While 2.0-liter versions of the Biturbo were reserved for the Italian market, a 2.5-liter version developed for export was presented in 1983. The three-valve-per-cylinder V6 engine had an increased bore to expand its capacity to 2,491cc. Cylinder liners of cast iron replaced aluminum, and this engine did not rely on intercoolers for the two IHI turbochargers. The Biturbo 2500 maintained the Torsen limited-slip differential from the previous models (a world-first on a production car), while a more powerful version was named Biturbo ES. In 1987, the Biturbo 2500 and Biturbo ES adopted fuel injection and the name was changed to Biturbo Si 2500.
