I don't have any pics of it, but I once blew a chunk of piston out. It was the ring land on the side, and it was gone half way around the piston. Weird part was, I don't know how the pieces got out, there was no damage to the sidewalls of the cylinder, but the head was chewed up. This happened on a 1985 300zx turbo. It was my fault as at the time I didn't know enough about cars to know not to turn up the boost without supporting mods.
