Technical Description

Swapping in a Garrett T25 or T28 turbo to your RB20DET, RB25DET, or RB30 engine setup?

The factory oil feed line won't support the turbo's requirements—especially if you're switching to a top mount manifold or chasing boost beyond OEM specs. Incorrect oil pressure can lead to turbo failure.

This turbo oil feed line kit features a 1.8mm restrictor adapter fitting, pre-crimped 4AN braided PTFE line, and all the fittings needed to properly oil your T25 / T28 turbo in both stock and top mount configurations.

‣ Application: Nissan RB20DET / RB25DET / RB30
‣ Compatible with Garrett T25 / T28 turbochargers
‣ Supports stock mount and top mount installs
‣ Includes 1.8mm restrictor adapter fitting
‣ 4AN pre-crimped PTFE braided stainless steel oil line
‣ Includes engine-side adapter + copper crush washer
‣ Reliable oil delivery for journal bearing T25 / T28 turbos
‣ Designed for high-boost and high-temp environments
‣ Custom hose length available on request
‣ In stock and ready to ship

Upgrading to a T25 or T28 turbo on your RB build?
This oil feed kit ensures the correct oil flow and restrictor sizing, with zero fabrication and full support for both stock and aftermarket manifold layouts.

📦 All components are in stock.
