If I have my original '02 CLK55 with the M113 engine and the donor car ('04-'05 E55 or similar) with the M113K engine, I have all the parts I will need as far as the oil pump and upper/lower oil pans, correct? Its just a matter of changing things over as necessary?
I've seen references to "tuning" the engine once the swap is done. Does anyone know what this tuning involves? I understand the necessity of reprograming the ECU to get it to mate to the car/engine combo, but what sort of tuning is required on an ECU controlled engine with electronic fuel injection and timing?
I went to the EPC and pulled up some images for reference. There is an upper and a lower oil pan. Is the upper oil pan (#5 in the picture) along with the lower pan (#50) what needs to be swapped out when you say the crank case?
Here's the pump, just for reference. Looks like there is a pump (with the sprocket) and the pickup. I assume there are the two parts with need to be mix and matched.
Yes exactly both upperand lower would be the crank case you need to swap.
Also, parr of the pump would neet to be swapped along with the remaining part of the new engine pump.

Is the "tuning" refer things like a bigger fuel pump, etc.? or chipping the ECM for performance upgrades beyond the stock M113K?
It seems as if all these threads just die off. So here's my attempt to keep this topic alive. My own thread I started about doing this to my C55 after hydro-locking the Kleeman charged engine has fizzled too. Due to me changing directions, partially to this lack of generalized knowledge and living in a rural area. Now, I'm going the safe route on it swapping a 40k mile m113 back under the Kleeman which hopefully is just a plug n play after ancillaries are upgraded.
So now i'm in ownership of a 20k SL55 drivetrain wiring and ecu with no home. So like many of you, the CLK55 looks to be the ideal candidate for a hot rod. Lighter than my SL55 and less doors than my C55 which ironically run almost the exact same track times of 7.9 1/8th. Surely a CLK M113k tuned would be a great stable mate.
Anyhow, consider this a bump before the thread follows so many into obscurity. Why don't any of the tuners like Eurocharge make a kit to solve the electronic/ plumbing hurdles? I know its low volume but they already did the research and many of us diy guys can stick the lump in the hole, we just need the details handled.

I'm all for knowing more about this myself. Like you're saying, dropping the engine in is no big deal. Its the specifics to make it run. Are there members here we can reach out to for input....that would be willing to share some info?

Reason: mispell
1998 C43 w/ 55 swap Wavetrac LSD and 6-Speed manual
I have the two oil pans and oil pump available for sale if you would want to prep your K engine while keeping the CLK on the road. You could then sell the complete N/A engine to a C43 owner wanting to do a 55 swap. I also have the CLK55 engine mounts, CLK55 throttle body, and CLK55 engine wiring harness available along with a bunch of general M113 parts (valve covers, intake, flex plate, timing cover, etc.).
I want to continue to throw out data and ideas so that we can as a group make a relative data base of our knowledge to see if we can combine knowledge to make m113k swaps doable. I have contemplated this swap into an earlier chassis too, essentially a MB hot rod, but AMG powered not LS. I think a m113k powered E coupe or e500 would be too cool or light weight 190 evo inspired machine. Anyhow here is an option to the transmission hurdle to using the great 5spd in an older chassis. Certainly there could be an issue in 100k mile useage without the wear compensation of the OEM TCU, but with less shift overlap maybe we'd see less wear, lol. For THOSE not aware of these guys, I found it very interesting.
All of this is cool, though I'd like to see more current transmissions than the 722.6
I talked to eurocharged about running a 722.9 and any they said good luck. It basically not worth the reverse engineering to make it work. Liget street cars installed a new valve body in to his .6 and said it was way better.

I've been running the SGA TCU in my CLK for about 9 months. It's awesome! It works with the factory ECU, talking over the CAN bus, but it will also work with the standalone Holley Dominator EFI that I'm installing. IMO it's the best transmission control option for the 722.6. FWIW, I also have the SGA "150%" valve body, a transbrake, and a 3400 stall.
There has been some recent YouTube posts on CLK 113 to 113k swaps, but the follow up is lacking. Even the shops that do the swaps seem hush hush. I'm not asking for their secrets or R&D, just some details and cost parameters would be nice. We all know "hot rods" or "modified" cars aren't cost effective but the cost of being different is justifiable to some. Built vs bought just rings true to some and showing up at a car n coffee with something built vs bought is more satisfying to many.

Running into the same issue. Euroworks Florida has one there hyping on Instagram and the quote I got from him was $13k for parts and labor. Wouldn't tell me what it costs for their labor. The engine and trans run for $3k and I'm well aware of the additional costs associated with and engine swap but ten thousand more for parts and labor above the engine and trans cost sounds outrageous. Anyone with some other numbers from previous shops completed costs would be great
...... The engine and trans run for $3k and I'm well aware of the additional costs associated with and engine swap but ten thousand more for parts and labor above the engine and trans cost sounds outrageous...
Lol.. so I see that you are not well aware of additional costs to a swap. How many hours do you think it takes to make this a turn key swap possible? 40? 60? 100? Now call around and ask some tuner shops about their hourly rate.. than maybe you will have an idea.
Please send me link for low miles m113k swap with all accessories for 3k I need it for a swap..
Original poster here, we ended up finding an SLK55 AMG in pretty good shape for under $8k, so not going to do the swap originally contemplated with this post. I'm still thinking of trying to drop a 113k engine into my R170 SLK320, but that's a whole different story...
So if going R170, did MB upgrade the ecu in 2001 to ME2.8 on this chassis? Just thinking that IF SO, it would be the way to go and use a 01-04 despite the initial cost bump to get the more consistent ecu wiring and face lift too. Either way, the conversion will cost more than base car. BUT if you get it to work, you should easily be able to reach 5lb/hp ratio and that's rarely a bad combo. Think F40 in a straight line......just do a SLK/C55 AMG brake upgrade.

My donor engine came out of a 2004 S55. The oil pan clears the crossmember and steering damper fine, so I'm just going to drop it in without messing with the pan or the oil pump. The front of the pan does protrude forward more than the W208 NA pan, and it might have interfered with the swaybar, but I have long since removed it so it's not a problem in my case.

Glad I found this. Planning on dropping in an M113k engine in my '02 Slk230. Both use me2.8 ecu would be perfect swap yes?
I'm actually in the middle of the swap now. I'm having issues getting it started, i did not swap the oil pan or pump, engine fit right in.
i swaped the ECU, EIS but I'm having an issue with the SAM module they are different so I'm stuck there. I can't swap the E55 one because they have different connections. If any one has any ideas please let me know. Thanks.

would like to know how u went with this buddy im about to tackle the same thing,or a N/A 55 swap
