How does the South African-spec S50 B32 engine differ from that of the European-spec version?

Due to low-octane fuel requirements, the S50 B32 motors produced for South Africa utilize different pistons which result in a reduced compression ratio of 10.5:1. These engines produce 310 hp (DIN) at 7,400 rpm and 251 lb/ft of torque at 3,250 rpm. More.
