I think the Judge is correct. The major problem will be packaging the turbos. Room under the hood is tight and the best performace will come if the turbo is very close to the point where the ehaust exits the engine ... otherwise you loose heat (energy) needed to drive the turbo(s).
The second packaging problem involves routing the air from the turbo to the inlet. Too long a path will contribute to lag. Finally, you probably will want an intercooler (compressing air adds heat)and where the heck are you going to mount one?
If (and that a big if) you solve the above, you still need to conquer the same problems as the Vortech crowd with boost limits (6 or so psi will probably be OK, more boost = more power = more of a chance for things to go BOOM) and the inherent limits of no limited slip, somewhat marginal clutch, and weak transmision
So, at this point, the best forced induction choice is the Vortech .. one compressor to package and the engineering has already been done. Purists will argue the relative merits of a turbo over a supercharger .. that's not relevent her ... packaging is the driving factor. Want a turbo? Down-size to a Z-Tec, put in 8.5 to 1 pistons, O-ring the head, add a turbo (about 14 - 16 pounds of boost sounds good), add an intercooler, and then beef the transmission and drive train. Or you could buy another car!
