Ryans gona jump me but Im gona say it anyway.
Doesnt mean jack! Look at Mk3 XR2i's, early ones had the same 8v CVH as the Mk2 XR2s but Ford replaced the Carb with EFi 110bhp outa Dagenham or somewhere, later they changed the 8v CVH for the first of the 16v Zetec engines and up'd the cc from 1600 up to 1800 and also threw in another cam.
1800 Twin Cam 16v you'd think thata destroy a 8v CVH . . . Wrong the Zetec put out a amzaing 110bhp
Only the later XR3i's and the RS1800 with different throttle bodies and few other minor changes made 130bhp and that was on the optomistic side.
So it is possible to change things and not make extra bhp, besides if they had made a more powerfull model dont you think they would have shooted about it and asked for more money
VTS_16v_Boy ducks for cover incase itsafastworld turns up and bets him with a large stick for mentioning Fords on a Saxo Forum
