1990 to 1997 Mazda MX-5 Miata EV conversion

The NA Mazda MX-5 Miata is quickly becoming a favorite for electric conversions. It is light, plentiful, and has a stiff power plant frame that makes drivetrain mounting straightforward. The challenge is space, and that is exactly what the RESTOVOLT Fitment Pack solves.

Platform history

Launched for 1990, the NA Miata revived the affordable two seat roadster and became the best selling roadster in history. Its pop-up headlights and simple, balanced chassis make it a modern classic with a large community. Clean examples remain affordable, which makes the platform attractive for builders who want a fun electric car without six figure costs.

Conversion considerations

The power plant frame that ties the transmission to the differential is retained, so drivetrain alignment stays factory accurate. The 5 speed gearbox can stay with an adapter, though many builds go direct to the differential with a compact motor. Space is tight, so modules fill the engine bay, the former fuel tank behind the seats, and the trunk floor. Keep total pack mass under the published limit to preserve the car's 50 to 50 balance.

Weight and packaging

A 35 to 45 kWh pack is the sweet spot. The fuel tank location behind the seats is the safest place for the largest module group. Trunk boxes sit low under a false floor so luggage space remains.

Range and cost bands

Parts run $24,000 to $48,000 with 120 to 190 labor hours. The Miata offers one of the best performance per dollar results in the library. See the full MX-5 Miata EV conversion cost breakdown.
