    hey, i have a d16y7 in my 93 EX (i bought it like that). i wanted to get a lil more power, and get ready for my mini me swap. well, i want to get my throttle body bored. right now it is 56mm. I want it around 62mm. will i need a new valve for the inside, or should i jus have them bore it into a cone shape down into the valve, then the opposite shape coming out of the valve (into the manifold). do u guys know what i mean?? I read it on some thread a while ago, it creates a constriction for faster air flow.
