noun

1. (automotive) The increased size of the bore of an engine when it is rebored.
   However, any increase in capacity is useful and, if an engine is worn and needs a rebore, it's worth considering boring to a near maximum size rather than simply having it bored to the next oversize. 2005, Daniel Stapleton, How to Plan and Build a Fast Road Car, page 14
   Have your local machine shop rebore the cylinders to the next nearest oversize and supply new pistons and rings to suit. Recommended rebore oversizes go up in increments of 0.25mm/0.010 inch. If the engine's already been rebored, you'll usually be able to find the oversize stamped in the piston crowns. 2006, Rod Grainger, Pete Shoemark, Mazda MX-5 Miata 1.8 1993 to 1999: Enthuasiast Workshop Manual
