having a little dilema so to speak of.
basically it's not an rs, but couldn't think of which section to put this in so here goes.
i'm about to order my rods/pistons and bearings from the states and if i go for standard bore of 85mm the items will be shipped this week, if i go for the oversized ones then it'll be 5-6 weeks.
then there is the boring of the block which is only a couple of days turn around, extra cost is only about £100 for the extra capacity.

i'm just after someone saying what is the better option as i've heard that the zetec cylinder walls are already thin without the boring, i'm happy to wait if there is a genuine advantage i'd kick myself over at a later date.

cheers

p.s. put on focus section, but probably more suited here after using my noggin.
