Your list contains a lot of stuff that just plain is not necessary to do with a basic non-cooled centrifugal blower. Sure, many of those things are cool to do, but certainly not necessary.
The Vortech V2 I bought new for $3700 was a complete kit: blower, tuner, 2nd fuel pump, bigger injectors, etc. Here are the additional costs above and beyond the initial price I paid...
$899 for installation, although I could have installed it myself in retrospect (I've since removed and reinstalled the blower once in my own garage at home).
$450 for 3 hours of dyno tuning. Vortech supplied a tuner & a 50-state legal tune, so I didn't have to do custom dyno tuning, but their supplied tune is way too conservative, plus I really wanted to maximize tuning for blower, as well as the automatic transmission and stall converter.
$140 for colder/copper spark plugs. Some kits include colder plugs. The one I bought did not. I consider this a must-have item for superchargers to prevent spark "blow-out" from the higher cylinder pressure and the colder heat range helps prevent detonation.
Sure, there are lots of other components of the car that "could" be upgraded to better reign in all that extra power, but for a daily driver that sees occasional dragstrip use, I hardly think you have to go crazy modding every other system of the car.
