oversize (plural oversizes)

1. (automotive) The increased size of the bore of an engine when it is rebored.
   • 2005, Daniel Stapleton, How to Plan and Build a Fast Road Car, page 14:

     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.

   • 2006, Rod Grainger, Pete Shoemark, Mazda MX-5 Miata 1.8 1993 to 1999: Enthuasiast Workshop Manual:

     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.
