Actually just been looking on REALOEM now,
Seems they only came in the SMG version, meaning that the ECU does not have an option for the manual gearbox's, meaning a simple recoding wont help here, you will be able to do the mechanical swop no problem, but the ECU is going to have a heart attack, and even if you get get past the startup protection, its going to go into limp mode at any point.
Unless you can invent some PLC that can mimmic the inputs/outputs and really fool the ECU, its not impossible, but its going to be more then the 92k in terms of time, further you will then have to find a manual box with the right mounting offsets and stuff.. would be a really interesting project though still.
