Looking to do a Conversion of an E46 M3 s54 engine into my track day car (E36) and want to go SMG II. My father has issues sometimes with changing gear and would help him out. So want to know whats invloved in the paddle shift part, is it electric, and wired that way through the ECU? is its something a stand alone ECU could control? Spoke with Reyland regarding doing the work and asked to do a little more research into it so that the job can be cheaper and easier.

Seems the s54 fits in on the normal mounts but want to sort out the gearbox first before i buy the engine. Other choice was a LS1 engine in it for a bit of V8 grunt!
