Anyone here have a 260Z that they've converted to round top carbs & have been able to pass emissions? I want to pull off as much as I possibly can.

My suggestion would be to pass smog first then strip evrything related to smog off. I had to do that when I lived in Ca.

get a bottle of fuel additive that should be near the lead additive and the nos stuff at pep boys or the like. it says it is a 100% sure to pass your car at emissions or your money back. try it and it will probally work. where I live if a car is more than 25 yrs old it is emission exempt. good luck with the govt.

I'm in Az also. Tried to pass 7 times in the past 2 yrs finally got a waiver barely under state level. Tried additives/ racing fuel/ benzyne/ inj/ all vacum hoses replac- Still failed. Registered car out of town = No more emissions. Just go online and do it, no questions- no prob.. just pay ins. and all will be well.
