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 Garrett T3 T4 turbocharger.

The oil feed system combines an application specific engine fitting, a flexible -4AN PTFE stainless braided line, and a Garrett T3 T4 turbo oil inlet fitting with an integrated 2.0mm restrictor.

The gravity return system includes a 6061-T6 aluminum T3 T4 drain flange, reinforced 3/4-inch NBR hose, Interface N-8092 gasket, oil-pan return fitting, clamps, and installation hardware.

Early NA models use the exhaust side engine oil port with a direct fit M10 adapter. Late NA and NB models take the turbo oil supply from the oil pressure sensor location and use a 1/8 BSPT sensor tee. Select the application that matches the installed engine and actual oil feed source.

Key Features

  • Complete pressurized turbo oil feed and gravity return plumbing package
  • Application specific engine oil fitting for Early NA, Late NA, and NB configurations
  • -4AN PTFE oil feed line with a Garrett T3 T4 2.0mm restrictor fitting
  • 6061-T6 aluminum drain flange with reinforced 3/4-inch NBR return hose
