Anyone care to expain the Stages for the EJ20?
I'm sureI'm not the only one who is sick of reading posts about Stage * WRX's.
In my one year of experience, their isn't any clear cut definition of which stage consists of which mods. For example Cobb's stage one includes a reflash and nothing else, claiming 260 hp. Whereas Vishnu's stage one includes a reflash, power pulley, up pipe and turbo back exhaust.
Can anyone clear up this conundrum or is this just something we all have to deal with? I've read posts about someone getting a certain 1/4 mile time with a "Stage 4" WRX. But I have no Idea what that means. I guess I can call my STi scoop a stage one by industry standards. Please Help!

....uummm...I think Sony is responsible for all the confusion
There is nothing to clear up...it is all pea soup and will always be.
It cannot be any clearer than it is because there is no and never will be any set standard, so get over it and don't waste any more time tinking about it. I don't.

Cobb:
Stage 1 = reflash no mods
Stage 2 = reflash and turboback (actually just DP cat removed)
Stage 2.5 = Stage 2 plus VF34/30, STi injectors
Stage 3 = Stage 2.5 plus Cobb's TMIC (or so rumored, due Spring 04)
Vishnu:
Stage SubZero = reflash no mods
Stage Zero = Reflash + uppipe/pulley
Stage 1 = Zero + turboback
Stage 2 = 1 + VF30/injectors/fuel pump
Stage 3 = some totally custom job that will rule
TurboXS
Stage 1 = UTEC
Stage 2 = 1 + Turboback
Stage 3 = 2 + TMIC + Uppipe
Stage 4 = UTEC, turboback, VF30, uppipe, injectors, fuel pump
Stage 4++ = 4 + TMIC
****
It's all relative.
