Swap C32 AMG into E320?
since there are lots of people is interested on this thread, I will make a brief DIY on different thread.
please search for W210 E320 supercharger retrofit
thank you
But then also, isn't it just easier swapping the whole engine/ECU/ EIS ? That's basically just Bolt-on !
here are the directions for supercharger installation if anyone is ever interested. these are for the Kleeman unit, however gives you idea of what you are in for with this.
Looks easier than turboing IMO
I got stuck to the idea of the C32 swap since we are talking essentially about the same block.
I found a good deal on a low mileage C32 engine, 48K and I bought it.
My car is a 4 Matic and I wanted to keep it that way, so I swapped the oil pan from the E320 engine to the C32 engine. Perfect fit.
E320 engine out C32 engine in. Exhaust manifolds were kept from the E320 due to different angle from the C32 manifolds. Easy swap. Everything bolted right in place. C32 engine came with a complete C32 engine harness and then I found a C32 ECU on eBay.
So now we have a perfect match between engine and ECU. Looking at the two ECU’s pin by pin on the body side of the ECU we noticed that it’s a 99% match on what is coming to the two ECU’s from the body. Only a couple wires were different.
I added a circulation pump for the supercharger and split the intercooler coolant circuit as most C32 owners do for better cooling of the supercharger.
With the help of a friend we copied all the info regarding key signals and immobilizer from the original ECU to the C32 ECU and everything went smoothly. Ignition recognizes the key, steering wheel unlocks, gearshift goes into gears, car starts right up, car moves and shifts normally.
Still need to do some minor tuning, deal with some vacuum lines but so far so good. Btw transmission and differential are from the E320 and if any problems occur I will deal with them as they come although I don’t plan to go racing.
Attached is a video of the first start up and a few more from the engine in the car…
More updates to come after everything is in place, I just wanted to share this as soon as we got it going.

I am sure much more goes into the turn the key part as you outlined
