[streetspeed607]

whats the maximum bore i can go with stock seleves on my f22a(its going in a civic with with a h22) goin all motor here

[uslspct]

F22a, like +0.5mm. 1mm if you're feeling lucky. But I don't understand the civic H22 part.

put in darton MID's 87mm's!!!! and yes you can do 87mm sleeves

He's asking about stock sleeves. I'm not completely positiv but I want to say I've seen one 1mm over. I know there are pistons available for this bore but that doesn't mean that they're for facotry sleeves. If you do decide to go that far, don't boost.

ihave done 1mm over with forged pistons and i still had a good amount of steel left in the stock a sleeves...my .02

[accrdpower]

i'd say for safety's sake and durability just to drop in some darton sleeves....u can go from stock 85 to 87 with no worries

I would not do anything over 86mm (1mm overbore) on a F22ax if you want to retain stock sleeves. If you want 87mm, get a H22 or H23 block is cheapest. However, if you must get 87mm on a F22ax, then pay for the sleeving, it is expensive...like $800+
