Default Can a N54 BMW Engine Be Swapped Into A SLK? - 08-19-2020, 02:02 AM

I want to swap a BMW N54 engine into a 2004 SLK/CLK. I have a good amount of experience with the N54 engine. I'm a little worried about the electrical part of the future project. What things will I need to mod to get the SLK running right?

I know I need the following

1.Engine assembly and Transmission
2. Bigger Brakes
3.Engine computer or ECM
4. All the other engine components

What parts will I have to transfer from the donor 335? Is there stuff in the foot well module I have to wire up?

Is there a wiring diagram online for the SLK? Would a N54 swap be similar to a LS swap?

Thanks for any help.
