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

‣ Hardware: Stainless hose clamps + class 8.8 bolts
