which head is stronger? and which head has more flow? people are saying the b16a head is better. what do you guys think?

 

They both flow almost the same. The B18C head flows slightly better at valve lift that is higher than any daily driver will see. There are flow charts on the Alaniz website.

 

thanks. i'll check it out. do you know of any other sources?

welcome newb.

which head is stronger? they're both the essentially the same, minus a few minor differences. From my personal experience w/either heads, the ITR/B16A (PR3) head flows better top end wise whereas the P72/GSR head has better low-mid range power but can lack top end power. I speak in terms of stock heads using stock intake manifolds. You can build either head up to make more power of course.

Outta the box though, a P72/B18C head will make more compression over a PR3/B16A/ITR head.

 

the b16 top end flows better than the b18c (head, including intake manifold) due to the dual stage intake manifold and butterflies, but the head themselves are about even

 

so should someone spend the extra $600 to $800 to get the b18 as opposed to the b16?

depends if you want more torque or not
