Crankshaft grinding 350Z Technical 350Z 370Z UK
May 30, 2017· Cant say i have seen anything about the VQ crank being specially coated, it could be Nitrided but most forms wont preclude grinding, yes a decent engineering company that is used to crank grinding will grind the journal to the tolerances for the manufactured oversize bearing, which means it will fit and have the correct crush tolerance when fitted without ever having to use plastiguage or similar.
