Turbo exchange list

Alright I was originally going to go with an AGP turbo setup. Turns out, my speed shop can't get any AGP products and importing them from the US would be rather costly with customs and all.

So here was my origianl set up:
AGP Turbo Kit
Full Race turbo upgrade
* Race manifold T3/T4
* 50 trim T3/T4
* .63 AR Housing
* 700+hp race intercooler kit
* HKS SSQV BOV
* 38mm Evolution wastegate 3" intake

What would you guys recommend to replace each one of these items? Looking to hit the 450-500hp range.

My mod list (minus the AGP KIT):

ACT XACT Streetlite flywheel
ACT Maxx Xtreme Clutch Kit
APEXi Super AFC II
DC SPORT Carbon steel strut tower bars (front)
DC SPORT Carbon steel strut tower bars (rear)
GREDDY EVO2 exhaust
