hey guys ive heard of a b18 with a b16 head...what exactly does this do??....and whats the diffrence if i get a b16 w/a b18 head? the b16 is cheaper and i just wanted to know if it gets any extra power w/ a b18 head.. thanks
B16 w/b18 head raises compression and yes you will get more power. B18 w/ B16 head lowers compression (good for boost) and the B16 head flows a little better. This is also known as the poor mans type R because the B16 head and the B18C5 head are very similar and even cast from the same mold.

the whole deal of high boosting is getting as much low compression as possible so you dont blow your motor.
high compression=low boost no more then about 8-12 psi depends on the motor
low compression=high boost i know a kid with a b20 block that has been work on and he can run 60 psi all day (i'll to get pics of the motor for you guys)
now thats what i know so far about the whole ideal of boosting because im boosting my b18b1 (which is a ls motor) reason why because it already has low compression about 9:2 or something
anyways if i do ls-v-tec i get more compression cause of the b16 head and i dont want that.
60 psi?! damn thats crazy...yea i figured high compression ratio was bad for boosting...theres a kid here that just bought a integra type-r boosted and he only run 13's...hes only pushin like 4psi
lol cant wait to get mine done right now i have to get the kit for the turbo and im going to save up for the internal mods later on i plan on going about 12 psi(highest boost i'll go) for now on the stock ls and then when i get the money for the internals so i boost to 30 psi. just hope everything goes well.....
