I don't know where you got your information, but you are dead wrong.

The S/C engine does not have the same compression as the N/A engine.

A S/C can be added, but a lot of stuff has to be changed over. A secondary air/fuel ratio computer, boost controller and an adjustable fuel pressure regulator are just the start. The different coolant, pressure and vacuum tubes all have to changed as well. A different bracket for the A/C, and a different crank pulley also have to found and swapped. Throttle body brackets, lower intake manifold, all the braces and hoses as well as wiring that would accomodate the differences. Including different plug wires! How far do you want to go?

If you found a totalled one, then pulled everything off, then it'd be feasable. But otherwise, it'd be so cost prohibitive.

I happen to have a SuperCharger for sale, if'n anyone has the gumption to go for it.
