Noob intro

Hello everybody I'm an new mustang owner I have a 2000 rpush with the two valve engine and I'm looking for help and advice on how to get crazy horsepower . My goal is to have a built 2 valve motor and eventually supercharge it with lots of boost. If anybody has any suggestions on how to do this or has done it themselves or maybe even has a built engine for sale please let me know Potsiewebber@verizon.net thanks

I'm having some body work on the car done so I will post pics when I get it back. Also it is a 6 speed tranny not sure which one I would guess 03/04 cobra. The highest horses I've had in a car to date is 400 wheel not nearly enough so I am looking for between 500 and 600 whp. I guess boosting will be well over 10 psi. I don't have a fixed budget but I would like to get a used supercharger setup to save on costs. Will a 03/04 cobra stock s/c work on this motor? Also it would be nice to get an already built 2v that may save on cost as well. What is a typical cost of a forged engine build?
