In the Future....

Well everybody...I know it's gonna be a long ways off cause of college and car payments and whatnot...but I really wanna mod my lude. I was thinking at some point going either boosted or blown, but I don't know which route would be better...I autocross and I was thinking about doing a supercharger since they help more with the low end power band.
Also, which brands would be best, and would there be a considerable amount of internal mods that I'd have to do for the increased power?
Thanks for your help
