Michelin Pilot Sports are probably the best street tire for the car. OEM tirs in '94 was Michelin XGTZ, then in '96 moved to Michelin Pilot MXX3 when the XGTZ's were discontinued, then to Pilot Sports in ~97 or so when the Pilots were discontinued.
Short of going to autocross-level sticky tires like Kumhos or Hoosiers (which will give you no more than 5k to 10k miles), the Pilot Sports are probably your best bet for the car in terms of traction and ride quality, and even last decently well - I've been through 3 sets of Pilot Sports, and have managed to get between 20k and 35k miles per set (depending on track events and venues before I got track tires and wheels).
If you want to compare prices, note first that there are very few tires that will fit the rear wheels, and you probably want the fronts and rears to match. So, you might want to go to
www.tirerack.com and enter in the rear tire size (335/35-17 for all Gen 1 and Gen II until 1999), and you can check availability and prices from a fairly representive source.
