Agreed.
Big money teams around here run them, and have seen offhand good results with the 7163 on a T4 Fullrace TS (on both a VE and DE heads). People hear T4 and think Diesel turbo, but this damn thing spools even better than a GTX3076/71R with even more headrooom up top! Transient response is on another planet!
The GTX series aint bad, but the EFR brings a whole new world to things. Just wish they didn't come with a shitty plastic BOV and subpar wastegate diaphragm
