Hey I was feeling pretty power hungry yesterday surfing the web

, and I found these squire turbo systems (STS) The one (I believe it's twin turbo) built specifically for the 05-09 v6 mustang is 4,995 with tuning, and the universal twin turbo kit starts at $2,745 with options that include: blow off valve kit - $300; PCV Kit-$150; Raw pipe, clamps, and silicone kit for $550; and twin snorkle kit for $100-120. I don't exactly know what all of that is but I would probably get it lol.
If I would happen to save up for this, and purchase this, do you think I should purchase the universal for 1,000 dollars cheaper, or get the one that is under the v6 mustang drop-down?
Also, the maximum boost that they offer for the v6 is 9 psi, which I think is good. If I happened to get that system, would I have to do anything else with my engine besides tune? Like I wouldn't have to spend thousands making the engine stronger or anything....would I?
http://www.ststurbo.com/universal_turbo_systems here's the link, if it works correctly it should be on the universal twin turbo page (if you scroll down) and on the left you should be able to click on one or two links to get you to the v6 mustang turbo system.
