Upgrading your Subaru EJ20 or EJ25 engine to a Garrett GT28R or GT30R bolt-on turbo?
The stock oil feed hard line won’t match the new turbo’s inlet thread, and restrictor sizing becomes critical to avoid oil flooding or starvation.
This kit is specifically engineered for GT28R / GT30R conversions using factory-style stock mount.
It includes a 1.0mm restrictor fitting, braided PTFE hose, and all hardware to safely supply your turbo with the correct oil volume and pressure.
‣ Engine compatibility: Subaru EJ20 / EJ25
‣ Supports stock mount Garrett GT28R / GT30R ball bearing turbos
‣ Includes 1.0mm restrictor (correct sizing for Garrett BB turbos)
‣ 4AN pre-crimped PTFE braided oil feed line
‣ Turbo-side and engine-side fittings included
‣ Optional AVCS line (select if needed)
‣ Engine banjo bolt with copper crush washer
‣ Custom hose length available
‣ In stock, ready to ship
Whether you're running a GT28R or GT30R upgrade, this kit gives you everything needed for a secure oil feed connection—no more mismatched fittings or wrong restrictor sizes.
