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 compatible Garrett GT25R or GT28R ball bearing turbocharger.

The kit provides the pressurized oil supply connection from the engine to the turbocharger. It combines an application specific engine oil fitting, a flexible -4AN PTFE stainless braided line, and a Garrett turbo inlet fitting with an integrated 1.0mm restrictor and -4AN connection.

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.

Key Features

  • Application specific engine fitting for Early NA, Late NA, and NB oil feed arrangements
  • Flexible -4AN PTFE oil feed line with a 304 stainless steel outer braid
  • Garrett turbo inlet fitting with an integrated 1.0mm restrictor
  • Configured for the listed Garrett GT25R and GT28R ball-bearing turbo applications

Need help confirming your vehicle application or turbo setup? Refer to the Mazda Miata NA/NB Turbo Oil & Water Line Fitment Guide before ordering.
