Technical Description

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.

Key Features

‣ Application: Nissan RB20DET / RB25DET / RB30 — Skyline R32 / R33 / R34 & RB30 turbo conversions
‣ Turbo Compatibility: Garrett T3 / T4 turbos
‣ Hose Construction: Heat-resistant NBR oil drain hose for sustained high-temperature use
‣ Flange Material: 6061-T6 CNC-machined aluminum T3/T4 drain flange
‣ Fittings: Mild-steel drain fittings providing secure sealing under inline-six vibration
‣ Gasket: Interface N-8092 1 mm non-asbestos gasket
‣ Hardware: Stainless hose clamps + class 8.8 bolts
‣ Performance Benefit: Supports smooth, unrestricted oil evacuation under boost and extended RPM
‣ Custom Length Option: Hose can be customized to fit various turbo placements (stock-mount or top-mount)

  • NBR turbo oil drain hose
  • 6061-T6 CNC-machined T3/T4 drain flange

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.
