What is the difference between the 92-93s and 94-95s. What did they do to the */C in 94 to give it more hp and tourque? Could I hook up a 94-95 */C to a 93' and get 225hp and 275ftlb.?

The throttle body is larger, the rotors are teflon coated. The SC case was revised to accomodate the larger TB, and the rear corner base was made thinner to use the same length bolt as the rest holding the bloser down. I have my suspicions that the rotors are also larger than 92/93. The ribs on the 92/93 are taller, so I think the rotor housing walls were pushed out a little to make room for the larger rotors.

To swap, you'll need the SC, TB, and a MAF recalibrator like the one from ZZP. And a new (shorter) bolt or several washers for the driver'* side rear SC to lower manifold bolt. And the associated gaskets.
