???? Charger Question ????

[IslandBlueStang]

I have a 2002 Stang and I was wondering what I have to do exactly to my engine to add a 6, 7 or 8 psi supercharger. I talked to a couple techiees, and they told me that a stock 02 engine is ok for only a 6,7, or 8 psi charger. I want some more power with out huge $$$. They told me that you would not have to touch the bottom end.

If anyone has done this to their engine let me know what you went through, it would be greatly appreciated.

Thanks,
