I'm curious. What percentage of these Porsche engine failures had after market modifications?

I'm not putting blame on the after market mods in anyway. I'm asking out of lack of knowledge/experience. I'm sure someone here with more knowledge than me can weigh in on the subject of aftermarket mods vs. long term reliability.

Porsche engine reliability was compared to that of Camrys earlier in this thread. I'd hazard a guess there are more modified Porsches on the road than modified Camrys.
