what do you make of this piston

this is one of the pistons from the b18a block in my 93 integra RS.. i have a new block in my car now.. but i'm trying to figure out what the 0.8 means below the PR4 raised lettering on the piston..
my PR3 pistons in my new b18a block have .25 for being oversize pistons.. as far as i know, honda doesnt make any bigger than .25 oversize.

hopeing someone here can tell me what this 0.8 is on my pistons.

all I know is that if those are your pistons in a running motor... It seems
you are way lean. There is no layer of carbon deposit on the piston...

Re: what do you make of this piston (MikeSarr_GSR)

LOL i took my diegrinder with a wirebrush wheel and cleaned the top of the piston so i could take the pic.. as u can see there is some carbon on the piston, i was too lazy to take it all off...
what i really need to do is get my caliper and actually measure the cylinder to see what size its at. i've been too busy with work and troubleshooting codes on my new setup to worry about my old block.
