Technical Description
Precision oil control for the classic T-Series conversion. Upgrading your naturally aspirated Miata to a Garrett T25 or T28 journal-bearing turbo is a proven path to reliable power, but managing oil pressure is the single most important factor for turbo longevity. This GryphonTek Signature Series Kit eliminates the sourcing nightmare by providing the exact year-specific block adapter and the calibrated 1.8mm restrictor required to protect your journal bearings from high-pressure blow-by.

- Precision 1.8mm Metering: Calibrated restrictor prevents journal-bearing flooding, safeguarding internal seals from oil blow-by and the common "Blue Smoke" issues in DIY builds.
- Anti-Strip Year Integration: Precision adapters bridge factory oil sources to Garrett threads, eliminating sourcing guesswork and preventing permanent block thread damage.
- Extreme Thermal Resilience: Motorsport-grade PTFE braided stainless steel survives the intense radiant heat of the Miata's "Hot Side" without hardening.
- Harmonic Defense: Flexible -4AN architecture absorbs B6/BP engine vibrations, eliminating the fatigue cracks common in rigid factory pipes.
