The Turbosmart 75mm T4 turbine housing with a 1.24 A/R C-frame is a direct-style turbine housing intended for turbocharger builds that accept a T4 flange and a 75mm turbine wheel. Its 1.24 A/R sizing balances spool and top-end flow for medium-to-large forced-induction setups, and the C-frame design simplifies mounting on compatible turbine housings and wheels.
