Heh yea, I understand the " F$@# IT! I WANT MY POWER NOW!" That's why I skipped all the silly bolt-ons and jumped right into a turbo myself.
I'm just on the cusp of realizing all that work too, just has to get out of the shop!
If you really want a turbo, a good single kit is pretty easy to find for a decent price, probably alot more reasonable than the price of a twin you were looking at. (since that's just the nature of a TT system, y'know double the product, double the cost)
If you're just looking for some "Stomp on the pedal and fly" power, you can get that with a simple Vortech or Paxton system for a really nice price.

 

I was looking at a 62 mm turbonetics turbo i can get instaled and tuned for 5.5k. If i got a supercharger it would have to be a twin screw. I guess ill just have to look if i can find another good used deal
