Dude if you could pull this off it would be awesome. I'm a Bentley tech and I too deal with CAN systems all day long and although I'm not a Rolls Royce tech I see what the Rolls techs deal with (Rolls is owned by BMW and they both use the GT1 system while Bentley's are more like the Audi system though not as complicated) and let me tell you its hard enough just dealing with the factory systems. You start playing around with it trying to make different manufacturer systems talk to each other especially Delphi and Bosh boy oh boy you better have thorough understanding of both systems to do that. I don't know any technician who has. The instructors at the training facilities would know but to get two different instructors from two different manufacturors to agree to anything would be a real feat. Good luck!

Here's a 6-speed LS1 in an E46 wagon: http://www.swapcartech.com/forum/showthread.php?t=881
It's being built/was built(?) by Idaho Speed Center, try contacting them for info about the wiring difficulties. They might also be able to sell you a complete conversion kit.

I would this a M5 motor would be easyer considering it used all OEM Bmw senors...Im sure they use the same sensors etc in there other cars...
Ive seen alot of Z Bimmers with M5 motors.........
The inline 6 is a really great motor, the Rotory is a plagued problem child that could make power but its a pain in the ***....
Why not put a Blower or a good nicly matched turbo setup on your car?

Because the LS blocks are
more compact (weight to center of car)
lighter
more fuel efficent
more hp
more torque
more reliable
more modable
sound better
less likely to overheat at the track than FI stock block

s54's get mid 20's lsx get mid 20's mpg
with a turbo you could have more torque and hp
not going to be reliable as what came in the car.
the cooling system on the stock m3s are overkill.

I've never gotten more than 18mpg avg and I drive a lot of highway miles-- driven the car 50k miles in 1.5 years

Man your gonna have to abandon all the stock electrics in your car and treat it like a kit car and wire in your own **** like aftermarket traction control and a stand alone type ABS from an old Volvo or something. Just use the Speartech harness for the engine and then rewire the whole car with a painless chassis kit etc. cuz there is no way your gonna get the Bosch and Delphi electronics to talk to each other.

I could be wrong but I believe the BMW uses a Bosch 5.7 system.
using the GM ABS/ASR system in the BMW might not work. The The # of teeth on your BMW might be different from those on the corvette (assuming you used the corvette system). Such a difference would send a signal out of range to the ABS comp throwing it off. The two cars also have different weight biases which would matter.
If you are serous about doing this swap, I say go for it. Physically its doable its the electronics that will hold you back. I think the older BMWs (90-94) might have ABS/ASR systems that will work with the LS1 comp. retrofiting those older BMW systems, might be one way to go.
All the best
agree

Wow. You need alot more than a fat wallet to get where you want to go. Besides the fact that I'm also a master tech for BMW, cam72aro is correct. Almost all the data that goes to the instrument cluster is sent over the CAN bus, with only a few backups being hard wired. Also, a traction control system from another car has absolutely no chance of working due to the different calibrations of the vehicles (wheelbase, track, steering ratio, etc). It is a pipe dream to think anything would function normally once you rip out part of the system and replace it with something non-BMW. Cheers.
