Technical Description

The professional foundation for your IHI VJ35 conversion. Transforming a naturally aspirated Miata using the Mazdaspeed-spec IHI VJ35 turbocharger is an excellent choice for responsive boost, but finding compatible plumbing is a notorious hurdle. This GryphonTek Signature Series Kit eliminates the "parts-hunting" nightmare, supplying the exact year-specific block adapter and 1.8mm restricted path required for optimal journal-bearing lubrication.

  • Precision 1.8mm Metering: Calibrated restrictor prevents high-pressure flooding, protecting IHI journal bearings from seal blow-by and "Blue Smoke."
  • Year-Specific Integration: Precision adapters bridge factory oil sources to VJ35 threads, eliminating sourcing guesswork and preventing block thread damage.
  • Extreme Thermal Resilience: Motorsport-grade PTFE braided stainless steel survives intense radiant heat without becoming brittle or leaking.
  • Harmonic Defense: Flexible -4AN architecture absorbs B6/BP engine vibrations, eliminating the fatigue cracks common in rigid custom pipes.
