Find a 94/95 T5 tranny if you can. They are the correct length and will be the easiest for the swap.
You'll need:
Trans/bell/block plate
trans mount
set of pedals
quadrant (if not on pedals), cable, fw adjuster (all best bought in a kit)
shifter, boot, knob
dust cover for shifter
dust cover for bell housing shift fork
clutch kit (depending on trans you get)
flywheel (86-95 will all work)
On the electronics, not sure how sensitive the SN ECUs are. Will you need a 5sp computer? Not sure. The tranny harness has a neutral safety switch, you must bypass this and add one on the clutch pedal. The harnesses are the same IIRC, your car will have a jumper on the clutch side (since there is no clutch pedal), that jumper needs to be put on the NSS harness. Or there are other ways of bypassing it electronically.
I just saw a 95 T5 with bell/clutch/shifter on craigs for $700 localy, so finding something like that would be ideal.
