floor shifter only came in 96s.
96 is also OBD2, more restrictive on computer tuning and 4 O2 sensors , all of this is easy to convert to an OBD1 system however.
94's are faster than the other 2 years too, some might argue but it's been said that they came with as much as 285 HP from factory due to a different cam grind, mine dynoed at 254 HP to rear wheels with a simple cold air intake and dynomax mufflers and a HPP hand held tune (not even a custom tune), ive seen many 95 and 96s 218-225 HP to the wheels. all cars are different however so this is not scientific proof.
94's are the rarest of the 3 years also with just over 6000 built, although that means nothing since these cars aren't worth that much anyway.
if it was me, i'd look for a 95, best of everything, you get rid of the fillers, mirrors are bigger and on the corners rather than on door and you keep it as an OBD1. a floor shifter is a $300 conversion you can do to either 94 or 95.
