In a JDM engine swap, high-powered engines from Japan are installed on your car to replace the stock engine. These engines are usually made by motor companies like Honda, Nissan, Toyota, Subaru, and Mitsubishi. The reasons this type of JDM engines are so popular are: very low miles, straight from Japan and these engines come from cars that have been well taken care of due to strict laws on vehicle inspection (Shaken) in that country. They are thus fairly used in the UK and quite beneficial to a performance enhancement.
