I was wondering about which head would be best for a b20 vtec motor some people say gsr and some say b16 which one would be better and more reliable

I'd go with GSR head with sk2 intake manifold
Last time I checked, SK2 manifold doesn't help an NA motor much at all. It's for boost applications.Originally Posted by Annihilation

I GSR is better. I can't really explain why.
b16 or b18c5 just because they flow much better
are you saying that a b16 head flows better than a b18c1 head?
the B16 head is known to flow better in stock condition than the GSR head does. b18c5 which is itr , port and polished from factory of course it will flow even better. Basicly budget wise.
and it gets rid of the secondaries
get a nissan and do a SR20VET RWD setup.....
nice set up krappy..
somone said that gsr has two stages of vtec so it would be better to get b16 so it pulls all the way threw
lolol, butterfly's in the intake manifold is not VTECOriginally Posted by corey30349

First, what's the purpose of the build? Second, what's the buget?
The B18c5 [ITR] head is a mildly ported version of the B16 head. Your weak point on this setup, whether a B16 or GS-R head, is the B20 block... what do you plan on doing to it before even putting the head on?
get sleeves pushed in and prolly light weight crankOriginally Posted by speedminded
so stock rods & pistons in a sleeved block with a knife edged crank?Originally Posted by corey30349
im going to get proble new pistons and rods also might as well say built cuz if i do it i want it to be fast and realiable cuz one dudes got a b20 but its slowOriginally Posted by speedminded
True, I like the secondaries.
bump
arp rod bolts is a must for a lasting ls b20 vtec everything else just re inforces it but if u dont change the rod bolts they will loosen up n throw that rod out the block
