JDM Motors For Sale

Japanese Domestic Market motors, or JDM engines, differ greatly from the components and engines we’ll see for cars sold in the U.S. Even though the brand names are the same, such as Honda, Nissan and Toyota, there are significant differences between a Honda sold in the U.S. and a JDM Honda engine or a JDM Nissan and a Nissan sold in the U.S.  There are couple different reasons why JDM engines are different from U.S. engines – most of which have to do with differences between Japan and the U.S.

At, our JDM specialists know which JDM motors will be an improvement on the original equipment manufacturer (OEM) parts and which makes and models can take a JDM engine. Through our industry connections with major importers and aftermarket dealers, we either have the JDM engine you need in stock or we can find it. Have a question about upgrading your car with a JDM engine? Just call – advice is free.

JDM engines are built to be sold in Japan. Because of this, they adhere to different emissions and regulatory standards. For instance, Japan has signed and ratified the Kyoto Protocol and thus manufactures products to reduce carbon emissions and greenhouse gases. The U.S., meanwhile, is a signatory to the Kyoto Protocol but has not ratified it and is thus not held to these standards. JDM engines are built to adhere to Japanese emissions standards.

JDM vehicles often also have stiffer suspensions and improved throttle response. This is due to Japan’s relatively shorter, winding roads which demand better handling. In the U.S., however, much of the driving is long, highway driving, thus a smoother ride is preferable. Because of this, a JDM engine may be more optimal for high performance driving than a U.S. marketed vehicle. 

Japanese manufactured engines made for U.S. markets are also oftentimes built with less features in order to bring costs down. For example, the JDM version of the Nissan GT-R has a built-in GPS that detects when a car is on a Japanese racetrack that automatically disables the sped limiter feature. It is believed that this function is not available for U.S. Nissan GT-R’s, and thus overriding the speed limiter must be done manually.
