The BorgWarner EFR B2 74mm turbine housing with 0.83 A/R is a T3 single-scroll assembly that includes a wastegate provision. Tailored for EFR B2 turbine wheels, the 74mm inlet and 0.83 A/R geometry provide a larger physical inlet with single-scroll flow characteristics, suitable when that inlet diameter and A/R pairing are required for a turbo build.
