The DC2R B18C engine does not take much to weaken the block strength if you bore it out too much. Get the block inspected to see how much the bad bore needs to be machined and get all of the bores machined to that size. 40 thou is about the limit from memory without fitting a set of sleeves(expensive option) |

If you change the bore size you will need to get a head gasket and pistons to suit. It's not worth boring to the point that you need sleaves if you arent going to do further work to the engine imo. A B20 conversion is definately the more cost effective solution as iamhappy26 said if it leads down that path. If you are planning on boring it out, talk to the guys at Toda if you're after a larger diameter metal head gasket. |

Big issue with boring engines is clearance - dont want to weaken the metal between cylinders, or between the cylinders and water galleries etc. You can bore them out then have the cylinders sleeved with a tougher material but is expensive. |
