I am running an EJ20G with very little (if any) modifications I just picked up off a guy, I'll be honest I don't really know what is in it right now, I haven't had the time to really find out, however one thing I do know is it doesn't have a BOV/BPV whatsoever... I really don't want to ruin my turbo as that is one of the last things i want to upgrade. I was wondering if anybody had any suggestions as to what I could throw in there that will be able to support some future mods I plan on doing to the vehicle as well.
