What if I go with the supercharge? What needs to be done?

I just dont want to make the mistake of buying all this bolt ons & end up getting rid of it when I go with the S/C or turbo.
Just debating which one to go for rite now between the two
I hear the S/C is more reliable than the Turbo.

Whats the most you can get ( HP & Torque ) from the SC with a stock motor?

Help me out yall, cuz im itch'n to do up my ride asap. Just want to do it right the 1st time.
