Oil Drain System for RB30ET Upgrading to T25 / T28 Turbos

Upgrading the Holden VL RB30ET to a Garrett T25 or T28 turbo is a popular option for improved boost response and modern turbocharger reliability.

Because T25/T28 turbos use a different drain flange pattern compared to the original RB30ET Garrett T3, the factory oil drain pipe cannot be reused.

This Gryphontek turbo oil drain hose kit includes a CNC-machined T25/T28 drain flange, a heat-resistant NBR oil drain hose, mild-steel fittings, a 1 mm non-asbestos gasket, and high-tensile bolts—providing a clean, reliable oil return path for both stock-mount and top-mount installations.
