240Z 5-spd into 240SX/S13 w/AT

[Geezer]

I have a '91 240SX/S13 w/AT. I want to install a Euro Z 5-spd (FS5C71B) transmission (basically, this is just a 280Z 5-spd w/CR gears & Porsche synchros). Anyway, has anyone installed a 280Z 5-spd into a 240SX w/AT? I know about the bell/gear housing, flywheel/clutch & clutch pedal (including m/cyl, slave cyl & lines). Questions primarily deal w/shifter, driveshaft & wiring mods. Also, does the ECU have to be changed to a M/T unit? Are there any sites out there that already have this info on file? Thanks for your help.
