best head for b20/vtec???

[corey30349]

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

[Annihilation]

I'd go with GSR head with sk2 intake manifold

[twinj]

I GSR is better. I can't really explain why.

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.

[mitch lab]

b16 or b18c5 just because they flow much better

[Ltdnismorace]

are you saying that a b16 head flows better than a b18c1 head?

[mitch lab]

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.

the SK2pro series is a drastict improvment in air flow over the stock gsr intake manifold...thats why i would pick this setup over a b16

[rhdeg2]

and it gets rid of the secondaries

[Krappy]

get a nissan and do a SR20VET RWD setup.....

[xenonvisions]

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

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?

[Sol-Badguy]

True, I like the secondaries.

[corey30349]

bump

[speedminded]

get sleeves pushed in and prolly light weight crankso stock rods & pistons in a sleeved block with a knife edged crank?

[corey30349]

so stock rods & pistons in a sleeved block with a knife edged crank? 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 slow

[VTECrrRREADY]

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

It's a honda.
