Nissan TD42 GU GQ + Holset HX30 HX35 Turbo Oil Drain Hose Kit

High-Flow Oil Drain System for TD42 Running Holset HX30 / HX35 Turbos

The Holset HX30 and HX35 are well-known high-flow turbo upgrades for the Nissan TD42 diesel engine, offering stronger boost capability, improved airflow, and excellent durability for towing and off-road builds.

Whether you are replacing aging factory drain hardware on a TD42 GU or installing a complete drain system on a TD42 GQ N/A turbo conversion, a proper oil return setup is essential—especially for high-flow Holset CHRAs that circulate a larger volume of oil.

This Gryphontek turbo oil drain hose kit features a CNC-machined Holset drain flange with an enlarged bottom port, a large-diameter NBR oil drain hose, steel fittings, a 1 mm non-asbestos gasket, and high-tensile hardware.

Designed to handle the vibration, heat, and heavy diesel oil viscosity associated with TD42 engines, it ensures clean, unrestricted oil evacuation for HX30 and HX35 high-flow turbo systems.
