Newbie here...... I got a 14 wrx with afully built motor and transmission. I already have a baby blouch turbo on it and it's maxed out at 320hp 325tq so it's time to upgrade. I'm looking for a stock location turbo that can get me as close as I can get to 500hp on pump. I was pointed in the direction of the fp blue or the dom 3.0. Any other recommendations?
