I'm looking for advice on the 5mt. I've been lurking for a while and recently got a 2005 obxt. I've been accumulating stage3 parts for BNR16G turbo support while shopping for a "build off". I've seen differing opinions on the site saying that stock trannies can hold up to 400hp and others saying stage2 is the limit. Should I upgrade the clutch? Any recommendations for specific clutch packages?
