Technical Description
Precision lubrication for high-performance ball-bearing upgrades. Upgrading your Subaru EJ20 or EJ25 to a Garrett GT28R or GT30R requires more than just a bolt-on fit; it demands precise oil pressure management. Garrett’s dual ball-bearing cartridges are highly sensitive to over-oiling. This GryphonTek Signature Series Kit is the professional-grade solution, featuring a calibrated 1.0mm restrictor and motorsport-grade PTFE lines to ensure your turbo receives metered flow without compromising internal seals.

GryphonTek Engineering
- Ball-Bearing Pressure Protection: Features a high-precision 1.0mm restrictor fitting. This prevents high-pressure oil spikes from overwhelming internal Garrett seals, effectively eliminating Blue Smoke and oil blow-by.
- Seamless GT Conversion: Replaces the mismatched factory hard lines with a flexible -4AN PTFE system. Specifically engineered to bridge the gap between the EJ engine block and Garrett’s specific oil inlet threads.
- Thermal Radiant Resilience: The motorsport-grade PTFE core, wrapped in 304 stainless steel braiding, survives the intense radiant heat trapped in the Subaru’s compact engine valley without becoming brittle.
- "Turbo Killer" Filter Delete: Mandatory block-side logic included to bypass the clog-prone factory mesh filter, ensuring a clean and constant oil supply for your Garrett investment.
