What kinda gas milage changes would there be with a set of Tomei 268 cams? or even the 264's

Any thoughts on streetability would be great....Would the car stall every once and a while with the 268s, or would it always be able to hold an idle? any other problems that would affect daily driving? I drive about 75 miles to work and back every day

As for idle, NISMO recommends raising the idle with the installation of their cams, which are milder than the Tomei's, so I would definately have at least that much done.

As for gas mileage, all depends how you drive it....the stock Z stinks on mileage when you are really on it.

 

I wouldnt do it if you use it as an everyday driver..gas mileage will be horible....Well at least worse....altho I was getting 26mpg with my procharger @ 65mph...For like 1 mile, then I couldnt take driving the speed limit

 

But say in my normal everyday driving I stay below 3500k would the milage still be heavily affected?

Sure it would..Even at idle you will be running more aggressive cam durations causing the engine to burn more gas..Any mod you do affects the gas milege...

 

I completely understand that my milage will be affected no matter what I do, but what kinda difference is it gonna make? I can live with 2 or 3 MAYBE even 4 miles a gallon difference, I just wanna know if anyone knows how much it is going to change.

Well its not gonna go from 23mpg to 12 if thats what your afraid of...I just think nobody really knows how much..If it concearns you that much then dont do it and be safe..

 

But I wanna :-( lol......

23mpg? I drive 80% freeway and never go above 20.5

really though- anyone here have Tomei cams? or know someone with them?
