Say I was to overbore a B18B1 or B18C1 is there a formula to figure out how many more cc's I acquired from boreing the cylinder .040 over. Whether you can actually bore one or both of these motors this much I'm curious. I believe reading in one of my honda books that the LS swap is worth 60 something cc's and while this isnt much to show a power difference I know it affects the powerband itself much more. If someone could enlightenment more on this it'd be apreciated.

 

1/2 bore x 1/2 bore x 3.1416 x stroke x number of cylinders equals displacement.Keep it all in inches or mm. 1 mm equals .039". One mm overbore is it on stock Honda sleeves.
