Technical Description

Oil Drain Solution for RB30ET Garrett G-Series Turbo Upgrades

When upgrading the Holden Commodore VL RB30ET to a Garrett G-Series G40, G42, or G45, a new oil drain solution is required to suit the larger turbocharger and revised installation layout.

These larger-frame G-Series turbos are commonly used in high-power RB30ET builds, where stable and consistent oil return is essential for long-term reliability.

This Gryphontek turbo oil drain hose kit is designed for Garrett G-Series top-mount applications, featuring a CNC-machined drain flange, a large-diameter high-temperature NBR oil drain hose, mild-steel fittings, a 1 mm non-asbestos gasket, and high-tensile hardware.

It provides a clean, gravity-fed oil return path suitable for RB30ET top-mount G40 / G42 / G45 builds.
