    M Powered: A Motor Swap Story

    Project 325why?

    Updated 7/29/07-
    This is my motor swap story.
    The project:
    2003 M3 S54 motor, 19k miles, 6speed transmission
    Vehicle:
    1993 325is.

    Chapter I: The Devil Went Down to Georgia.
    It was an early call this morning. 5:00am. Got up, got showered, got dressed, and got in the truck. We were off!
    Our tow vehicle was a new Ford expedition.


    We were prepped to get there as fast as possible with the V1

    It was only a few hours before we hit the border


    But once we hit georgia, things got funny and ricey.
    We spotted this speed machince-


    and this 'beaut. God it was fugly.


    its only got better when I saw this:
    Black cargo on board!


    I also spotted this sweet 190e, Im guessing an EVO clone of sorts.. it sounded awesome!




    I had to rep the motorcyclers out today-


    and lastly, a clean GTO right before we got there-


    and finally, after 4 hours of driving, I got the prize!
    no, its not rust, just dirt from a dusty shop.


    The Wiring harness:


    the cluster:


    And after the long trip home, we had to hit the bikes before it got dark:


    Look for Chapter Two soon!


    Chapter 2- Ripping the Guts from the Beast
    Here we are at part 2. This time, it wasnt as clean
    Now the M50 is out!
    Start time: 6:00pm
    End time: 9:00pm

    Step One: get prepared. We layed out the tools, and cleaned up our work area.


    Step Two:
    disconnect the wiring harness!


    Step Three:
    Remove cooling system:


    Then we put it up on stands, and got dirty


    Dropped the exhaust, driveshaft, transmission crossmembers, and motor mounts, and your pretty close to this:


    Finally, wiggle the motor free!




    The easy part is done.
    Not bad for 3 hours, give or take a half hour, eh?
    Im gonna clean it up and hope to get the S54 mounted soon.

    Intermission-
    So now I have to wait for stuff to come in and such. Mainly the motor mounts.. its awfully hard to mount a motor without them.

    Well, they got here today..


    and I also have these things sitting around, waiting to go on....



    (the fogs have yellow lamin-x on them, which is coming off. I am not a fan of french fogs.)

    Also, while the car is up, I plan on lowering it a little more.


    I cant post any more images in this post, so further chapters will be linked to other posts in the thread.

    Chapter 5- Preparation

    Chapter 6- Test..1..2.. Test..1..2..


    Chapter 7- "Thats just not going to fit."

    so your going to try to use the stock s54 wiring harness and adapt it to the e36?

    i know thats how another member did this swap but he wouldnt go about how it was accomplished.

    Apparently it is much easier to use the wiring harness and ECU from an S54 M Coupe/Roadster since it is a closer sibling of the E36.

    I want another E36
    hmm, this sounds really good. post detailed info about the adaptation of the wiring harness, and any probs you ran into swapping the motor. this could be a potential mod for me.
