I swapped a b16a into my 91 crx damn over two years ago where does the time go. i just picked up a b18a block that has been rebuilt with arp rod bolts, p30 pistons, and bored to 82 mm. i have two questions is the 82 mm bore to much for the stock sleeves will this cause a problem later on and will the breather chamber, water pipe, water pump, thermostat housing and so on from the b16a transfer to the b18a block. i know i have to get a gsr or tyre r timing belt and of course a new oil pump. i just wanted to know if i needed to order theses parts for the LS block. Thank for all the help i have received you guys got me though the first swap.
