Technical Description

The definitive all-in-one plumbing fix for your classic Garrett upgrade. Upgrading a naturally aspirated Miata to a Garrett T25 or T28 journal-bearing turbocharger requires a perfectly 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: Precision adapters bridge factory oil and coolant sources to Garrett threads, eliminating sourcing guesswork and preventing block thread damage.
  • Balanced Flow Control: Precision 1.8mm restricted feed prevents bearing flooding, paired with a high-flow drain to stop back-pressure and "Blue Smoke."
  • Extreme Thermal Resilience: Combines PTFE braided feed lines with reinforced NBR cooling/drainage paths to survive intense "Hot Side" radiant heat.
  • Harmonic Defense: Flexible plumbing architecture absorbs B6/BP engine vibrations, preventing the fatigue cracks common in rigid factory pipes.

Why Upgrade / Why Choose +

A Garrett T25/T28 conversion is only as reliable as its plumbing interface. Piecing together a system from universal fittings is a high-risk gamble: without the mandatory 1.8mm restrictor, excessive pressure forces oil into your exhaust; without the exact 8mm (NA) or 10mm (NB) coolant source match, your installation will leak or carbonize (coke) bearings.

The GryphonTek Complete Kit eliminates these risks by providing the exact year-specific hardware required for a zero-leak seal. We’ve mapped the Miata’s geometry to ensure a "snake-fit" installation that clears all obstructions. By replacing improvised plumbing with our Coordinated System, you protect your turbo investment and spend more time driving and less time chasing individual fittings.
