Engine data

Hi guys, for the 3D-CAD drawing i need to make i need some engine data... The engine of the choice was the C5's 1.8 16V,as found in my dads car. So far i have sent close to 50 emails. I phoned a dozen of companies/importers and visited 5 dealerships... I even called to Citroen HQ in France. They were quite unwilling to help. I do get some pictures of the engine in my mailbox, but not with the exact data i need. I dont think anyone of you might be of help,but I can try atleast The data I need: - length,width and heigth of the connecting rod. - The diameters of the big-end and the small-end - Used material in the pistons,cilinder,connecting rod and the crankshaft. - The shape of the piston. Is it flat on the top ? What is the diameter deviation (when cold) between the top and bottom of the piston ? - Any other information about the engine components you might find useful. PS: If i suddenly get into a coma or something,you know i have received the phone bill
