I ran 13.3 in my Talon for about $750 in mods and 13.001 for about $1300 in mods. No none of the mods were Nitrous and I never had any breakage or reliability problems. I think that is reasonable and probably comparable to the Mustang. Keep in mind there are not some frak numbers they are my numbers and they are WAY below Average. People have gone 12.4 with a TSi AWD for less than $500.
