I've done a search and found that people say all sorts of things.

I'm eyeing 2 B20B's, both claim to be straight from Japan. The code is B20B, one has a tall IM, one has a short IM but its not an LS IM. The tall IM one is a 97, and the other is a 96. I'm wondering which one of these have the 9.6:1 CR. TIA

 

Tough call, too bad you don't know which car they came from. One guy said that every one he's taken the head off had the higher comp. pistons. Another guy said that his Orthia b20b had the same pistons too despise what the jap honda site claimes...

dude, honestly,

if you dont know which car it came from - you aint gunna find out what block you got...

this whole B20(?) stuff is a bit of a wild goose chase to me.

from my research, it appears that unless you *know* which car it came from and what month/year it was you aint got anything untill you oull the head off...

even then i couldnt tell you which pistons it should have...

maybe someone else could help you answer this one.

t..

 

PS what are the first 3 numerals after the B20B...?

 

They both only said B20B on the block, I didn't get a chance to read under them, but I can on monday.

 

ha har!!!!

i am getting this confirmed reguarly enough to believe it:

ALL JDM B20B's ARE 9.6:1 CR

anyone know if this is not true?

t..

 

not true!

Anyway we ended up picking up a '99 JDM B20B with a stock LS IM. Hopefully its 9.6, if not, I'm sure it'll move anyway!

 

do you know sombody who has a jdm b20b and confirmed that the pistons were not the Z ones?

 

???

enlighten us? please!

t..

 

Well, I base this referring to the 2nd post in this thread.

 

well, i made the second post. But its still stands that every post i've ever read from a jdm b20b engine owner who has checked has said its got the 9.6:1 pistons. On this site and another. One guy even claimed that he's had the heads off dozens of them, and they're all the same. Thats all i know.

I thought b20b's had the big intake and not the ls?
