Engine Designations
Not all engines are available in all markets. For example, smaller engines tend not to be available in the US. Diesel engines were not available in the UK until fairly recently. Power figures are for european models, most older US engines tend to be restricted by emissions regulations.
Engines are designated in the format M10B20, which is the 2.0 version of the M10.
S implies a Motorsport engine for an //M car, such as S14B23 for the E30 M3 2.3's engine.
BMW changed the M in favour of N for engines developed after about 2001, so we now have N52B30. N engines tend to be Valvetronic unless they're turbocharged.

The "little six", called M60 initially.Early 2.3 in E21 323i was Jetronic-K, E30 323i was Jetronic-L. Later E30 323i's have 10bhp more.
Eta is lower rpm fuel saver. Can be identified bt longer intake manifold runners, has fewer camshaft bearings.

VANOS = variable valve timing.
To convert from ft/lb to Nm multiply by 1.36 (100ft/lb = 136Nm).
To convert from BHP to kW multiply by 0.735 (100 bhp = 73.35kW).
Engine weights are for a dry engine with no manifolds, starter motor, alternator, etc. They will vary by 2 or 3 kg for different types of fuel injection and model year. US M50 had an iron block due to sulphur problems and is much heavier than euro. Anti-pollution kit will add a few kgs to earlier US spec engines. Where you see (short) this means the weight is for a short engine with no heads or ancillaries.
