Excerpt: Alfa Romeo's in-house V6 engine design made its initial début in 1979 in the Alfa 6. Introduced in 2.5 L guise, production engines would eventually range from 2.0 L to 3.2 L displacement. With modifications it is possible to increase engine displacement to 3.8 L (~232 cu in). Initially developed in the early 1970s by Giuseppe Busso, the original SOHC 12-valve design employed short push-rods to operate the exhaust valves in a design similar to that of earlier BMW / Bristol engines. In 1993, the first DOHC version of this engine appeared powering the Alfa Romeo 164. The Alfa Romeo V6 has been also quite popular in "kit car" type vehicles like the Ultima GTR, , Hawk HF Series and DAX. and is also used in the Gillet Vertigo sports car. A 2.0 L (1,997 cc (121.9 cu in)) version was introduced in 1983. Both carburettor 132 PS (97 kW; 130 hp) and fuel injected versions were available from the start. A 2.0 turbocharged version, derived from the 3.0 L 12v, was introduced in 1991 in the Alfa Romeo 164 with 210 PS (154 kW; 207 hp). Applications: The 2.5L as longitudinal installation in GTV6. The original engine displaced 2.5 L (2,492 cc (152.1 cu in)) and produced 158 PS (116 kW; 156 hp). It was a 2-valve per cylinder design with a single belt-driven camshaft per cylinder bank and six carburettors fitted. Fuel injection was added for the 1983 Alfa 6, which produced the same 158 PS (116 kW; 156 hp). The 2-valve engine ended its life in the Alfa 155, where there were two series for this engine, the 2.5 L developing 166 PS (122 kW; 164 hp). Differences between them were small and only on torque and power delivery producing the exact same horsepower. Applications: 2.5L V6 24V from Alfa Romeo 156.A four-valve version was introduced in 1997 wit. More:
