Technical Description

This turbo oil feed 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 engine-side connection hardware, flexible -4AN PTFE oil feed line and Garrett-specific 1.0 mm restrictor fitting required for the conversion.

Garrett GT28R and GT30R turbochargers use a different oil inlet connection from the original Subaru TD04, TD05H and IHI VF-Series turbochargers. This kit replaces the factory-style turbo oil feed components with a flexible braided line configured for the applicable Subaru engine-side oil supply and Garrett turbo inlet.

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 can vary by engine code, model year, market and engine conversion history. Select the option by inspecting the installed engine-side oil routing rather than relying on EJ20 or EJ25 displacement alone.

Key Features

  • Oil feed conversion for supported stock-location Garrett GT28R and GT30R installations
  • -4AN PTFE oil feed line with a 304 stainless steel outer braid
  • Garrett turbo inlet fitting with a 1.0 mm restrictor
  • Available with AVCS or Non-AVCS engine-side connection hardware

Installation Notes

This product covers the turbo oil feed side only. It does not include an oil drain pipe or return hose and is not designed for rotated turbo setups, original Subaru TD04 / TD05H / VF-Series turbochargers or journal-bearing turbochargers with different oil requirements.
