Technical Description

Precision oil control for your Miata T3/T4 conversion. Upgrading your naturally aspirated Miata to a classic Garrett T3, T4, or T3/T4 Hybrid journal-bearing turbo is a proven path to high-horsepower builds, but managing oil pressure is critical for longevity on the Mazda B6/BP block. This GryphonTek Signature Series Kit eliminates the sourcing nightmare by providing the exact year-specific Miata block adapter and the calibrated 2.0mm restrictor required to protect your journal bearings from high-pressure seal blow-by.

  • Precision 2.0mm Metering: Calibrated restrictor prevents journal-bearing flooding, safeguarding Miata builds from the common "Blue Smoke" issues and oil blow-by at high RPM.
  • Miata Year-Specific Integration: Precision adapters bridge factory oil sources (M10 or 1/8 BSPT) to Garrett threads, preventing block thread damage common with "universal" NPT fittings.
  • Extreme Thermal Resilience: Motorsport-grade PTFE braided stainless steel survives the intense radiant heat of high-power Miata exhaust manifolds without hardening.
  • Harmonic Defense: Flexible -4AN architecture absorbs B6/BP engine vibrations, eliminating the fatigue cracks common in rigid factory hard-pipes.
