I'm no expert on supercharged Z's and I only know what I have seen, I have known two people with procharged VQ's, both got rid of it because it doesn't deliver, the M3 should have no problem with one and most certainly a stock Z. Vortech and HKS make the best superchargers for the VQ but most often guys will switch to turbo when they want big horsepower.

Curb weight on a Z is around 3300lb.. maybe 3200 on the track edition but add a supercharger and other mods and its easily heavier than an M3.
