Technical Description

Fitting a Garrett GT37R, GT40R, GT42R, or GT45R turbo to your Holden VL Commodore RB30ET?

These large-frame GT turbos require a 2.0mm restrictor flange and are only suited for top mount configurations. The factory oil feed line simply won't fit or deliver the correct oil flow.

This turbo oil feed line kit solves those issues with a 4AN braided PTFE stainless hose, a CNC-machined oil feed flange with integrated restrictor, non-asbestos gasket, and all required bolts and engine-side fittings. No adapters, no leaks—just bolt it on and go.

‣ Application: Holden Commodore VL RB30ET engine
‣ Compatible with Garrett GT37R / GT40R / GT42R / GT45R turbos
‣ For top mount turbo setups only
‣ Includes 2.0mm restrictor flange, gasket, and bolts
‣ 4AN pre-crimped PTFE braided stainless oil feed line
‣ Includes engine-side fitting and crush washer
‣ Designed for correct flow, fitment, and heat resistance
‣ Custom-length hose option available
‣ In stock and ready to ship

Don't let oil line issues compromise your high-power GT turbo build.
This kit delivers the correct restrictor size, proper sealing, and the durability your RB30ET needs for reliable top mount performance.
