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 water-cooled Mitsubishi TD04, TD04L, or compatible TD04HL turbocharger.

The kit provides the coolant hoses and fittings required to connect the turbo center housing to the Miata cooling circuit through the thermostat case and mixing manifold connections. NA applications use 8 mm / 5/16 inch coolant hose, while NB applications use 10 mm / 3/8 inch hose.

TD04 family center housings are available with different coolant-port threads. Select M12×1.25 or M12×1.5 according to the actual thread in the installed turbocharger.

Key Features

  • Application specific 8 mm NA or 10 mm NB coolant hose configuration
  • Selectable M12×1.25 or M12×1.5 TD04 family water port fittings
  • Reinforced NBR coolant hoses for flexible engine bay routing
  • Supplied with coolant adapters, copper washers, clamps, and installation hardware
