Sleave it and you can get up to 86mm.

Re: bore (B18C-EJ1)

well thats not technicly a sleeve on the bottom a sleeve is welded in place, like the one on top that is a want to be sleeve (block Guard) not weled in. Not to mention those things suck for all motor setups. I would sleeve it and bore it to 85.4 with aftermarket sleeves or 81.4 with the stock honda sleeves.
