Sorry mate, no it doesn't. Internal engine detail defferences are too many to mention on here, lightweight Penkl rods for a start. The difference between the SPS engine and the pukka CORSA was that the SPS engine was detuned by fitting a 91 spec CORSA zorst cam and a different airbox.
There were a few so called SPS's knocking about very early on that were SP4'z that were tarted up by addition of some hotter cams, but they were definately NOT true SPS/SP4S's.
The SP5 had the same engine as the SPS supposedly. Funny how the SP5 made about 10 horse less though.
