    Starting my swap...

    Well, my head gasket and my transmission took a crap in my 528... With almost 200k on the clock, not a shocker.
    So I'll be swapping in an ls3 from here (already purchased): http://www.crateenginedepot.com/stor...P2218C509.aspx

    This transmission: http://www.monstertrans.com/store/pr...tml?fullSite=1

    And an M5 rear diff and one piece custom driveshaft.
    I'll be making the exhaust and mounts myself.

    But my biggest problem is getting all the new stuff to work with the cluster and all that. I got a stand alone ECU and TCU but I'll be needing help with wiring and programming of modules.
    If anyone could help when I get there or put up some links with good info I'd appreciate it... I'm sure I'll have lots of questions along the way.

    I'll be starting the teardown soon...

    Damn, that should be a great set up. What stand alone are you running for the engine and trans?

    Just a regular GM performance parts ECU: http://www.crateenginedepot.com/stor...7-P2221C0.aspx

    Talk about awesome potential. There are several E36 LS swaps in Oregon, I'm sure they'll chime in. Looking forward to seeing this develop, take lots of pics!

    Nice!! takes lots of pictures!! one thing though, that engine is pretty pricey. you could've built up a motor for less but your setup is gonna be killer

    Actually, for a used ls3 with 30k miles was about $1000 less... So I decided on a new one.

    I am sure that engine is in excellent condition

    OP - the whole swap shouldn't cost more than $1k if you know what you are doing.

    Engine and all?! Engine and auto transmissions are things I don't like to buy used, especially site un seen and from a junk yard... to many variables that cause serious damage to internals.

    I'll try and document as much as I can...

    My budget is about 15-16k engine, tans, misc...

    I'm gonna try and part out my engine to recover a few pennies..

    My budget is pretty high, I know, but I don't plan on ever getting rid of this car, and I'm going to have it insured for more than what I have into it.

    E39 + LSx = match made in heaven. However I have heard Turbo M50 is better.
    Good luck with the swap

    Thanks schitzo, I've read yours and rao's treads about 10 times each.... I'm sure I'll still have questions tho.

    If you check my thread, I pretty much detail how to recode the cluster and what you need to do it.

    I also go into how I went about tying the GM harness into what little is needed to/from the bmw to make it run.

    We need an e39 swap club!!!

    Yah, your thread has been the most helpful as far as wiring... I've got a few ideas on how to do it.

    A swap club would be sick... I think bimmerfest would be the best time and place to meet up... But it's a long drive for everyone.

    So... The ls3 can communicate over a CAN bus, can this be adapted to the existing BMW can bus? Instead of converting both the PCM and cluster to use analog signals, could I make them communicate over the CAN bus?

    Unfortunately not.
    Even though both GM and BMW use Can-Bus for communication between modules, the CAN-IDs used for the various messages are different meaning a BMW module cannot understand a message sent over CAN-BUS from a GM module.
    The key to figuring out CAN-BUS systems will be to crack or acquire .DBC files used by the various auto makers. Such a file would contain all the information describing the respective CAN-BUS network, message IDs, their priorities etc.

    Figured it was a long shot, thanks tho.

    Another thing, could I make my own cluster of whatever guages and not have issues elsewhere in the car? (i.e. lcm)
    Or should I just stick with the stock cluster and convert everything to analog?

    Stick with your cluster. The only thing that needs to be converted to analog is your tach and coolant temp. It will not cause issues elsewhere.

    Thanks again for your help. I know I'm a ways away from dealing with this, but I want to be as prepared as possible.

    If you're anal like me, switch over your MPG gauge to analog also

    I maxed it out in the cluster function at 1250 and it's still about 8% or so off. I will fix that someday too.

    ^^^Did you wire it to an injector signal wire? I didnt feel comfortable doing that.
