Are you kidding me? Google. Youtube. Took me literally five seconds to find these.

Every set-up will give you different result. Use these purely as references to see what you could possibly make.

like i said ive heard didnt quote it....
well since u seem like you kno your stuff unless u look up your answers on the internet... they made three diffrent motors for the crv (over the past years) do you kno the size on the blocks or the specs???? because all u keep saying its a bored out b18 when i still don see how they will match i have my money on the bored b18 that will take a b20....... remeber were talking about the block (stock).......

correct me if I'm wrong, but it is the volume in the combustion chambers. Honda essentially bored out the b18 and put b20 as the code.
that's why the walls are so much thinner.
don't know what motors you are talking about, but if there are 3 versions, the differences are probably similar to b18a vs b18b, or, the d16a6 from 88 vs the one from 91. couple hp gains, nothing significant.

do you understand what actually determines displacement?

but the whole thing is i still wouldnt compare b20 with b18 even if bored our what you think?

Seriously, tell me what you think is so different.
Stock block for stock block, the b20 is just a bored out b18.
The b20z is what they used in the CRV.
Any B20 prior to that was the useless Prelude bastard motor. NO similarity, nothing compatible.
The difference between, say, a 96 or a 98 might be 1hp or so. Same goes for a b18a/b of a year difference.
So why wouldn't you compare a b18 to a b20?
Both can convert to VTEC
B20 will crack cylinder walls
B18/B20 both have the same potential, and will cost about the same to get the same numbers, no? Why? Because they are the saaame.
Yeah, compression numbers are relative to displacement by the way. Taking THIS much volume and compressing it to THIS much.

small compression numbers!? are you kidding me?

I gotta admit man, that does not sound good. Tapping noise? Why would there be a tapping noise just because its a vtec head on a non-vtec block?
And why isn't your vtec wired up? What ecu are you using?
Runs rough when you start it up? ehhh....
Did you end up going with the b20 block/gsr head/gsr tranny combo? what pistons? If I remember right, you were using 10:1 compression pistons? Have you changed the oil since the break-in?
tell us more!

no i havent changed the oil yet...im using a tuned ecu a p72...
n yea the tapping doesnt sound good to me either...
