The biggest difference is the camshaft, though there are many details to consider, for example the metering unit calibration, throttle bodies/linkage, overdrive...
But the real question is why do it? In reality the CP series cars never made 150bhp, and performance difference vs the CR cars is marginal.
Merely the opinion of CP series owner!
