Ive driven/worked on wrx's/sti's and almost any performance japanese made import.Yes i do work at a dealership and that has nothing to do with me owning 11 1g's.My fastest bolt on stock turbo 1g ran 27lbs of boost and i got sick of breaking shit(since your asking if any of my cars could go 13's).Are you on the stock turbo?We did a jdm (vr34?) sti turbo upgrade once on a older wrx and it was pretty quick afterwards.Good luck and post what happens with the race with cory and maybe you can run my slow civak eventually since i sent out my turbo out to g-pop shop this morning.
