A Turbosmart 70mm turbine housing with a T4 divided flange and 1.28 A/R, intended for compatible turbocharger assemblies. The larger 70mm turbine size and 1.28 A/R are chosen to influence spool and top-end flow in installations that accept a T4 divided outlet. Use this housing to modify turbine characteristics without changing the turbo center section itself.
