increasing the bore really doesnt help the displacement that much. they have a bore chart at this site breaking down each stroke, and how many cc's youll pick up by running a larger bore.
to get a truely positive increasement in displacement you should look at restroking it.

no im not wrong. what i said was in order to really pick up more displacement it is better to change the stroke.
a gsr that is bored to 84.5mm does not make it over 2 liters. read the chart this website has so graciously provided. at 85.5mm a gsr engine becomes a 2 liter.
calesta, what engine do you have? has that engine been resleeved? if you have a b-series that would mean your bore would have to be 87mm, and only the b20 will truely give you 300cc's more.

piston to deck height is not 0 on b series blocks last i checked. they fall slightly short, or i have drank too many 24 ozers. they leave bout 3mm (?) of combustion.
