First you need to get the pistons, they won't bore it without having the pistons. And also I would use b16 pistons instead of ITR they yield a higher compression, then the ITR's. Just bring them the pistons (make sure you order them .25 over) and bring them to the machine shop and tell them that you want them to bore it .25 over. And have them inspect the block, and see if it needs to be decked. It's probably a good idea to look into ARP Rod bolts also, which need to be pressed into the rods. ARP Rod bolts will make it alot safer to be revving higher.
