I have a 93 ford mustang gt with bbk headers n x-pipe
My question is if I get a 70mm throttle body will that affect my smog performance ? If yes, how ? Is it a big difference in performance also ?

if they see it they might not smog it. They are pretty strict. Just had mine done on FRIDAY. he almost wouldnt do it because of msd cap/coil and Ford racing wires. I told him they were stock on a cobra. [Big Grin] they even check your timing.

edelbrock 65mm t/b would fit your combo better, and has a CARB # stamped right on it so it's CA legal for smog.

If you have a stock intake don't bother changing the TB. It won't gain you anything. Next up I would get a Cobra, GT40, or TFS intake with a 65mm TB.
