Oil Drain System for RB20 / RB25 / RB30 with Garrett T3 / T4 Turbos

Garrett T3 / T4 turbos are a proven upgrade for RB20DET, RB25DET, and RB30 engines, delivering strong airflow and excellent power potential.

Although T3/T4 turbos share the same drain flange pattern as the factory RB turbo, the original oil drain pipe on aging RB engines often becomes brittle, restricted, or begins to seep oil after years of heat cycles.

When replacing the old turbocharger or switching to a T3/T4 setup, a new oil drain hose is recommended to ensure proper routing, unrestricted oil flow, and leak-free operation.

This Gryphontek turbo oil drain hose kit includes a CNC-machined T3/T4 drain flange, high-temperature NBR oil drain hose, mild-steel fittings, a 1 mm non-asbestos gasket, and high-tensile hardware for a reliable, clean oil return path.

A Fresh Oil Drain Solution for T3/T4-Equipped RB Engines

Even though T3/T4 turbos share the same drain flange as OEM RB turbos, aging factory drain pipes and updated turbo placement often require a new, properly-routed oil return system.
This Gryphontek kit ensures a clean, unrestricted, leak-free oil drain path for T3/T4 turbo upgrades.

⚙️ Support your RB turbo upgrade with a reliable oil drain system engineered for T3 / T4 fitment.
