    im doing a build in my integra, i have the b18c1 block, its got alot of miles on it so i am honing it out a bit, the pistons i bought are .20 over stock size so do i bore the block out to 81.25? or will the .05 leave to small or to large of a gap?

    i was told that you dont want the pistons in there to tight cause you will fry the rings
    but if the pistons are .20 larger then stock then i want to bore it out to .20 exactly?

    so for the tighter the piston to wall is the safer... i didnt know if you wanted a little room or snug to where it may want to grind..

    stock bore on my block is 81mm i bought pistons that are 81.20 so i want to bore the block to 81.2008 to keep a safe number.
    just making sure sorry to repost
    so that would be the proper ring clearance?

    What is the standard for cunt hair thickness? Just wondering... :ph34r:

    But yeah, take the pistons, block, and specs to the machine shop, and come back for them in a few days.
