the 2L in the scorpio is slightly less powerful than the one in the RS2000 i think there might be a difference in the cams aswell as the inlet and exhaust manifolds, the oil dipstick is probably also in a different location for the rwd, as for the 2.3 in the galaxy or scorpio that produces lots more torque than the 2L and a 2.3 galaxy or scorpio using the RS2000 inlet and exhaust and cams with slightly skimmed head to raise the compression ration can see about over 170 in bhp and torque, as for turbo charging it can be done there was a guy that built a 2.3 RS2000 turbo and that made 300bhp at 12psi, also the standard RS2000 engine could probably be used to give 200bhp with standard internals and a low pressure turbo
