hey all, my buddy just gave me his D16z6 head with 30,xxx miles for free, and its in prime condition,and i'm throwing it on my B7 for a nice mini me.i still need the dizzy and an im, so my question, is a y8 im bigger to flow more air than the z6 im. i saw it on a web site that it was, but i thought all the D series were the same, and can i put a larger oem throttlebody like a 60mm?, instead of the punny 56mm thats on most civics. thanks
