    • LOW MILEAGE

      We hand-pick our JDM motors and transmissions with an average of 45,000-65,000 miles. Japan's strict emission laws make it costly to keep cars there, so many are sent to junkyards or auctioned off. We import them straight to our NJ warehouse.

    • AFFORDABLE PRICE

      We compare our prices to our competitors' to make sure you get the best value. We also consider any other costs when replacing an engine, like labor and parts, to make sure our prices are fair. Check out our products and see why ours are so cost-effective.

    • HUGE SELECTION

      Get your JDM motor with ease! Just make sure to research the vehicle carefully to ensure you get the right motor. When looking through our selection, take note of the year, make, model and displacement of your car. It's a match? Then we'll sell to you!
