is that td06 on an sr20? how does that work.... ive been toying with the idea lately. i do miss my laggy boost ^^ this ballbearing crap is for gays also, gaz, just noticed this is twinscroll, are you using a tuned twinscroll manifold? thatll help you out a few hundred RPM. i still think youll have trouble getting this doing much before 5k though
