I have started piecing together my own turbo kit and have a few questions.

My questions:
What size injectors should I run?
When tuned about how much power will I be putting to the ground?
Which Wideband O2 should I get, and where?

Here is what I have now:

Topspeed Header
TurboXS Up-Pipe
HKS Down-Pipe
Tanabe Super Racing Medallion Exhaust
Lightened Flywheel
ACT 6-puck clutch w/ HD pressure plate
TurboXS MBC
APS Cold Air Intake
C&R Radiator

My "kit" is going to consist of:

STi VF39 turbo
Perrin Fuel Rails
AVO Silicone Turbo Inlet
JDM STi Intake Manifold w/ tumblers
APS D/R500 Front Mount
Walbro 255 fuel pump
Larger Injectors
Wideband O2
S-AFC 2

I will be adding some other misc stuff like pullies and the like. For now I just need my questions at the top answered.

If some one could help me I would greatly appreciate it.

Nick

Yea, I forgot, it is a 2002 WRX. If you don't remember, you posted in my other thread I put on here.
