ok to fit a ze into an ae82 or 92 is not a major problem, however getting a ae92 type frontcut is an easier conversion
you'll have to decide if you are going to use the e series gearbox or the c series. the c series is easier as getting the correct driveshafts is a problem (you can't use the aw11 ones)
rear gearbox mount needs to be modified & intercooler has to be relocated.
the gearbox - you need to find a fwd s/c gearbox (not a hard feat) & swap the gearshift linkage over - this all just unbolts.using the c series gearbox is simplere - but you need to swap flywheel & cluches.
