Technical Description

The definitive all-in-one oiling solution for your IHI VJ35 conversion. Converting a naturally aspirated Miata to use the Mazdaspeed-spec VJ35 turbo requires a perfectly balanced lubrication loop. Most DIY projects fail due to mismatched fittings or restricted drainage that leads to "Blue Smoke." This GryphonTek Signature Series Kit provides a coordinated, professional-grade system that handles both high-pressure delivery and unrestricted return—tailored specifically to your Miata’s chassis year.

  • Balanced Flow Control: Features a precision 1.8mm restricted feed path to prevent bearing flooding, paired with a high-flow IHI-specific drain to stop back-pressure 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: Combines motorsport-grade PTFE braided feed lines with reinforced NBR return paths to survive the intense radiant heat of the Miata's "Hot Side."
  • Harmonic Defense: Flexible plumbing architecture absorbs B6/BP engine vibrations, preventing the fatigue cracks common in rigid factory hard pipes.
