    No engine changes. Basically LSD, gearing and exhuast.

      What he said:

      Gearing on the Manuals stay 3.23s, but are 3.42s on autos
      You get a Limited Slip Differential
      Dual outlet muffler

      Overall no Noted HP differance, but the gearing/LSD makes them inherently faster than a non-Y87

          Read this, as was stated earlier. End of guessing.
