For a planned 330whp wrx.
The set up:
K&N Extream Conical filter 3" inlet w/ custom 3" pipe
Samco inlet hose
Vishnu IHI/Garrett hybrid turbo
GT-spec upipe
Ported stock headers
BPM GT Downpipe and Exhaust
MRT FMIC-emblem removed
MY TB and Manifold inlet are ported to 64mm
Type C Runners No TGV
Greddy catch can
Link ECU
Greddy gauges Boost-EGT-FP

I have MRT fuel rails
And plan to use an aeromotive FPR and a 300ZX TT pump(I love bosch pumps). I also have new STI pink injectors. My question is can they handle the task within a safe margin? Or is is a must that I sale them and go with the 650cc units? I know I can just up the pressure to get more fuel in with the STI units, but does this represent a good way to proceed, or is it a cheap compromise? Please share your opinions with me.

You should call Vishnu and see what they recommend for fueling upgrades based on their turbo. My guess is that since people with VF 30/34 turbo's can go over 90% IDC already, that the garrett would easily surpass your injectors capability.
