Technical Description

Oil Drain System for RB20 / RB25 / RB30 Upgrading to Garrett T25 / T28

The Nissan RB20DET, RB25DET, and RB30 platforms are frequently upgraded with Garrett T25 / T28 turbos for improved spool and daily-driveable power gains.

When changing to a different turbocharger—or converting an RB30 N/A engine to turbo—a new oil drain solution is required, as turbo position, flange pattern, and hose routing differ from the factory setup.

This Gryphontek turbo oil drain hose kit includes a CNC-machined T25/T28 drain flange, heat-resistant NBR oil drain hose, mild-steel fittings, a 1 mm non-asbestos gasket, and high-tensile bolts.

Engineered for RB-series vibration, temperature, and RPM demands, it provides a clean, reliable oil return path for both stock-mount and top-mount turbo configurations.

Key Features

‣ Application: Nissan RB20DET / RB25DET / RB30 — Skyline R32 / R33 / R34 & RB30 turbo conversions
‣ Turbo Compatibility: Garrett T25 / T28 journal-bearing turbos
‣ Upgrade-Oriented Design: Required when switching to a different turbocharger or relocating turbo position
‣ Hose Construction: High-temperature NBR oil drain hose suitable for high-RPM turbo applications
‣ Flange Material: CNC-machined 6061-T6 aluminum T25 / T28 drain flange
‣ Fittings: Mild-steel oil drain fittings with reliable sealing for inline-six vibration
‣ Gasket: Interface N-8092 1 mm non-asbestos gasket
‣ Hardware: Stainless hose clamps + class 8.8 bolts
‣ RB Upgrade Ready: Works for RB20/RB25 turbo upgrades and RB30 N/A → turbo conversions
‣ Performance Benefit: Ensures consistent oil evacuation under boost, extended RPM, and high-temperature driving
‣ Custom Length Option: Hose length can be customized to suit different turbo placements, supporting both stock-mount and top-mount configurations

  • 6061-T6 CNC-machined T25/T28 drain flange

A Required Oil Drain Solution When Upgrading to Garrett T25 / T28

Changing to a different turbocharger on an RB-series engine requires the correct oil return system to prevent CHRA oil pooling and smoking.
This Gryphontek kit provides the proper flange, hose, and hardware to support a clean, leak-free oil drain layout for T25/T28 turbo upgrades.
