    i hear from some big places that you don't have to sleeve a block if you go all motor. some shops also say it's better to do it. i am confused on what really is the best for me.what is the largest bore on stock sleeves. b18c looking to run 11.5.1 or 11.8.1 cr. not sure if i should bore to 81.5 0r bigger like 84mm/85mm. any help?

    If you want adding strength you should definitely sleeve your motor, but it costs $$$. If you want a cheaper check into block posting, its a reallly interesting solution; some people don't like it though because you are drilling into your block.

    81.5 is the stock overbore, and doesn't require sleeving.

    82+ will, as there's just not enough material to shave off.
