to house the pistons
An engine block is usually cast iron or aluminium.
When you say cylinder, you're talking about the space where the piston is. The cylinder is but one of four or six or eight in an engine block. You can't change one cylinder as it is part of the block. You would have to change the entire block or bore each cylinder to specifications equal to each for the engine to run proficiently.
You can "Magnaflux" the block assuming the block is cast iron or steel and the block is stripped down and cleaned for rebuilding.
