Technical Description
The definitive all-in-one oiling loop refresh for your Garrett upgrade. Upgrading your naturally aspirated Mazda Miata to a Garrett GT25R or GT28R series turbocharger requires a fundamental shift in lubrication logic. Dual ball-bearing cartridges demand strict pressure regulation (1.0mm) paired with high-volume drainage to prevent seal failure. This GryphonTek Signature Series Kit provides a coordinated, professional-grade loop that handles both high-pressure delivery and unrestricted return, tailored specifically to your Miata’s chassis year.
