JDM Engines & Parts in Phoenix, Arizona

Top Tier Japan is America's leading importer of JDM engines and auto parts, based right here in Phoenix, Arizona. Through our parent and sister companies we've been in this business for over 20 years — supplying quality Japanese engines, transmissions, and parts at competitive prices, backed by a real warranty. We sell Japanese engines for all makes — Toyota, Lexus, Honda, Acura, Nissan, Infiniti, Subaru, Mazda, and Mitsubishi. Whether you need a replacement engine for your daily driver or a low-mileage automatic or CVT transmission, our Phoenix warehouse stocks engines and transmissions pulled from Japanese donor vehicles — typically in the 50K-mile range, far fewer miles than comparable US cars. Every unit is compression-tested and inspected before it ships or gets picked up, so you know exactly what you're installing. We keep it simple: quality over quantity, and unbeatable customer service. Serving Phoenix and the greater Arizona area, with nationwide shipping on every order.
