This is a good point, if in fact the Z's chain is the same. Two of the more well documented cases, yours 1.8t and welcome2try, had variables other than just more power that may have contributed. I believe yours was a possible manufacturing defect in the chain itself, correct? Welcome2try's breakage was due to faulty/incorrect parts in the valvetrain from improper install. His was also and '05. I had heard that the '07? chain was slightly stronger. Can anyone confirm that? I don't believe an UD pulley is the cause however I feel it's more than just simply more power or else I think there would be a lot more stories like these. That being said it's silly not to upgrade the chain when doing a cam swap. Have there been occurances of the aftermarket chains breaking? If so does anyone know the cause in those cases?

I was also under the impression that there is no master link, but for some reason this link is a significantly darker color than the rest. This lead me to believe that it was a "master" link somehow. If not, then maybe the stress of bending changed the color or it was always a different color? Maybe it was a defective part?
