Has anyone done it where it passed an emission test? If so how much did you port?

QUOTE (Smaay @ Mar 18, 2014 - 9:55 PM)  porting the head will not affect SMOG Just the man I was hoping to reply. Now is there a limit to how much you can port? Or any porting won't affect smog at all? The sniffer seems like it'll be able to sniff it. -------------------- |

how will a sniffer in the exhaust smell anything in the intake?
porting only improves flow and increases the volume a tad, and i stress tad. the O2 sensors will adjust fuel trims. you will be fine. -------------------- 2001 Celica GT-S Turbo

I meant wouldn't the sniffer be able to sniff the exhaust fumes being too rich or too lean? Isn't that how the camshafts gets sniffed out?
