Technical Description

Upgrading to a Garrett G-Series G40, G42, or G45 turbo on your RB20DET, RB25DET, or RB30 engine?

These high-flow turbos demand precise oil control and are always installed on top mount manifolds, which makes the OEM oil feed line unusable or unsafe due to length and pressure mismatch.

This turbo oil feed line kit includes a 2.0mm restrictor oil feed flange, durable 4AN braided PTFE stainless steel line, and a full hardware pack—gasket, bolts, and engine-side adapter—for direct install and correct oil delivery.

‣ Designed for RB20DET / RB25DET / RB30 engines
‣ Compatible with Garrett G40 / G42 / G45 turbos (top mount only)
‣ Includes 2.0mm restricted oil feed flange + gasket + bolts
‣ 4AN pre-crimped PTFE braided stainless steel oil line
‣ Engine-side adapter fitting + copper crush washer
‣ Built to withstand extreme heat and oil pressure
‣ Prevents over-oiling on large frame turbos
‣ Ideal for custom or high-boost builds
‣ Custom hose length available upon request
‣ In stock and ready to ship

Installing a G-Series top mount turbo?
Don’t risk oil starvation or bearing failure—this kit ensures reliable oil flow and perfect fitment, backed by premium materials and hardware.
