Motori Moderni
With being the final year for the turbos in Formula One (until ), Motori Moderni pulled out of the sport at the end of 1987 rather than try to adapt the engine for an even lower pop-off valve limit of 2.5 bar and a lower fuel limit of just 150 litres. As a result Minardi were forced to use the Cosworth DFZ engine in 1988.
