Nissan RB20DET RB25DET RB30 + TD05H TD06 Turbo Oil Drain Hose Kit

Oil Drain System for RB20 / RB25 / RB30 Running TD05H / TD06 Turbos

The Nissan RB-series engines—RB20DET, RB25DET, and RB30—are widely upgraded with Mitsubishi TD05H and TD06 turbos thanks to their strong mid-range response and excellent top-end airflow.

Whether replacing old OEM drain hardware on a factory-turbo RB20/RB25, or adding a complete oil drain path to an RB30 N/A turbo conversion, a proper oil return system is essential to prevent oil pooling, smoke, and CHRA damage.

This Gryphontek turbo oil drain hose kit includes a TD05H/TD06 CNC-machined drain flange, heat-resistant NBR oil drain hose, mild-steel fittings, a 1 mm non-asbestos gasket, and high-tensile hardware.

Designed for the thermal load, higher RPM operation, and engine movement typical of RB platforms, it provides a clean, reliable oil return path for both stock-mount and top-mount TD05H / TD06 turbo applications.
