to the exhaust. This enabled the use of various octane fuels and also made the use of the turbocharger safer for the engine. Some 900 Aeros, Carlssons and Commemorative Editions had special APC controllers in red and black enclosures (so-called "redbox" APCs) that provided more boost and increased power to or without a catalytic converter. By 1983, Saab had sold 100,000 turbo-charged cars and were leading the world. At first, Saab used a Garrett turbocharger (T3), which was oil-cooled. From 1988 through 1990, water-cooled T3s were fitted. In 1990, Saab fitted Mitsubishi TE-05 turbochargers in the SPG models only for the USA; for other countries, and for the US from 1991, all 900 Turbos were fitted with the TE-05. Also water-cooled, the TE-05 was slightly smaller than the Garrett T3s, providing improved throttle response and quicker spool-up. The TE-05's exhaust inlet flange utilizes a Garrett T3 pattern.
