This Turbosmart B‑frame T3 66mm turbine housing with 0.82 A/R pairs a B‑frame inlet with a T3 outlet and a 66mm throat to balance spool and peak flow for medium to large turbochargers. It’s intended for custom turbo systems where that A/R and flange combination helps tune exhaust pulse timing and overall boost characteristics.
