Thanks - helps with planning. Also related to my current A/C issue. If the engine has to come out the front I don't want to waste the time/money to fix my A/C now to then take it apart later. On the 210 you can unbolt the compressor and lift the engine straight up not have to evacuated/recharge the system. Warm weather is winding down here so not that big of a deal to wait until after the swap before fixing the A/C.

The new engine is fully prepped, engine bay is prepped, all parts on hand (hopefully - just jinxed myself). Hoping to do the install next week!

For others considering the swap - I have the upper/lower oil pans, engine support arms, and the oil pump from my C43 engine that could be swapped over to a 55 engine if it was sourced from a non-compatible chassis. This would allow you to prep the new engine while still driving the car. It would also save you from needing a second engine stand. I'll provide a list of part #s and "tasks" once I've gone thru my notes/invoices but there is a LOT to do to the donor engine before doing the swap - jobs that would take 10x as long with an engine installed.

Additionally - selling the core engine (with 200K miles) is extremely unlikely. It's just as easy to swap in a 500 or 55 and shipping will be expensive. Hence - parting the engine out may recoup some of my costs and help someone out:

• Heads - complete or separate camshafts
• flywheel/flexplate
• harmonic balancer
• valve covers (may keep and clean/paint then swap over)
• intake manifold (may keep and clean/paint then swap over)
• timing cover (I had to replace this on my 55 b/c broken P/S tabs - took over a month to find replacement!)
• may end up pulling the crank and pistons as a learning exercise.

Additionally - I have water pump, power steering pump, pulleys, all the hoses, and a bunch of other things from the original engine. I would consider these wear items and not worth putting on used - but if somebody is in a jam or has a budget build let me know.

The 200K mile engine ran GREAT but leaked oil from valve covers, front seal, rear seal, oil pan, and timing cover.

PM if interested. I'm located in Chicago IL - international shipping will be a pain to estimate so preference to USA buyers.

(a lot of the parts will fit other M112/M113s)

Thanks!

okay so i have a project proposal for you guys and that's helping me source everything i'll need to get my little small block engine to a c55 tribute machine. i have sourced some materials on here, i just need to know what kind of suspension powertrain engine (try to buy a ecu on the same engine source) and transmission, i wanted to use paddle shifters as well but will i have to remove the steering column? i appreciate your interest and any sort of tips and opinions are welcomed.

Start with a C43. Put in a M113 5.4 liter "55" engine. Done.

Rapha Nava

what if i built a c43 from a c230k?

DRBC43AMG

It can be done but it will never be a true C43. Regarding the cost it could be pretty expensive as you need plenty of mechanical parts, electronics, etc.
Look around for a good second hand 43 and be done.

Hi guys, i recently swaped in an e55 engine, at first we did not touch the ecu the car drove horeibly hickuping then going beast mode then stutters then no power it was going crazy then my mechanic decided to put an e55 map on it everything works fine in the car no fault codes all electronics working but now the car feels dead, i got to wait after i press the throttle for power to kick in then it feels sluggish on low rpm's and slowly gains power up top then somtimes it continues sluggish to higher rpm 's i was hoping for 360hp from the swap but now if i drag around 300hp cars they beat me easily :/
Could the tune have ruined the car?
What tune should i use on it?
I used to tune my cars my self from ground up boosted and N/A on standalones, megadquirt and link ecu's but never tuned a stock ecu so i decided to get a flashing kit and reading kit to see how it goes try and dabble with this one and i was wondering does anyone have the original tuning files for the c430 and the e55? The ecu is the me2.0
Or is it possible to aquire original stock maps from somewhere for free?

Which tools that mechanic used for tuning..?,,

and after tune it to 55 map, is there any codes..?!?!

-;ZAYED;-

Ang Seb

I don't know what tool it is as he didn't let me know and he black taped it so no one reads the brand but i beleive he used an adapter for it to hook it to the obd port abd it took around 30min to flash

After the 55map there was still no codes but i went to a 2nd shop and he told me my air mass unit is reading a bit odd so we changed it to a new one but nothing changed with the car performance

I ordered the kess v2 and kess k-tag and kwp and galetto with all the adapters to see wish one will work on it if all fails k-tag can read and write on a bench with probes to the chip so hopefully that part i covered still not sure where to get the original stock maps to flash cz from what i was reading the stock c43 map should adapt it self and give me reasonable power

mickey13

can it be something wrong with swap? maybe he used the wrong fuel injectors or something? my swap was flawless no need to reprogram computer. original time should be the best anyway

brad_c43

Same, my swap went flawless. Using same stock c43 tune and ecu.

Ang Seb

He installed the m113 engine original injectors the beige color ones and did the map afterwards he says the map used is for the c55 engine that come at 367hp mine is the e55 m113.986 version that comes at 355 hp i don't have any info about the map differences between the 2 but from the forums everyone says timing and fuel are the same on these engines the difference are intakes internals and accesories

cm60k

I believe (113.986) from W220 S55,,

prefer if you can put ECU/TCU from 98-00 "C43 or E55",,

C43 & E55 using the same E-Prom data & angle timing..

Something was wrong with the car before the tune. Doing the mystery tune added a variable into the mix that will just muddy the waters. The 55 runs great on the stock c43 software, just like a factory car. So something is wrong. Could be any number of things. Need proper diagnosis by a competent Mercedes mechanic.

The CLK55 engine I swapped in performs flawlessly with the C43 computer. Did you use the C43 throttle body and engine wiring harness? You need to swap those over. Are all the vacuum lines connected correctly? Something was either done incorrectly during the swap or something is wrong with the donor engine. Could be something simple like a wire, vacuum line, or sensor. No flash/tune needed.

Ang Seb

Hi guys, i have been to 4 dedicated mercedes mechanics so far all 4 agree that there is somthing wrong with the car the rpm goes up like if it was a minivan but they don't know what it is cz there are no fault codes even, today i tried a drag pull with a 260hp bimmer just to know i am mistaken or what and i barely kept up with him was humiliated to even say i have a 55 amg :/ but one thing i am noticing after i left from the mechanic today the car was cold and just as i left i was giving the car a slight pedal push and the rpm would jump like crazy temps where under 80c i reach the highway and push full throttle on 2nd gear and the car goes crazy burning tires whenever i hit the pedal i drive normal after it heated up to 90 ish i pressed the pedal and the car is like a minivan again 😭 i went back to the mechanic and told him what i experienced and he changed the coolant temp sensor but nothing changed what else can make it do that be beast mode while cold and dead while on normal temperature?

Ang Seb

Above 90c Under 80c Under 80c

brad_c43

Is that a yr 2000 c43?

Ang Seb

2001

cm60k

Good Run..,

that's interesting..!,

as i know; C43 stopped in "April/2000",,

i think you replace the cluster & steering with "W208" or "W210" one, isn't..?!?

-;ZAYED;-

Ang Seb

The car is a w208 clk430 2001 but the ecu is from a c43
Any thoughts from the videos by your experience?
I went to another mechanic yesterday he said it might be the pistons loosing pressure when it gets hot so he did a cylinder pressure test but all tested good pressure were between 11.9 to 12.6 bar still no clue whats the issue
