i picked up an 02 RX DI for cheap with a blown motor. the previous owner tried to repair the cylinders and wound up over boring them beyond the point of getting an available oversized piston. I cant decide if i should do the SBT cylinder exchange for $500 or get new sleeves and have them installed and bored. Does anybody know how much it costs to have the cylinder sleeves installed and bored? or is it worth it to just buy the whole new cylinder. Thanks.
