The BorgWarner EFR B2 80mm turbine housing with 0.92 A/R is a T4 twin-scroll assembly supplied with a wastegate provision. Intended to pair with EFR B2 turbine wheels, the 80mm inlet and 0.92 A/R exhaust geometry combine larger inlet diameter with twin-scroll T4 flow management for builders matching turbine housing characteristics to their turbo setup.
