well to the average person they would say yes...However, I have owned both an SRT-4 and an STi, had it on both, and brand new they both accumulated the same amount.
i have a little in my seperator over the last 3 months. i havnt hit boost tho so i was just wonderin.
Instead of running a oil seperator I just put a one way check valve thats meant for a brake booster. I saw it in a magazine.
