swaps

time out. if you had to swap oil pans then there is a very good chance you need to also swap oil pickup or else you are starving the engine of oil despite the oil level being fine. it's happened to another member here and perhaps cm60k can chime in with more info.

That was my biggest concern, if the 4.3 oil pump would have enough flow for the bigger motor. I ended up using the 5.5 pump because i thought it would be on the safer side. can you provide any more info about the other member?
Just checked the EPC and oil pumps have different part #s. I doubt that MB would make a different pump flowing more oil as both engines are not much different in size. Only difference is the pump pick up point due to sump design.
A closer look at the EPC shows that the E55 has the same oil pump reference # so guess you are good to go
Starting to doubt anyone has done this swap with the w209 engine. This oil pump is killing me, I cant use the c43 pump because it wont bolt to the motor properly and i cant use the clk55 pump because the pickup is too high and the 2nd pickup is sucking air because this car NEEDS to have the c43 pan with only the front sump, w209 pan has a rear sump that hits the steering rack. will try oil pump from w208 but i dont know what i will do if that doesnt work.
Just incase anyone wanted to see the difference. there is a fraction of an inch difference on the bolt spacing for the pumps, they are very close but dont fit.
someone on this board has claimed to do it. i cant find the thread, but he also claimed a few mods and a lot of HP. he is not a frequent poster so even if i did find the thread i doubt you'd get a quick response if a response at all.
are you saying that the bolt holes do not line up? put the pump on a press and drill them out.

The idea now is to extend the clk55 pickup tube lower and plug the 2nd pickup holes but if that dosent work i may have to look into making the c43 pump fit. It was popey24 i believe, and I drove the car a little bit with the clk55 pump on. holy **** its awesome, i need to feather the pedal in second now because 1st gear is useless and 2nd gear is also close to useless. Theres so much power down low i cant wait to get this up to speed and hear it scream at the 6700 redline.
Wanted to post some photos of the fitment issues we had with the oil pumps, we fixed the problem but i wanted to show you 100% can not use c43 pump with w209 engine

isn't it amazing what a difference it makes? I was expecting it to feel noticeably more powerful because on paper it's not that big of an increase, but holy **** the car felt twice as powerful. It radically changes the car and makes me question MBs judgement for not shipping them all with this engine.
the e39 M5 is remembered as the first ever super saloon but a w202 C55 would have given it serious competition.

My first impressions were to how this car sounded like something from nascar and how much power down low there was. What a shame these cars didnt come with the 55 from the get go.
Hey Sulaco. The donor car was an '02 E55 with just shy of 115K Kms.
Hey Im also doing this swap from a 02 e55, can I use the trans out of the e55 as well? information is not clear to me from what i read so far on the online forums.
Yes you can with some modifications regarding the park mechanism on the transmission and swap the propshaft flange.
Thank you!! I will do research on both these mods, I hope someone has something written on it, I read previously that the TCU would have to be changed but Im glad it doesn't. If you know of any threads, please let me know. Thank you!
So before reading this thread, I honestly did not have any plans on doing a 55 swap, I believe not even a full week here and I got myself a motor lol Anyways I bought it from a Bimmer dismantle shop down in ATL. I have been in contact with them and they have provided on the information I needed from them, but when matching the engine code (number on the rear right side of the block] to the vin I was provided, I see that they are not matching up when I decode the vin. using this tool here http://carinfo.kiev.ua/cars/vin/merc...u=trud3e860z5n
I have uploaded the pictures that I have of the engine code and of the engine itself , I know that they are difficult to tell apart c43 vs c55, but I want to make sure, that this is in fact a 55 motor. Is there a way to verify the motor by engine code (Reverse look up?) This is what i make of the engine code 113 984 60 016 765 3 or 8 1 0 5 << underline is a total on only 4 digits
any help would be appreciated thank you.
