No worries dude, I'm still learning too, if you guys saw my ride before my WRX you'd laugh, and understand why I know so little.
Anyway, just a general rule of thumb with turbos, I've learned that aside from an Uppipe (pre-turbo cat), most of the horsepower and torque is made after the turbo. Exhaust, Downpipes, Headers, etc, Or with engine management systems. I haven't seen gains from intakes, or filters that really make it worth doing. I've heard over and over, to spend your money on these parts, and leave the intakes to the N/A cars.
good luck
