The Alfa turbo engine, the 890T, was not reliable. Chargers blew off regularly and power output had to be reduced down to the level of the non-turbo cars just to achieve the necessary reliability. On more than one occasion, Osella tried to replace the 890T with more up-to-date Motori Moderni turbos (which Minardi did not support) or with Cosworth engines. In the end, both were too expensive, so Osella had to stick with the increasingly outdated but cheap 890T.
