The S42 engine was a 2.0L touring car engine with a 86.5mm bore and around a 85mm stroke, which shared the same block as the street going M42. Unlike the common M42, the S42 had a more sophisticated engine management system, and had individual throttle bodies. The S42 unfortunately did not share the same valvetrain as the M42, and is a solid lifter valvetrain (possibily from the S50Euro) fully capable of over 9000rpm, but was limited to a 8500rpm redline, as dictated by touring car rules. It was mounted upright in the bay, not slanted, and ran on a full dry sump oiling system. The pistons had a static compression ratio of around 12:1, and running on pump gas, the S42 made around 280hp (and up to around 310hp later in it's life).
