I don't KNOW how close the E46 and E90 are in their CANBus system, but I would THINK they are similar enough that these guys would be able to help you sort something out.
I have a basic iron block LM7 (what I'm using as my mockup right now) that I plan to keep and rebuild. For my wife's 325i, the extra 100lbs of iron block doesn't bother me and for $1000 parts and labor I can have a brand new motor that will take butt loads of PSI if I want it. I think a 750rwhp 325i (that still gets 35-40mpg) would be a pretty nice "wife's car"....  |
Thanks. I need to read more on the wiring and electronics for sure. Not sure if you have seen this thread on LS1tech, but a guy with an E46 used both ecu's in tandem and just made the BMW dme think the car was running.

You should definitely start a thread on ls1tech for your build in the hybrid section. I have seen Z3s before with LS engines but never a z4.
