its not too hard to get into the 12's if you can drive and have a good set of tires. I have 3.73's intake cam pullies exhaust car weighs 2800lbs and a built C4 with a trans brake and if i missed anything it is in my signature but i have ran a best of 7.94@85 in the 1/8th and that is said to be a 12 second pass. so you can get there by spending limited money like i have
Good Luck and i hope you reach that 12 second goal.
