are the b16a sirII pistons higher domed than the JDM b16a first gen pistons? so in other words, why the 8 hp difference...
 
i know the cams are different, the 1st gen b16 cams are the least aggressive of the bseries vtec cams, not sure about the pistons though, i think those are the same because the CR is the same.

The SiR is 10.2:1 and the SiR(II) is 10.4:1,but the ones here in Germany are rated at 160 even the 92-95's :huh:
 
ah, all i could find in the reference section were the ones with 10.4
EDIT:
nevermind, i was looking in the wrong place, i found it :p
 
yes, i stood corrected on my last post
