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 Garrett T25 or T28 journal bearing turbocharger.

The kit connects the Miata cooling circuit to the turbocharger center housing using reinforced NBR coolant hoses, Garrett T2 specific water port fittings, vehicle side coolant barb adapters, 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.

This kit is configured for the listed Garrett T25 and T28 journal bearing turbo applications. Confirm the exact turbo model and coolant port configuration before ordering, especially when using an aftermarket T25 T28 style turbocharger.

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 T2 specific turbo water port fittings with vehicle side coolant barb adapters
