ok im in the process of putting a b20 vtec together, just ran into a b16 head with crower stage 1 cams, springs and retainers, my question is, will there be that much of a difference from just a stock head, any comments will be greatly appreciated

 

It should pull a little bit harder and Increase in HP since there is a slightly more radical cam grind. What do you plan on doing with b20 vtec? All motor or boost.

 

all motor, i have a stock b16 head, and then that head with the cams, is it a waste of time and just sell the head or should i put that one on

 

My opinion, if you already have a b16 head. Keep it. The money you spend on a "semi-built" stage 1 cam'd head, you can better your self and get a more radical cam and get the head built to your likings. Just my view on it.

 

aight thanks alot man for your time,if you happen to find out out more about , id appreciate more comments

 

Port that head. The major bottle neck here is the head, not the block

 

Can't hang with the 1.6 lita. haha, yes. Ferrea has some nice valves for b16 heads i've heard. What pistons are you going with?

 

1.6L? 1.7L

 

Oh, I was referring to the b16 head I know what motor you got

 

This set-up would produce a decent amount of power, and with the b16 head with the stage one cams would help the b20 block breathe up-top. The major problem is in the rod to stroke ratio.. rev it out too much and the piston speed will catch up to you.. if the angle is too much at the right RPM and there goes a rod. Longer rods (forged) will yield a slower piston speed and less side wall force due to the rod angle and be able to handle more abuse from a longer stroke crank.

Honestly, grab a b20 crank and a V-Tec block and slap on the b16 head.
