Technical Description

This turbo oil drain hose 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 turbocharger.

The kit provides the gravity return connection from the turbocharger center housing to the engine oil pan. It includes a Garrett GT Series drain flange, reinforced 3/4-inch NBR oil hose, oil pan return fitting, gasket, clamps, and mounting bolts.

A turbo oil drain must maintain a free downward path to the oil pan. Correct turbo orientation, hose routing, and oil pan fitting position are required to reduce drain restriction and oil back pressure at the turbocharger center housing.

Key Features

  • CNC machined 6061-T6 aluminum drain flange for Garrett GT25R GT28R applications
  • Reinforced 3/4-inch NBR hose for the turbo gravity return system
  • Interface N-8092 non-asbestos gasket with clamps and mounting bolts
  • Oil pan return fitting supplied for naturally aspirated to turbo conversions

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