=Introduction= Turbochargers have been installed on production cars for many years. Similar turbos are regularly sourced by different OEMs from the same suppliers and fitted to models. This make interchanging or upgrading between vehicles possible, however information on what turbo is fitted to particular cars and what fittings and specification they have can make such exchanges a difficult and bitter experience for the amateur. This wiki attempts to gather all the information necessary about turbochargers to assist in the process of maintenance, repair or upgrade for the amateur. Another point of note is that the same car in different markets may have differing turbochargers fitted. For example, Japanese domestic market (JDM) Nissan 200sx came with a Garrett Ball Bearing GT28, while many export models had only Journal bearing variants.
