Technical Description

Running a Garrett GT28R, GT30R, or GT35R ball bearing turbo on your RB20DET, RB25DET, or RB30 engine?
These upgraded turbos require precise oil control—too much pressure can damage the bearing, while the factory oil line won’t fit or deliver correct restriction, especially with top mount manifolds.

This turbo oil feed line kit features a 1.0mm restrictor adapter, a pre-crimped 4AN PTFE braided stainless steel line, and the proper fittings to ensure safe oil delivery to your GT-series turbo.

✅Key Features

‣ Application: RB20DET / RB25DET / RB30 engines
‣ Compatible with Garrett GT28R / GT30R / GT35R ball bearing turbos
‣ Designed for stock mount and top mount setups
‣ Includes 1.0mm restrictor oil feed adapter fitting
‣ 4AN pre-crimped PTFE braided stainless steel oil line
‣ Includes engine-side adapter + copper crush washer
‣ Prevents over-oiling and bearing damage
‣ Reliable, high-heat-resistant solution
‣ Custom hose length available upon request
‣ In stock and ready to ship

Protect your GT ball bearing turbo with the right oil feed system.
This kit gives you everything you need—optimized restriction, strong fittings, and a durable line that fits stock or top mount configurations.

📦 All kits are in stock and ready to go.
