what does a b18 bored .40 over equal to? will stock b20 pistons drop in? if not what pistons will i need for this motor?
.20 over is about 1mm if I am not mistaking. B20s are about .60 over from an LS.

sweet, thanks guys for the help
No problem.
so would these work?
http://www.jepistons.com/Catalogs/SR.../b20_b16a.aspx
no, those are all 84+ mm pistons
.40 over is an 83mm bore.
oh emmino told me i needed 84mm. so bacon, i need 83mm correct?
He would know more than I would but if I wasn't mistaken, .20 over for every 1mm.
man this is confusing me lol. ive been researching but i cant seem to understand the numbers
81mm bore is stock LS
84mm bore is stock B20
I am under the impression that .20 is equivalent to 1mm which would make:
~.20 = 82mm
~.40 = 83mm
~.60 = 84mm
Like I mentioned before, Emmino would know it better than I would.
see thats the info ive been trying to get. i mean it sounds about right to me but ill wait to see if Emmino will confirm that its right i guess before i order the wrong pistons
Is the block you are working with already bored out?
yea its bored out and he said dual sleeved? i havent bought it yet cuz im researching about pistons for it.
Dual sleeved? Not sure what that could be. Maybe Dart sleeved
idk to be honest lol. maybe dart sleeved. ive never seen the block, my buddy told me about it.
im just trying to figure out what piston mm this block is

Emmino was right. My lack of knowledge in that field is retracted.
.20=81.5mm
.40=82mm

That is wrong bud...
.20 over is 81.5mm
.40 over is 82 mm
haha.,. damn
I found out the hard way a few years ago... lol
11.7@116- All motor H2B Integra
ok so if emmino says i need 84mm, isnt the stock b20 bore 84mm? i couldnt just take my b20 pistons and drop them in?
Me too.. Had a B16 (didnt know it was 81.5) Had some 81 mm CTR pistons for it.. Well yea.. while putting it together found out..
What size is the block NOW?? Stock, or it has been bored already?
If its bored already.. then you need pistons for that bore
Reading owns you. See my last post where I corrected my mistake.
the b18 block has already been bored and sleeved. the only thing the guy told me was that is a b18b1 bored .40 over
how about get someone to mic it out so you will know exactly what size it is?
11.7@116- All motor H2B Integra
because no one around here is smart enough for that haha.
Take someone with you when you go to buy it. Have that person measure the bore and see what exactly it is.
If it's 82mm, it should measure 3.2283464566964 roughly.
What side of town are you on? Regardless of the current bore size, if it is .040 over you still have a little room to play with if need be.
x2,, Take it to a Local machine shop.. and they can easily tell you..
hell you could do it with a damn Micrometer if need be
holy fuck, 39 replies and I answered the question in the second post. lol.

i live in columbus ga. and im jsut going to take it to a shop and get them to mic it out. seems like itd be way easier that way lol
Depends on if its really sleeved. I have darton sleeves but they are the small ones, 82mm is the max you can bore them out and still have the thickness protection.
11.7@116- All motor H2B Integra
Thats because your a homo and noone believes you
Smart move
11.7@116- All motor H2B Integra
Haha. true.. But then a Certain someone.. Starting saying the wrong Info.. THen the OP started asking weird questions again..haha..
Gota love it!
I just assumed it was invisible, but the homo thing may be it. I'll have to fix that.
The EMPIRE
ha thanks guys
I never said Emmino was wrong though.
