valves and camshafts
Being more used to older BMW's i am finding sud ownership full of undocumented variations when it comes to nearly every part of this car. worst of all seems to be all the engine variations.
So far i have surmised the folllowing: but i am not sure if i am correct, would be grat to have this level of spec per engine code.
36mm 1.3/1.35 ?
40mm 1.5 105hp & 1.7 mech
exhaust valves seem to mostly be 33mm
what i would really like to know is what are the standard valve lift/clearances (max and TDC) for single and dual lobe cam. I would like to deck my head to increase the comp ratio, but at the same time ensure i can upgrade to highlift cams without removing the bottom end again to have to machine valve pockets in the pistons.
can anyone verify any of the above or have any info on sud camshafts?
