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 Mitsubishi TD04, TD04L, or compatible TD04HL turbocharger. It establishes a gravity oil-return path from the turbo center housing to the engine oil pan.

The TD04 family billet aluminum drain flange mounts to the turbo oil outlet and connects to a reinforced 3/4-inch NBR hose. The supplied oil-pan return fitting provides the engine side connection, while the flexible hose allows the drain route to be positioned around the manifold, engine mount, and turbo location of a custom conversion build.

Installation requires modification of the oil pan for the supplied return fitting. Confirm the turbo drain flange pattern, center housing orientation, oil-pan fitting location, internal clearance, and available hose route before drilling or tapping the oil pan.

Key Features

  • TD04 family drain connection: Uses a billet aluminum flange configured for compatible Mitsubishi TD04 and TD04L center housings.
  • 3/4-inch gravity return: Reinforced NBR hose provides a large oil-return path from the turbo to the oil pan.
  • Flexible installation routing: The hose can be positioned around the manifold and turbo location of a custom NA/NB conversion.
  • Complete drain side hardware: Includes the turbo flange, gasket, oil-pan fitting, hose clamps, and mounting bolts.
