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 Garrett GBC20-300 or GBC22-350 turbocharger.

The kit provides the gravity return connection required to route oil from the GBC center housing to the engine oil pan. It includes a GBC pattern billet aluminum drain flange, reinforced NBR oil hose, Interface N-8092 gasket, oil pan return fitting, stainless steel clamps, and mounting hardware.

Turbo oil drain performance depends on the installation geometry. The turbo center housing and drain hose must be positioned to maintain a continuous downward oil path without kinks, low points, collapsed sections, or upward routing.

Key Features

  • GBC pattern oil drain flange for Garrett GBC20-300 and GBC22-350 turbochargers
  • CNC machined 6061-T6 billet aluminum flange construction
  • Reinforced oil resistant NBR hose for flexible gravity return routing
  • Supplied with an Interface N-8092 gasket, oil pan fitting, clamps, mounting bolts, and installation hardware
