Welcome mate
The Vortech is the kit i'd go with for supercharging, so much info on it on american sites and how to make your car as safe as possible with it on. Seems like the best all round IMO.
For turbo's I'd go for the Power Enterprise, which Envy have fitted to their car. It retains the original character of the car whilst giving ridiculous performance Not as tuneable as others but if you want 380bhp then it's perfect. Envy can source and fit for less than 6k.
Have you considered Nitrous? Just another option if you don't always need boost. . .
