ok... i was just wondering... whats the difference in the head off a b16a2 and the b18 gsr engine... ? or is there a difference... and when your building an LS/vtec.. which head do you use? im not doing this... it was just on my mind... lol

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.......:grinyes:

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.

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.

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

i had a feeling the gsr head was probably better in some way but wasnt sure... heres another for you guys if you dont mind... is there a difference in the ls block and the gsr block? probably... lol

your asumption is correct.

the are not the same block.

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

your asumption is correct.

gsr has knock, oil squirters and a girdle
