The pulse width of stock injectors is the real culprit imo and from who I've talked to and what I've read. The problem is: stock injectors are too small to spray fuel in the optimal window (time frame) so you end up chasing the piston with fuel shot (think blow torch) piston gets too hot and weak to handle the cylinder pressure. Crack starts and forms a hole or cracks completely across and thru, thus losing compression to the crankcase.
