Personally, I don't think I'd get a "package." I would buy the items seperately that I like. You would want a PCM, plugs, thermostat, intake, and all that normal stuff obviously. But as far as rockers and headers I'm not sure I would go that route.
I'd start off with an intake (make your own for like $80 or less), pcm (around $80-100), plugs (~$15), tstat (~$10), and pulley (~$50), and go from there. You're talking about $250 for all that. From there get a cam, install kit, springs, retainers, timing chain, etc..., and that should be another $600. Get some used SLP'* or TOG'* off clubgp for like $450-500 or so if you can find them, or maybe spring for some pacesetters (not sure if they'll fit on a bonnie) for $400. If that costs you $500, you're still only at $1350 total. There you have a better setup (IMO) then the intense "package". With the money you have left you could throw and SS I/C on it as well. For $2k you could have all that on the car and there should be no reason why you wouldn't be performing significantly better than you would with the Intense kit. The biggest thing is just if you can install all this yourself. If you can't install it yourself, then this would probably change my plans.
I'm not saying there is anything wrong with the kit, its a good kit with stuff that is going to work together. However, I think if you do your homework you'll find that you can probably make your car go faster for cheaper. Being a poor college student, and wanting to make my car go fast at the same time, getting the most out of my car for the money is a big concern so I look around a lot to see what seems like the best deal.
Using the classifieds on clubgp has seemed to pay off pretty well for me and you may want to try that as well.
Hope that helps.
