The engines were given numbers, for instance B201 is a 2.0-litre (20) engine with one camshaft.
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
Valmet Automotive in Uusikaupunki also planned a downsized 1.6 liter version of B201, to better suit Finnish vehicle tax laws. Downsizing was made by using a narrower cylinder bore. The prototype engine produced 92 PS (68 kW; 91 hp) at 5400 rpm, fitted with Bosch K-Jetronic fuel injection. One such prototype engine is displayed in the Uusikaupunki Saab museum.
B202 and B212
In 1984, Saab added a 16
In 1991, Saab introduced a 140 bhp (104 kW) 2.1-litre
Engine builder John Nicholson also developed a Formula Three engine from the B202, for use in a Reynard 853 chassis.[1] This version one of the first to use Saab's direct ignition system (SDI) and produced 165 PS (121 kW) at 5600 rpm. Its other strength was high power in an unusually broad powerband for a naturally aspirated racing engine.[1]
B204 and B234
A major redesign of the H engine came in 1990 in the form of the new B234 for the Saab 9000. The B234 featured an increase in stroke from 78 mm (3.07 in) to 90 mm (3.54 in), increasing the displacement to 2.3 liters. With this increased stroke also came a new engine block with increased deck height to make sufficient room for the increased stroke length without being forced to use shorter connecting rods, and in-block counter-rotating balance shafts for reduced vibration (NVH). There are two generations of B234 engine, one made from 1990-1993, the other from 1994 to 1998. The later motors had a revised oil sump system, head, timing cover, and different bell housing pattern. Unlike the previous B202, the block was no longer angled, but straight, something that made it unsuitable for the 900 model with its gearbox under the engine, built into the engine oil sump. The longer stroke B234 was last produced in 1998, that being the last year for the 9000 model. The B234 was selected as one of Ward's 10 Best Engines for 1995 and 1996.
The B202 was still being produced in 1993, but for the new generation Saab 900 being released in 1994 a new 2.0L engine was required. This new engine, the B204, was based on the 9000's B234, but in order to make the engine fit in the 900 the engine had to be shortened. This meant that a new chain drive for the camshafts was required to reduce the length of the engine. The B204 engine was available with natural aspiration in 900, 9000 and 9-3 in the form of 2.0i (B204i), with a low pressure turbo in the form of 9000 and 9-3 2.0t (B204E) or Saab 900 and 9-3 2.0T (B204L). B204R was briefly available in the 1999 9-3 Aero (U.S. market 'SE') model. B204 was in production in the Saab 9-3 until 2000, when it was replaced by B205.
With the introduction of the
Turbocharged engines used Garrett T25 turbochargers and the B234R (9000 Aero manual) used a Mitsubishi Heavy Industries TD04HL-15G-6 in model year -93 and TD04HL-15T-6 later on.
The B204 and B234 are regarded by engine tuners as the preferable engine for performance tuning over the later B205 and B235 engines as the internals are of a higher strength. The later models had lightened internal components to improve efficiency and fuel economy but limit the total power output when the engine's software is revised to increase the boost pressures and specific power output. The B204 engine became a very popular engine swap for Vauxhall and Opel Astra, Calibra, Cavalier and Vectras with the GM T-body platform, in Scandinavia in the mid 2000s—the engine uses the same mounting positions due to sharing the same platform. In the UK it is swapped into rotary equipped Mazda RX8, in Ukraine and Russia it is a swap option for Daewoo (now Chevrolet) models of similar age.

Note: The primary difference between the B204L and the B204R is with the
B206
The B206 is a version of the B204 but without the dual balance shafts. It was only offered as a naturally aspirated engine B206I producing 133 hp (99 kW), seemingly a Europe-only option in 1994 non-turbo 900 NGs. This engine is popular among Saab tuners in Sweden (e.g. Trollspeed) due to the lack of balance shafts but with presumably equal strength as the turbo blocks with balance shafts.
B205 and B235
The B205 and B235 engines are an evolution of the B204 and B234 engines. They were introduced in the 1998 Saab 9-5 giving reduced fuel consumption and emissions with improved refinement. The changes included lightweight internal components:lighter valves, softer valve springs, lighter pistons, and lower-drag oil pump. Another development was the introduction of the Trionic 7 torque demand type engine management system. Trionic 7 equipped engines have the black direct ignition casing on top of the engine rather than the red of the Trionic 5.
BAIC
The BAIC BJ40L is available with a 201 hp (150 kW) engine named B201R and a 231 hp (172 kW) engine named B231R.[4] A 177 hp (132 kW) engine named B205EFA is offered in the Senova X65.[5] The BAIC BJ80 is also available with the 231 hp (172 kW) B231R engine variant. The B201R and B231R models do not use Saab's Trionic engine management system and direct ignition cassette.
