    If you are using stock-sized pistons, and lumaki na ang butas ng cylinders, a sleeve will work.

    But sometimes you have to overbore to insert the correct sleeve so pareho mo din gagawin. hehehe.

    Kapag rebore, you will be using larger pistons. Dapat take into consideration mo ang wall thickness. Baka masyado na maging manipis after boring.

    For what car?

    For American and Euro cars, Mahle pistons and Federal Mogul are the norm.
    For high performance, Mahle forged pistons and JE Forged Pistons are ok.

    paparebore mo din yata iyan kasi hindi naman perfect ang naging circumference non para ipasok ang tamang size ng sleeve

    kung naturally aspirated lang to and you're not planning to go custom force induction.Boring and honing will be fine.Depende kung anong material ng sleeve ang gagamitin.Kung boring and honing magpapalit ka rin ng oversize piston.

    IMO it's best that your trusted machinist to decide since it's all factors of measurements and economics

    for me ha, unless, may senti-value makina mo, mas mapapamura kung palitan mo nalng ng surplus kaysa sa parebore/sleeve. mas feasible pa mah 4g63/67/92/93 ka kaysa keep mo stock engine mo at i-prep mo for performance...

    magkano lang "change-engine" sa LTO? makina at labor lang katapat nyan....

    opinion ko lang po to,ha....
