I have a set of used wiseco pistons #6554M795 1.6L bore is 79.5mm and compression ratio of 8.5:1. These pistons were in my car for only about a 1000 miles. As you can see there was some detonation and one of the pistons got destroyed. I believe the other three are salvageable, but I am not 100%. These parts are an older design and have been sitting in a closet for a long time.I just wanted to offer them up to someone that could possible use them but if no one is interested they will end up in the scrap yard. I'm asking $50 shipped in continental US. Feel free to ask any questions.
