im still in the break in period of my wrx sedan.. i've about 350 miles on it. when im driving and rpms are in the 2500-3000 range, i hear a small whirring sound. its probably a newbie question, but is that the turbo i hear? or.. something else?

 

saweeeet then... yeah haha it is definitely sexy.
but if not tho i hope it aint nothin bad.
