Technical Description

Oil Drain Solution for RB30ET Large-Frame Garrett GT Turbo Upgrades

When upgrading the Holden Commodore VL RB30ET to a large-frame Garrett GT37R, GT40R, GT42R, GT45R, or GT47R, a revised oil drain setup is required to suit the increased turbo size and output level.

These GT-series turbos are commonly used in high-power RB30ET builds, where stable oil return is critical under sustained boost and load.

This Gryphontek turbo oil drain hose kit is designed for Garrett GT large-frame 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 GT37R–GT47R builds.
