2011 GLK 550 Build
Did you have to get different drive shaft?
Is this RWD?
What did you have to do with ECU and wiring harness?
Is the gauge cluster from E class as well?
Did you have to get different drive shaft? Yes, but only because of the manual transmission. An automatic V8 swap could use the stock driveshaft.
Is this RWD? Yes
What did you have to do with ECU and wiring harness? ECU and engine wiring harness are from a 2010 E550. The engine wiring harness is separate from the body harness and the only body harness modification needed is adding a 12v power wire (V6 has 1, V8 has 2)
Is the gauge cluster from E class as well? No the instrument cluster is from a facelift GLK.
Great build so far!

I got the harness, keyless go control module, and ignition in and programmed to the point of it recognizing the push to start but I need new keys before it'll actually be functional.
I didn't take any pictures sorry, it's basically just remove the seats and carpet and run the wires along with all the others.
The harness was purchased from mbparts.mbusa.com, it'll send the order to your local dealer who will likely tell you it doesn't fit your car. I just tell them to order it anyway because I know what I'm doing but ymmv. Keyless go control module and ignition were purchased from ebay, I had to program the ignition myself with an autel im508 pro. If you want keyless unlock (from the door handles) you need to purchase the door handles themselves and potentially the door control modules depending on what you already have.

I sourced the calipers from a RWD W221 with sport package in my local junkyard (Like these: W221 calipers). I had to use a 1/4 inch spacer bar to mount the calipers that I had made by SendCutSend. The rotors I got from Rockauto, they are a little less than 1" larger than stock. I had issues with the caliper rubbing on my wheels, but I have CLA 17" wheels so if you're stock you shouldn't have any problems at all.
Overall very easy, but I do think it's 100% a cosmetic modification.
The E63 will ride more like a "proper" Benz, and that powerplant makes a beautiful racket, I'm sure you'll love it.
I'm probably going to submit it to Cars and Bids or Bring a Trailer and hope for 20k.
Here's a couple pics I took of it yesterday.

Hello new on this platform I absolutely love your build man I would love to pick your brain a little Is that really all that had to be done to the ECU and body harness did you have to do any programming ECT to make it all communicate
