Re: whats the difference
I don't know for sure, but i would guess that the B16 doesn't flow as much air just because of the fact that it is on a smaller engine......i don't know if i'm right, but it will be interesting to find out the answer!!
Ace should know this one.......

I don't know if the GSR head flows better (probally does) but the only real difference I know of is the GSR has that inverted intake manifold.

Re: whats the difference
i really don't know if the head does flow better, it's more or less a guess......I assume it does because the head is breathing for a bigger engine.

Re: whats the difference
Yes the GSR flows better.
Do you want to know only about the head or whole motors? I've had a gsr and a b16 and now a lsvtec using a b16 head. If I could have afforded i'd rather the GSR head but the b16 one works quite well. gsr head ups your comp .5 i'd be sitting at 12:1 hehe

The Gsr head flows better and is a choice for head porters because of their squarer ports. The cams are pretty much the same compared to the 2nd gen b16
