So guys, if a 55K works in a CLK, I imagine that it is possible in a w202. No word if all the electronics got to be working together. An extra search perhaps?

Money-one was able to do it in his car on the stock ECU, I'm planning on doing it to mine when I can find a good 55k engine nearby.

Edit: Heres a link to his thread: https://mbworld.org/forums/c36-amg-c...you-can-t.html

Pretty sure he abandoned the 55k..

Check post #251
"During that 2 month down time I decided to throw in the towl on this swap and decided on a second option.
After discussing this with my tunner we will be dropping in a 2jz engine matted up to a V160 getrag."

Still shows that it can be done. By that point he had it working properly and was trying for more power.

Pity he didnt document the details which solved the electronics... Or I havn't seen it

m00nsh0t

My understanding is that he just modified the harness to plug into the new engine and used the stock ECU. Not sure how he got the bypass working though.

IMO; this set-up causes much Headache & lose time with lose much much $$$$$$..!

i know many guys who ends-up with very bad & risky results,

you can unleash the power on this great C43, in better way;

you can put Kleemann cams & headers with full Exhaust system, and good custom air intake, then remap the ECU (as optional),,

i can assure that, you will love the Results,

if you need more power, you can add any S/C easily, without fear, cause you already got all performance parts above..

ZAYED,,

He never solved the electronics, that's the whole point here I think. He managed to get it in and nearly resolved the all the mechanical issues, but he states that the W211 engine has a known issue of failure (crank came loose) and decided to scrap the project to deal with a more reliable engine. So I don't think there has been a successful W202 55K swap. Also he does allude that it will cost him another $3,000.00 to get the electronics working and says he can use independent controls for lower costs.

So I am guessing you will need a W211 ecu, custom wiring and programming done to get it to play nice in the W202.

So the W211 55K put out 469 hp 520 lb torque. I see them on ebay for around $2500-3000, but you'll probably want to do a rehaul on both the engine and the supercharger since it's already out and will have more than 100k miles. Plus there is the cooling system, all the little things that go with putting in a charger since it isn't plug and play (this is going to cost the same as installing an aftermarket charger as these parts aren't going to come with the 55K).

I think you are better off with doing a s/c build on an 55 n/a - dollar-wise and maybe headache wise too, not to mention you can get greater gains on a custom build. If you want plug and play then it's simple just put in a 55n/a. Even with the cost of a bare minimum rebuild (seals and gaskets - and taking a look for worn parts) you are looking at dollar for dollar a better value.


Edit: Also wanted to say there is a reason MB has the s/c in the W211 on the lowest possible setting and it isn't done so the engine can have extra power!

mickey13

He stated this:

The bypass is recirculating back into the lower part of the S/c inlet.

Another poster had given him this advice:

the bypass valve needs to be routed back to the pipeline

And because the W202 ecu cannot control the clutch plate so the s/c would be on all the time, he also said:

you are going to need two bypass valves. One per surge tank.

mickey13

Zayed correct as usual or should I say 100% of the time? LOL

If you SC a 55na, what do you do with the compression ration? 11:1 or something like that as OE together with a SC that's sounds like a potential and expensive BANG

mickey13

I can scour around to find an answer, but in all honesty I don't know. Something I would leave to the experts to decide. If I sleeve, it means I will get forged rods and pistons to match the sleeve and I am guessing they will tell me how much compression they are rated for. More expensive usually better quality. I believe the 55k supercharger is on the lowest setting because the internals cannot handle it. Sometimes in the engine they lower the compression to increase the boost. And I know they play with the heads to adjust more if needed.

sick430

You can run an SC with 11:1, you just run lower boost. Also a few years back one of the CLK amg guys put the 55k sc on an NA 55 block. I know a few that have done this.

this dude put a 55K in his c43

Speedriven1

I've been talking to a local guy about doing this- it's definitely possible.

DRBC43AMG

Same guy racing a E63. Guess who won....? Grandma!

DRBC43AMG

So it looks like it can be done and it works too

We definitely need further details, as this is probably THE ultimate conversion for the c43

eFifty5AMG

How do you do it?!

mickey13

I don't want to be the guy who rains on parades, but he also has a video of a w124 with a 55k.

I'm just guessing they use external controls to get it running right. Please though, if you know let me know and maybe I will reconsider my 55 n/a build.

PJmak

Its all doable with enough money and knowledge
