For almost $13,000, you can own this engine. The catch is that it's in Germany. No affiliation. Just spotted it.
270 BHP @ 8700 RPM
197 lb-ft torque @ 6360 RPM
86.42mm bore x 91mm stroke
Pauter rods, Wiseco pistons
TRW 35mm intake, 32mm exhaust valves
STW cams intake: 304*, exhaust 312*

AFAIK, the real S42 only has an 86mm bore x 85mm stroke. The valve cover is also CF on the real S42. The real S42 also doesn't use Pauter rods and Wiseco pistons.
