What you think of this upgrade for a MY05 WRX PPP
 

Ive currently got a 2005 WRX PPP and looking at eeking more power out of it, let me know what you think of this setup, any pro's and cons and anything that you'd change...

Im aiming for over 300bhp range...

Walbro Fuel Pump
STI Pink 550 Injectors
NGK PFR 7B Sparks
Andy Forrest TD04 Hybrid Turbo
Decat Up Pipe
Sports Cat Downpipe
Blitz Nur Spec Exhaust

And obviously a Remap.

The car already has...

Uprated Air Filter
Prodrive Intercooler Y Pipe
and various other mods like oil catch tanks and throttle body coolant bypass etc

Would I need to up the Intercooler to an STI one or would the WRX one do the job ok?

i think you will need to up the cooling so an STi tmic would be recomended, all the other mods seem fine and should see you 300+bhp. you could also consider the VF34/35 turbos, both very good

I just got 300/290 from 05 wrx:
samco intercooler pipes
KN filter
Vf35 turbo
up and down decats
walboro pump
Mocom remap (i can recommend)
