Default 2003 GT mod's

Hey Guys, I purchased my stang in july of 06 used of course and have had a blast with it. shortly after I purchased it I came across this site on the net and have been very impressed with the knowledge that you all have, so I figured I would pick your brains for a bit about the car: it's a 2003 GT 5spd about 60kmiles. Currently I have a: BBK 75mm TB, a Volant CAI, Maganflow weld in mufflers (still has the stock tips), a Pypes Catted X, and a Diablo Tune.

What im looking to do is get a set of patriot stage 2 heads, a set of comp cam's 272ah's, 3.73's, bbk plenum,Steeda UDP,and a stroker kit. after that i will start looking into power adders (leaning towards a single turbo setup, also looking into a vortech).

I'm not a hardcore racer or plan on being one for that matter, just looking to break some hearts at the stop light type of thing. what do you guys think of my current setup andfuture modifications? have any suggestions? any feedback good or bad is much appreciated. also as a side note, this is my daily driver as well.

forget the heads and cams and buy a mongoose kit. A vortech will definitely turn some heads and break some hearts at a light

If you're 100% sure you're going FI, pass on the pullies and thestroker kit (gives us very little on these engines) and wait on the cams. Might as well wait and get something designed for FI.

skip straight to the FI... Then build around whichever set-up you get..

NA mods and FI mods are different, so if you want some kind of boost, just get that first. Then get the proper heads, cams, etc... to compliment the FI.

Also, if you're going more than 400ish rwhp, you'll need a stronger short block. No use haveing a supercharger at 15psi if you blow your engine up.
