I will post the facts of the mustang, you can use them how ever you wish. but dont assume your car will run this or that with out having hard core time slips. All of these times are give or take a couple tenths. I have been in the mustang sceen for 5 years and I KNOW what I am talking about when it comes to mustangs. These times are for average drivers in average cars in average alt. and average weather conditions. A higher alt. can make a car TONS slower so remember that.
94-98 mustang V6 auto runs 16.5-16.8 in the quarter stock, manual 16.1
99-03 mustang V6 auto runs 15.9 in the quarter stock, manual 15.5
94-95 GT runs 15.0-15.3 stock in manual and 15.8~ in auto(the better 3.08 rear mustangs run a couple tenths quicker)
96-97 GT runs 15.0-15.3 stock in manual and 15.8~ in auto(the better 3.08 or 3.27 geared mustangs run 2-3 quicker stock)
98 GT is a tenth~ faster in each area (10more hp)
99-03 gt runs 14.5 in auto stock and manual 14.0.
My 01 V6 with (CAI, exhaust, Gears, Tlok diff, UD pulley, and wider tires than stock) ran a 14.73@93mph 2.15 60ft. Stock i ran a 15.5-15.6 with a rare 15.4 average 60s are 2.2~
thats the facts for the mustangs. I really cant comment on the imports but a civic ex only has a chance (CHANCE) vs a auto pre 99 v6 or manual pre 99 v6 which i doubt stock would even take either one of them. but its not gonna run off and leave you either. Even the SI civics cant take a stock 99 up manual driven well(its a drivers race really). at least my friends never has been able to take me, and now he has a bit of mods and still loses miserably. a GS-R shoudl be good for low 15s stock? or does the later years have more power than a 95?
