Vehicle Fitment

This engine and transmission package is a direct fit for:

  • Mazda MX-5 Miata (NA Chassis): 1990, 1991, 1992, 1993

  • Eunos Roadster (JDM): 1989–1993

  • Note: Can be retrofitted into 1994–1997 Miata chassis with minor modifications (1.8L to 1.6L downsize).

Installation & JDM Swap Notes

To ensure a "turn-key" experience, please note the following technical requirements:

  • Long-Nose vs. Short-Nose Crank: These JDM units are typically the preferred "long-nose" crank versions (1991.5+), which eliminated the crank wobble issues found in early 1990 models.

  • Electronics: Swap your original US-spec Air Flow Meter (AFM) and Crank Angle Sensor (CAS) to ensure 100% compatibility with your factory wiring harness.

  • Maintenance: We strongly recommend replacing the Rear Main Seal, Clutch, and Timing Belt while the engine is out of the car for maximum longevity.

  • Transmission: Includes the 5-speed manual gearbox. Inspect shifter bushings and change gear oil (75W-90) before use.

All Star JDM offers limited warranty coverage on eligible used engines and transmissions. Used replacement engines and transmissions are generally covered for 90 days, while used performance engines and performance transmissions are generally covered for 30 days unless otherwise stated on the sales receipt. Rotary engines and parts are sold as-is with no warranty coverage.

The warranty covers eligible internal engine components, engine block, cylinder walls, and cylinder head against cracks or defects. External parts, electronics, accessories, improper installation, negligence, and installation-related failures are not covered.

Warranty claims require a written description, pictures, videos, and a valid report from a certified mechanic. Returned items must be in the same condition as sold, fully assembled, and include all original parts/components included in the sale.
