Technical Description

This turbo oil feed line kit is designed for Mazda MX-5 Miata NA (MK1) and NB (MK2/MK2.5) models being converted from naturally aspirated to turbo using a Holset HX30 or HX35 turbocharger.

The kit uses a flexible -4AN PTFE stainless braided hose to connect the engine oil supply to the turbocharger. A Holset specific non restricted oil inlet adapter and application specific engine side fitting are supplied according to the selected Miata model.

This kit is configured without an external oil restrictor for the listed HX30 and HX35 applications. Do not install an additional restrictor unless required by the turbo manufacturer or confirmed by GryphonTek.

Key Features

  • Non restricted turbo oil inlet adapter for the listed Holset HX30 and HX35 applications
  • Flexible -4AN PTFE hose with protective 304 stainless steel braid
  • Application specific engine fitting for Early NA, Late NA, or NB models
  • Complete pressurized oil supply connection from the engine to the turbocharger
