full suspension, slicks, h/c/i, gears will defintly get u in the low 12's maybe if u just do a full suspension and gears, a few boltons, and good drag radials or slick u can get low 13's, mid 12's, but its really all about traction, and of course u have to have some power, but traction will get u ur 60' times which help in the long run, thats when u would need the power goin down the track but if u have no power u wont be able to get it down, well in the end i would say 3-4k for low 12's depending on what u do, or u could be an awsome driver like 25th who has bolt ons intake and drag tires and runs 12.6's
