Technical Description

This complete turbo oil feed and return line kit is designed for turbocharged Subaru EJ20 and EJ25 engines using supported stock-location, bolt-on Garrett GT28R or GT30R ball-bearing turbocharger conversions. It provides the pressurised oil feed and gravity-return components required to connect the Garrett turbo to the applicable Subaru engine-side oil system.

Garrett GT28R and GT30R turbochargers use different oil inlet and drain connections from the original Subaru TD04, TD05H and IHI VF-Series turbochargers. This kit combines a flexible -4AN PTFE oil feed line and 1.0 mm turbo inlet restrictor with a Garrett-specific drain pipe, reinforced NBR return hose and installation hardware.

Choose the Correct Engine Configuration

  • Non-AVCS: For engines using the corresponding direct turbo oil feed arrangement.
  • AVCS: Includes the required T-fitting and secondary oil line for the applicable AVCS oil feed layout.

Important: AVCS equipment varies by engine code, model year, market and engine conversion history. Select the configuration by inspecting the installed engine-side oil routing rather than relying on EJ20 or EJ25 displacement alone.

Key Features

  • Complete oil feed and gravity-return system for supported bolt-on Garrett conversions
  • -4AN PTFE braided oil feed line with a Garrett 1.0 mm restrictor fitting
  • Garrett-specific electro-black steel drain pipe with reinforced NBR return hose
  • Available with AVCS or Non-AVCS engine-side oil feed hardware

Installation Notes

This kit is intended for supported stock-location, bolt-on Garrett GT28R and GT30R ball-bearing turbo conversions. It is not designed for rotated turbo installations, original Subaru TD04 / TD05H / VF-Series turbochargers or journal-bearing turbochargers with different oil requirements.
