Technical Description

This complete turbo oil feed and return 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 compatible Holset Super HX30W turbocharger.

The kit combines the pressurized engine to turbo oil supply with the gravity return connection from the turbocharger to the engine oil pan. It includes a -4AN PTFE stainless braided oil feed line, application specific engine side hardware, a full flow Holset turbo oil inlet flange, and a reinforced 3/4 inch NBR oil drain system.

The supplied turbo inlet flange uses a non restricted, full flow configuration for the listed Super HX30W application. Do not add an external oil restrictor unless it is required for the exact turbocharger or confirmed by the turbo manufacturer or GryphonTek.

Key Features

  • Application specific engine oil connection for Early NA, Late NA, and NB Miata models
  • Full flow -4AN PTFE stainless braided oil feed line with a Super HX30W compatible inlet flange
  • Reinforced 3/4 inch NBR gravity return hose with a CNC machined 6061-T6 aluminum drain flange
  • Oil pan return fitting, flange gasket, hose clamps, mounting hardware, and copper sealing washers included
