EcotecMiata Complete Swap Kit V3.1

  • Kit includes the following individual components:

    - Oil Pan kit

    - Engine Mount kit

    - Transmission Adapter kit

    - Cooling System kit

    - Air Intake Kit

    - Oil pressure sensor adapter (NB also includes coolant temp sensor)

    This complete swap kit is designed for the enthusiast that wants entry level supercharged or turbocharged 1.8 Miata performance, without all the issues that surround those builds. We generally suggest the LE5 engine, for its broad torque curve. This engine best simulates the low RPM torque of a M62 supercharged 1.8L engine, while giving horsepower numbers similar to those achieved with a basic bolt-on entry level turbo system. It, however, has none of the short comings of either of those boosted solutions. Upgraded radiators are not needed, external oil coolers are not needed, no worry of turbo bolts coming loose, no need to carry a spare supercharger belt, no intense underhood temperatures. Simply enjoy the pleasures of a light, nimble Miata with a much needed boost in power. In the complete kit we also include an oil pressure sensor adapter to allow you to install your existing Miata pressure sensor into the Ecotec engine. For NB applications we also include a coolant temp sensor that connects to the OE Mazda coolant temp gauge on the dash.
