"[edit] S50B30US
The S50B30US was a 3.0 L version, which powered the US-spec E36 M3. Power was 240 hp (179 kW). Unlike the RoW S50, this engine used a regular M50 intake in lieu of the individual throttle body set up and hydraulic valve lifters in lieu of solid ones. The cylinder head and the VANOS system are also different on the US S50 versus the RoW model; again having more in common with the regular M50 than the Euro S50.
Applications:
1995 E36 M3
[edit] S50B30
The S50B30 was a special sports-oriented 3.0 L version, which powered the RoW spec E36 M3. Power is 286 hp (210 kW). The S50B30 has a bore of 86mm and a stroke of 85.8mm, with a total displacement of 2990cc. The engine has a maximum permissible speed of 7280rpm +/-80, and a permissible constant speed of 7000rpm. It used an ITB intake system with an oversized MAF and a tubular exhaust manifold. The cylinder head was unique and the VANOS system was more advanced than the one used on normal M50s.
Applications:
1992-1995 E36 M3
[edit] S50B32
The S50B32 was an evolution version of the S50B30. Power of the 3.2 L version is 321 hp. This engine has a bore of 86.4 mm and a stroke of 91.0 mm giving a displacement of 3201 cc. It has a maximum permissible speed of 7600 +/-50 rpm, and a permissible constant speed of 7400 rpm.
The US counterpart, the S52B32, shared some of the European versions' internal dimensions but was festooned with the restrictive M52B28 intake manifold and used a cylinder head design more akin to the M52 than to its fire-breathing European cousin. Power for the S52B32 was only 240 hp and maximum permissible engine speed was in the 6500 rpm range since it used hydraulic lifters instead of solid ones.
Applications:
1996-1999 E36 M3
1997-2000 M Roadster
1998-2000 M Coupe "
