The Turbosmart B‑frame T4 divided 66mm turbine housing with 1.00 A/R is a larger‑flow option that uses a divided inlet and T4 flange to influence turbine response and exhaust scavenging. It’s intended for modified engines and high‑flow turbochargers where a higher A/R helps deliver peak flow at the cost of slightly slower initial spool characteristics.
