Technical Description

The definitive oiling solution for your oil-cooled Garrett GBC upgrade. Upgrading your naturally aspirated Miata to a Garrett GBC20-300 or GBC22-350 provides modern response without the complexity of a cooling loop. This GryphonTek Signature Series Kit is the professional system that handles both high-pressure delivery and unrestricted drainage in one coordinated package, tailored specifically to your Miata’s chassis year.

  • Year-Specific Integration: Precision adapters bridge factory oil sources to GBC threads, eliminating sourcing guesswork and preventing block thread damage.
  • GBC Calibrated Flow: Features a precision restrictor matched for GBC journal bearings to prevent seal blow-by and "Blue Smoke" issues.
  • Extreme Thermal Resilience: Motorsport-grade PTFE braided feed lines and reinforced NBR drainage paths 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.
