so i have a b20 block that i had a set of rs machines itr 84.5mm pistons. motor was assembled with ptw right about .0018 ran great at that for 17k miles before i pulled it and sold the head. while in storage it got some crap in cyl 1 and it slightly marked up the very top of the bore. i can get it out with a hone, but it will open the ptw up a tiny bit up around .002". would that be too big to run. id be using je proseal rings so i can gap to whatever i want.

id probably make it a daily driver either as a b20vtec generic build with itr cams/valvetrain or an nonvtec setup with some crower either 403 or 404s. i havent decided which one i have most of the parts to do either setup
