Greddy Turbocharger Oil Line

GReddy Turbocharger Oil Lines: Factory-Engineered Lubrication for TD & TZ Turbos

When you install a GReddy turbocharger, every supporting component in the system matters — and the oil feed line is no exception. A turbocharger spins at tens of thousands of RPM, and uninterrupted, properly pressurized oil flow is what keeps the center cartridge alive. GReddy's turbocharger oil lines are purpose-built replacement and upgrade components designed specifically to match the exacting demands of their own turbo hardware.

Built Around GReddy's Own Turbo Platforms

Trust Company Ltd. is a Japanese automotive aftermarket company widely known for its sub-brand GReddy and the turbochargers developed under it. Founded in Japan in 1977, Trust manufactured automotive performance products that have since become benchmarks in the forced-induction world. That decades-long heritage in turbocharger design is precisely why GReddy's oil lines carry so much credibility — they are engineered by the same company that built the turbos themselves.

GReddy's replacement oil feed lines are designed for their TD and TZ turbocharger series, featuring JDM 1/8PF (1/8 BSP Flare) female ends. These lines are available in 500mm (19.7"), 600mm (23.6"), and 800mm (31.5") lengths, with compatible replacement fittings sold separately — including hose union adapters and M10xP1.25 banjo-type unions — giving builders the flexibility to route oil supply cleanly in a variety of engine bays.

Why Proper Turbo Oil Lines Matter

A turbocharger's journal bearings or ball bearings depend entirely on a steady stream of clean, pressurized engine oil for lubrication and cooling. An undersized, kinked, or poorly routed oil feed line can starve the turbo of lubrication under boost, leading to premature bearing wear or catastrophic failure. Using lines engineered to match a specific turbo's inlet port size and flow requirements — as GReddy's replacement lines are — eliminates the guesswork that comes with adapting generic AN fittings to a turbo that may require specific flow rates or connection geometries.

With over 25 years of performance turbocharger experience, GReddy is able to offer the best combination of response and peak power — and that engineering depth carries through to even the supporting plumbing components. When GReddy specifies a particular line length and fitting style for their TD and TZ turbos, it reflects real-world development and testing, not guesswork.

A Legacy of Forced-Induction Expertise

GReddy turbocharger kits are engineered for vehicle-specific applications, allowing each kit to be tailored for the best match in performance, drivability, and ease of installation. That same philosophy extends to their oil line offerings: the correct line for a specific turbo model ensures proper oil delivery without relying on improvised fittings or mismatched hardware. Whether you're refreshing an aging GReddy TD05, TD06, or TZ-series build, or setting up a new install, factory-spec oil lines keep the system performing as GReddy intended.

For enthusiasts who have invested in a GReddy turbo system, pairing it with GReddy's own turbocharger oil lines is the straightforward path to a reliable, properly lubricated setup. Browse the full selection to find the right length and configuration for your application.
