is there that big of a differance between these 2 heads I have a d15b2 and was going to put a D16A6 head on for a little more power but since i already have an si intake and a si cam in it and a few ather things would it be worth my time

not really IMO. I think a y8 vtec head would be though.

It will make a difference though...especially when porting the head
tha A6 head flows better...

hatrack48

what if i p&p the d15

Semnos

I don't know...but I've heard the D16A6 head is the better flowing head

i donr know much, when it comes to hondas, but what about the d16a1(i think) the 1st gen integra head. would that bolt on?

Sorry dude...a d16a1 head doesn't bolt on. It's gotta be one of the only d-series heads that don't match up. If u want a dual cam, get a b series. As far as flow goes, the d16a6 does flow a little better than the b2. Maybe u should try gettin a z6 or a y8 head instead...vtec whoop whoop!

IMO, I think the setup you have already is good. Just
P & P the d15 one. SI cam & si intake sounds OK. Almost everywhere I've read the d15 breathes better into the higher rev range with the si cam.
I have a d16a6 & I'm going to a y8 head with a P & P
head. Now the vtec fuel maps & boost gets more complicated

Oh ok thanks Josh...I neede that info to
