if i waa going to then the first thing id be buying the cosworth workshop manual

this will tell you everything you need to know, fromstrip and rebuild to take out and fit

gives you all the toque settings, tolerences etc aswell

even tells you have to strip the gearboxes and rebuild them,almost everything in there to give a cossie a good overhaul



and if your still not confident at doing it after reading the manual then just do what i did and let someone else build the engine
