Technical Description

This turbo water 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 water-cooled Garrett GT25R or GT28R turbocharger.

The kit connects the Miata cooling circuit to the turbocharger center housing using reinforced NBR coolant hoses, Garrett specific turbo water port adapters, vehicle side barb fittings, copper sealing washers, clamps, and installation hardware.

NA models use 8 mm / 5/16-inch coolant hoses, while NB models use 10 mm / 3/8-inch hoses. Select the application that matches the installed vehicle side coolant connections.

Key Features

  • Connects the Miata thermostat case and mixing manifold coolant points to the turbocharger center housing
  • Application specific 8 mm NA or 10 mm NB coolant hose configuration
  • Garrett specific turbo water port adapters with vehicle side barb fittings
  • Reinforced NBR coolant hoses supplied with sealing washers, clamps, and installation hardware
