Technical Description

Modern performance meets year-specific precision. Upgrading your Miata to the Garrett GBC20 or GBC22 provides elite-tier response in an oil-cooled package, but these modern journal-bearing cartridges require exact pressure regulation. This GryphonTek Signature Series Kit is the professional foundation, supplying the exact adapter and calibrated flow path required for your Miata’s specific engine year—eliminating the risk of stripped block threads and blue smoke.

  • Anti-Strip Block Adapters: Precision-matched fittings prevent damage to the block and ensure a zero-leak seal for every Miata generation.
  • GBC Calibrated Restrictor: Prevents high-pressure flooding to the bearing cartridge, safeguarding GBC internal seals from blow-by and exhaust smoke.
  • Thermal Radiant Defense: High-temp PTFE braided stainless steel survives intense manifold heat without becoming brittle or leaking.
  • Harmonic Defense: Flexible -4AN architecture absorbs B6/BP vibrations, preventing the fatigue cracks common in rigid pipes.
