Do you need new pistons after boring?

If you over bore the cylinder, you must use a new piston. When clearances of the piston to wall are measured in the thousandths of an inch (or sub-millimeter) and you bore the cylinder +. 010″ over (or +. 030″ or whatever), there is too much gap for the old piston to take up the slack.

Does boring an engine increase displacement?

There are only two ways to increase an engine’s displacement: You can bore it (engine boring increases the cylinder diameters) or you can stroke it (engine stroking increases the crankshaft stroke).

Can you reuse old pistons?

The use of reused pistons can reduce the cost of an engine overhaul rebuild. In a rebuild kit, the pistons are usually the most expensive part. It is possible to make the kit affordable for nearly everyone by taking them out.
