I keep drooling over those pistons you have created Edinir! The temptation is too much... must....order... PISTONS!!! Arghhh! :bdaypresent:Agreed about a quick finish. When you put the turbo water pump on I think it has 6 or 7 bolts and all seem to be different. Obviously the water pump bolt committee was in a hurry for production. The new pistons just represent the latest thinking on pistons in 2017 and I am hopeful that they are an improvement.
