Not even close!
Honda recommends as a MAXIMUM to bore 20 over or 0.020 over (same thing). This will give you a bore size of 81.5mm. This is only for purposes of repair on the cylinder wall, NOT for any performance gain.
If you want/need to go any more, you will need to get aftermarket ductile iron sleeves. In that case, most will allow you to go to 84mm as a maximum on a B18 block.
