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....
