if you want to spend $1000's. there have been stock H22's making between 180-200whp in its stock form...Originally Posted by 92ex
H23's will take alot of money to gain that much....NA is hard to gain 20+whp without spending $1000's....
but if you really want to then go for it... best hp to $$ would be to modify an already good flowing head like a H22 head.
anything can make power, its just how much money do you want to spend to get there...and is it really worth the cost of "being different"
