B201
B201 is the original H engine with two valves per cylinder and a single overhead camshaft. It was introduced in 1981 and unlike the B engine it did not have the central shaft which used to power the distributor, oil- and coolant pump. Instead the distributor is located at the front of the cylinder head and directly driven by the camshaft, while the integrated waterpump was replaced with a separate unit to the rear of the engine.
It was available with 100 PS (74 kW; 99 hp) at 5200 rpm using a single carburettor, 108 PS (79 kW; 107 hp) at 5200 rpm using a dual carburettor, 118 PS (87 kW; 116 hp) at 5500 rpm using Bosch K-Jetronic fuel injection and a turbocharged, fuel injected version with 145 PS (107 kW; 143 hp) at 5000 rpm. In 1986 an intercooled version of the turbo engine also became available, it produced 155 PS (114 kW; 153 hp) at 5500 rpm.
Valmet Automotive in Uusikaupunki planned also a downsized 1.6 liter version of B201 mainly due Finnish vehicle tax laws. Downsizing was made just with smaller cylinder bore. Prototype produced 92 hp at 5400 rpm with Bosch K-jetronic fuel injection. One prototype engine is displayed in Uusikaupunki Saab-museum.
