chris how about the smg tranny off the e60 or newer tranny's?

the E60 M5 uses the E39 M5 manual tranny iirc, but let me see what i can dig in

The Alpina Z8 came in automatic tranny but didnt use the E39 M5 motor...

here's their take:
An Alpina version of the Z8 with an automatic transmission instead of the six-speed manual seemed the ideal "door opener" for the U.S. Such a car was already being developed. Alpina had wanted to install its version of the BMW V-12, but it wouldn't fit; the engine's oil sump needed the same space as the rack-and-pinion steering system. The high-revving M5 motor was not suitable for an automatic transmission. But that 4.8-liter V-8 from the 5-series Alpina B10 V-8 S, with its attendant Alpina-specified five-speed ZF automatic, would fit right in.

Fitting an S62 inside the E46 is doable, but you might have to leave the SMG tranny out of it. You might want to take the S62 and it's transmission to make it work, I've seen it done before. That's not necessarily the biggest issue though. The steering rack on the E46 would have to go THROUGH the spaghetti like headers for the driver side, which can be an issue. I don't know if that is a custom header job, or if maybe supersprint headers will do it etc...

It's a tough job, but I've seen it done before. If you pay a guy the right amount, I'm sure he'll fit it in there. I say do it, Hartge did it and made it a production car

what i wanted to do in the first place was a e60 motor and tranny....but thats big time bucks...the main goal is to have a smg tranny in it but if that can't happen then i'd have to scratch the project and maybe drop in a 540 motor...
