i didnt micro measure the bores on my B20, but mine looked pretty clean too,

there is a slight scuffing at hte front of the bores that indicates there is some wear from hte pistons 'cause of the sideloading, but i am told and know this is a characteristic of longer stroke engines...

so i guess it is something to examine on B20B/Z's and make sure if you are replacing pistons tha thte bores are properly honed to specs...

just a few cents,

i ordered a B20z today. It supposedly has 1600 miles from a 2001. $1025 shipped. The only problem is it doesn't have the accessories or starter, but it has everything else. I think I can use my 96 DX alternator with a pulley change. If anyone has this info, let me know. I'll let you know the condition soon. I took a chance ya know (it's coming from Nebraska heh heh).. Anyway, it has a 90 day warranty and supposedly 210 compression throughout.
