Not true at all, several B series motors make more power, particularly the B18CX's, and the H22 has a completely different head than the F22B does, not just that it has VTEC.
Look at the pics.., the only difference between the H motor and the F pictured above is the head characteristics. Yes, the H head has much more internally in order the be vtec capable, but what it comes down to is that both heads are dohc, one is vtec, one isnt. the block casting is exactly the same on the two motors as well.
as far as the more power then a B comment, i partial - failed. lol. the b series comes with more juice in some instances, but that is with the upgrade ITR valvetrain from factory as well as the bump in compression. i think if you treated this motor to the same treatment from factory you would undoubtedly incur AT LEAST measurable similarities, but i would expect that an f motor with a built valvetrain and higher compression numbers would easily surpass the 210 crank hp mark that the b series boasts. i would go as far to say a simple tune would allow for 200-210 hp.
my .02 anyways.
pix arent everything. the h block and f block are not the exact same block. materials of which they are made of come into play big. not to mention dimensions. either way they are very similar and yet very different from each other
as i mentioned before f block sleeves are iron, stronger, like boost alot more because they don't distort like the walls of the H series under high boost=power=heat.
f22 has a bore and stroke of 85x95 respectively for a displacement of 2156cc whereas;
h22 has a bore and stroke of 87x90 for a displacement of 2157cc
so i would argue that their dimensions being different is really no argument for the difference in motors overall. one cubic centimeter is hardly enough to base such an argument on..
i said the h and f block are the exact same block and the difference is in the heads, and i was wrong, but c'mon a cubic centimeter?
the real difference between these motors in question (the f22B dohc non-vtec and the H22A vtec) is the head respective to each motor. one is vtec, one isn't.. yes blocks have miniscule differences and yes as mentioned the materials are different, but what your arguing is like saying a macintosh and grannysmith are two totally different things ... when it comes down to it they're both just apples; and we're not comparing them to oranges..
