Technical Description

The essential cooling infrastructure to finalize your IHI VJ35 conversion. Converting a naturally aspirated Mazda Miata to use the water-cooled Mazdaspeed-spec VJ35 turbocharger requires a reliable bridge to the engine’s coolant circuit. This GryphonTek Signature Series Kit provides a coordinated package of reinforced hoses and specific fittings required to bridge the Miata’s Thermostat Case and Mixing Manifold to the VJ35 core—ensuring your turbo stays healthy and your build stays on the road.

  • Precision Barb Integration: Pre-matched banjo eyes bridge factory 8mm or 10mm Thermostat Case sources to VJ35 threads, eliminating sourcing guesswork and part-hunting.
  • Industrial NBR Construction: Reinforced NBR hoses remain flexible under extreme thermal cycles and resist cooling system pressure spikes.
  • Vibration Fatigue Defense: Flexible plumbing architecture absorbs B6/BP engine harmonics, preventing the fatigue cracks common in rigid custom pipes.
  • Zero-Leak Interface: Includes copper washers and clamps for a permanent, high-pressure seal.
