Toyota GT 86 - Supercharge Or Turbo Kit

I'm on the waiting list atm for my GT 86 to arrive to pass the time I'm looking at the first upgrade and i really gotta pick A Supercharger or a turbo anyone got some input? I'm pretty new to the after market scene, I was hoping TRD would deal and give me a charge from the factory but no dice =( in fact in the Toyota Dealership my options were seriously limited.
