sig+4.10s+tires obvisouly = what 1/4 mile time and what do i need simply to hit 12s

 

No 4.10s in an A4, they will kill your first gear. You need long tube headers and a cam with a tune plus like a 3,000+ stall converter.

 

You can get in the 12's w/o a cam. A whole cam swap is too expensive. Get your basic bolt ons, sticky tires, pcm tune, and torque converter and you'll be close.

Headers, y pipe, exhaust, cut out, CAI, TBB, PCM, 160* therm., sticky tires, torque converter, pulleys, 3.73's, some weight reduction, strut tower brace and sway bar. That would bring you in the reall low 13's high 12's.

 

ttt really want more info
