Porsche 911 RSR 4.0 Liter Twin Plug  MFI Engine

  Spotted in Bochum, Germany is a Porsche 911 RSR 4.0 Liter Twin Plug MFI Engine for $53,350 USD.    This engine is based on the FIA international sports law for group 5 and built on an original 3,0l engine case, but increased to 4,0l displacement.  The displacement is exactly 4000 cm³. The torque is 415 Nm and the power output 390 hp at 6900 rpm.  The maximum allowed rpm is 7000. The set up is dedicated for rallye and street use with the target of a broad and constant torque range, even at lowest rpm’s. So already from 3000 rpm, it provides more than 350 Nm with a smooth and flat torque range up to the maximum of 7000 rpm.  It is equipped with Bosch mechanical fuel injection (MFI), authentic Bosch design twin plug ignition and RSR exhaust system from stainless steel.   Does anyone else have a comparable engine for sale?
