Precision Engineered parts for your ev conversion
Corona de Tucson, Arizona
Welcome to EVolution Motor Company, where we specialize in precision-engineered hardware for EV conversions. Founded by a mechanical engineer with over 20 years of experience across the defense, aerospace, and autonomous vehicle industries, we bring real engineering discipline to every part we build — modeled, analyzed, and validated before it ever reaches your garage.
Our current lineup centers on the Nissan Leaf EM57 motor platform: a precision adapter plate for Mazda Miata NA/NB manual transmissions, adjustable motor mounts, and a matching transmission mount.
We believe good engineering earns trust faster than marketing claims do. That's why every part we sell is something we've already put on our own vehicles — tested, refined, and ready to work the first time you install it.
If you're building an EV conversion and need hardware you can actually rely on, get in touch — we'd love to talk through your project.
Beyond our own product line, we also offer engineering services to other EV builders and companies — from thermal analysis to component design and validation. If your team needs an engineer who understands EV powertrains, thermal management, and mechanical design at a deep level, we're available for contract work.
Every part is designed from scratch, CAD-modeled, analyzed, prototyped and tested — built to solve a real fitment or performance problem, not just fill a catalog. Prototype hardware is currently installed in projects at three independent shops.
nissan leaf motor to miata manual transmission adapter
Precision adapter plate mating the Nissan Leaf EM57 motor to Mazda Miata NA/NB 5-speed and 6-speed manual transmissions. Engineered for correct alignment, bolt pattern, and clearance — no fabrication or guesswork required on install.
Adjustable mounts designed specifically for the Nissan Leaf motor, allowing fine-tuned positioning for proper drivetrain alignment and clearance across different chassis applications.

Miata Transmission Mount
A matching transmission mount engineered to pair with the adapter plate and motor mounts, completing a properly aligned, vibration-controlled drivetrain install.
PROVING GROUNDS
Our primary R&D platform is a full EV conversion of a 1991 Toyota pickup — the proving ground for the parts that will eventually become a complete conversion kit for the 1985–1994 Toyota pickup platform. This is a deliberate, engineering-first approach: get the truck right, then package what we learn into a kit other people can install with confidence.
