E55K Engine in a W208 CLK?
#26
I've been trying to figure out why the swap wouldnt work but cant figure it out. Arent both the engine and trans externally the same as a CLK55? SO it should bolt up. If I take the ECU/TCU out of a E55 then why wouldnt it work? I am really confused Can someone please clarify this for me? Thanks
I wont turbo the 430 motor. If anything I would sell the kleemann stuff off the 55 and turbo that. Might as well go all out.

The more you can get your hands on the better.You might find it easier to swap an entire harness etc. In my earlier days I have swapped quite a few motors and trans in cars,having more parts is always better.

The engine mounts I can tell you are entirely different.It would still be an interesting project if you can get someone to make it wrk. Just make sure your pockets r deep!

..........I don't think anyone has said it won't work. The mechanical part of getting the engine and hoses and screws to fit is easy. Tuning it will be difficult. The guy that put the engine in will blame the guy that modified the ECU and the guy that modified the ECU will blame the guy that washed your car. Meanwhile you the owner is stuck with a car that can't be driven. I've ben there. Best if one person that claims they can do it does the mechanical work and the tunning as well as the car wash. And you pay them after the project is completed and the car is driveable. Just buying an engine and having it dropped into your CLK is no big feat IMHO. It is what comes afterwards that is difficult. So my view is that there are always so many arm chair experts on this topic. Everyone knows a cousin who has a lambo engine in their kia or 10 turbos in their Mercedes, yet no one has produced a single Mercedes with a stand alone engine management system that has actually been physically installed and working. I don't mean one they THINK will work. I mean one that has been installed and working already. Let one of them step up and agree to do it. Agree on a fixed price and the person only gets paid after project completion and appropriate test drive. It can be done, just bewars of bogus claims from folks that will leave you stranded.

In terms of the turbo on the 55. I COMPLETELY understand the issue with tuning. I've been searching forever and almost pulled the trigger several times. Just as you stated, they claim alot but have yet to actually do it. Dont know if I want to be the guinea pig. I would not even attempt that myself but I know I can get all the hardware fabricated. The rewards sometimes make me think its worth the risk. 5.4L V8 with top mount GT35R's 650+whp on pump gas EASY with not much lag at all!
I know you have personally been through alot in terms of pushing the boundaries. I applaud you for that. If we had mor epeople like that it would be like the BMW/Audi community and we would all be better off. I'm trying to do my part.

Now if you want to use aftermarket ECU, like AEM or others - you are in the world of hurt. You will need to competely rewire the car and reverse engineer communication protocols that keep everything happy. Possible, but the very labor intensive and thus expensive.

Like Vadim said, if you go aftermarket engine management, you will run into network issues with traction systems and the instrument cluster, even the climate control could have issues, since the factory system measures torque load of the a/c compressor on the engine. If you go with an 03 e55 ecu and trans ecu, the ignition switch still has a vin number in it that won't match with the engine and trans modules. The car won't even start. The donor car and your car use different traction systems aren't even the same, they use different data transfer rates. The AMG supercharger is clutch driven, which is controlled by the rear SAM, in the trunk. Your car doesn't have one, let alone anything that would control it. As for the trans, the AMG kompressor one is longer, so you would have to fabricate a new rear transmission mount and crossmember, and also shorten the driveshaft. The AMG exhaust manifolds will not bolt up to your factory catalysts, so you would need a custom, high flow exhaust also. Not to mention cooling system planning, and intercooler placement, you will have a lot of work to do. I would use the 03 e55 motor, minus the supercharger, and use a Kleeman charger that is capable of the same boost, run by the MY 2000 engine control unit. Good Luck, let us know what happens.

Kleeman could probably make you a pulley that would give you more boost, and you could use the Kompressor long block, which is stronger, and uses lower compression pistons. Put the revised Kleeman supercharger on top, and shred tires! Ok, run a larger fuel line, and maybe the Kompressor injectors, and you will be on your way. At least, that's the basics of it.

I personally don't think the mechanical work on the conversion is bad at all. As to the electronics, it would be a real PITA but if it were me, I would pull the entire wiring harness/buss system with all modules out of the E55 and put them in the CLK. You would have to carefully document the removal of everything to a proper reinstallation but it could be done. This could require extra fabrication work for things like the ignition barrel, instrument cluster, etc but in can probably be done. The only big issue that I see is the lack of air suspension and SBC braking in the CLK but everything else may well run without this stuff connected or you could build "hacks" to fool these systems.
It can all be done and done cost effectively if you can provide the labor for free. Just keep in mind that there will be lots of it. In the end, it may be a fun project if you have the time and would be a monster.
Oh, and don't forget the CLK DTM bodywork!

Sunil is already doing it. The key is to be able to get DME and other controllers to think of CLK as an E-class. If you can do that, than it is fairly affordable and achievable project.

Lol Jason! I just found a wrecked E55 and could get engine/trans/ecu/tcu/instrument cluster for $10k and I thought it would be worth a shot. Turns out its much more work than I expected. 996TT would cost quite a bit more. And honestly I think I'd rather have a C6 Z06, the prices are dropping like crazy right now. But I am not looking for a new car right now. Will call Vadim and see what they have to offer for me
