I have an aftermarket 2.5 pulley on my '95 SC. You can also take a 2.5 from a '93 and get it to work. They are essentially the same pulley.
If you do do that I would also highly recommend the following items first to make sure your ride keeps running strong. Get a 180 T-stat, Tranny cooler is always good, CAI and possibly exhaust. If you put the smaller pulley on you want to make sure that the car can breathe in and exhale as good as possible to get the most out of the pulley.
...and welcome to the club!
