Sorry guys, but I did a search and I couldn't find what I was looking for. It's kinda sorry since I was an Endyn dealer for two years, but I forgot what the pistons dome cc displacement was for the 81.5mm turbo/low compression piston. I remember the high dome all motor pistons were +7.45cc, and I know the dished ones are negative, but I forget what number. Any help would be appreciated.
