[QUOTE="texas_snake, post: 16510766, member: 11539"] So I am checking into a teksid build with a 2618 alloy piston. This will be a .020" over build as it will have off the shelf parts. Looking for advice on piston to wall gap considering expansion of 2618 alloy with up to 14lbs of boost. I want to give my machine shop the correct final bore size for this plan. Details: Teksid aluminum block (97 98) with torque plate hone 2618 alloy piston with side coating Advertised piston size: 3.572 Raw piston size: 3.5685 (offering .0035" P to Wall gap) Manufacture advises a bit more room with the boost goals to be set at .004". So final size would be: 3.5725 (by this advice) I am also trying to avoid cold piston slap. Manufactured stated .004" will be good for extra room for heat and should not be noisy. Others running this gap with an aluminum block and 2618 piston? Thanks [/QUOTE]
