So to elaborate on my title "what do?" I have a few questions that I need answering. I've searched Google for a bit now and seem to be searching in circles, finding contradicting answers and even possibly ignorant ones as well. So that brings me to here.
So to be blunt, I am planning on upgrading the turbo on my 2004 WRX.
My current mods are -
Stage 2 Cobb OTS Map (AP v3)
100% Catless, 3 inch Turboback
Catless Up pipe
Cobb Short Ram SF Intake
Walbro 255Lh Fuel Pump
Turbo inlet Hose
Now I already know that I'll need bigger injectors and a better intercooler. My questions are more geared to mods related to the turbo itself.
I am looking at an EWG (external waste gate) and an EBCS (Electronic Boost Control Solenoid).
I'm leaning towards the 18g turbo be am still looking at some of the cheaper VF turbos. Haven't decided yet.
So besides a tune, what will I need for the EWG and EBCS to work for my set up? Obviously a new up pipe with a cut out for the EWG.
Would an EBCS be beneficial for a WRX with an upgraded turbo?
Here are all the parts I'm considering:

And then a better intercooler... Still haven't decided which.
But i think this is as far as I want to take this WRX... I just want to make sure it has everything it needs. Thanks for the help in advance!
