hi i own a 2002 w68 y87 firebird and my question is what was changed in the engine as opposed to just the regular base firebird?

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

I thought the steering ratio changed too.

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