hi can any body please tell me the differences between the williams engine and the megane f7r iv been told the megane has smaller ports and bigger valves {33mm] iv also seen power figures quoted of 138 140 and 150 for the megane. id like to know as i just ordered a megane engine for my r5 and im hoping i havent made a mistake

hi mate..

megane bottom end is for all purpose's identical to the william's.

head has smaller better ports and 33mm inlets slightly milder cams but makes 150bhp ....

only issues with a 5 install are lack of dizzy really as it runs coilpacks..

willy head has 32mm inlets slightly wilder cam's has a dizzy

brilliant thanks for that buddy thats exactly what i wanted to hear the dizzy is no porblem as im using mega squirt and ford coil packs for itbs. one other thing i was wondering is, i have fast road cams in a 1.8 16v can they be made to fit?
