GReddy exclusively uses GReddy Spec. Mitsubishi Heavy Industries, Japan Turbochargers, many of which are unique to us, including the popular 18G’s, compact TZ line and large hybrid T-power Turbos. It is well known, Mitsubishi turbochargers are among the highest quality turbos in the industry today. They utilize a durable center cartage, an extra large free-floating bushing with a large diameter center shaft. We believe this design to be superior to all other standard bushing turbos as well as many ball bearing types.
