The Garrett G40 turbine housing kit for standard rotation includes a divided T4 flange, V-band outlet and a 1.06 A/R. The larger A/R adjusts exhaust flow and spool behavior for compatible G40 installations, affecting response and peak characteristics. Verify mating compressor housing, manifold compatibility and rotation direction before choosing this housing for a turbo rebuild or custom application.
