The 1989 Ford Mustang was rated at 225 HP and 300 ft/lbs of torque from the factory. You'd see around 195 HP at the rear wheels probably in stock trim. That was the only engine option. You either had a 4-cylinder or the 5.0L engine.

The only option I know of off hand was that you could order a Mustang through those rears with a 3.08 rear-end gearset versus the standard 2.73 gearset. Either AOD or Borg Warner T5 manual.
Hope that helps...
