Technical Description
The definitive all-in-one plumbing refresh for your Garrett upgrade. Upgrading a naturally aspirated Miata to a high-value Garrett GT25R or GT28R series turbocharger requires a balanced life-support loop. This GryphonTek Signature Series Kit is the only complete system that handles high-pressure delivery, unrestricted drainage, and critical water cooling in one professional package—tailored specifically to your Miata’s chassis year.

- Year-Specific Integration: Pre-matched block adapters bridge factory oil and coolant sources to Garrett threads, eliminating sourcing guesswork and part-hunting.
- Ball-Bearing Pressure Protection: Integrated 1.0mm precision restrictor prevents high-pressure flooding, safeguarding internal seals from blow-by and blue smoke.
- Extreme Thermal Resilience: Reinforced high-temp NBR and PTFE construction survives intense manifold radiant heat and resists cooling system pressure spikes.
- Harmonic Defense: Flexible plumbing architecture absorbs B6/BP engine vibrations, preventing the fatigue cracks common in rigid custom pipes.
