Alright after being ripped off the first time and getting everything but the head unit itself...I finally found a p1sc with less than a 1000 miles on it for 1500. Now I know I need the bracket and a pulley, but I don't know what size pulley I should run. I will be running a custom power pipe and a 3 row intercooler. My car is an auto and I'm looking to run 10 lbs of boost and make around 375rwhp.

 

a 3.6 pulley should get you around 10psi.
