Help me get into the 12's for cheap

You wanna go from 14.8 to 12.99 in a full weight car with 3.55 gears?

and no nitrous?

There's no way around it, it's going to cost you more than $2000. Way more.

This centrifugal supercharger kit and a good torque converter will get you there and that is probably going to be your cheapest option. It will also leave some scope to go faster again in the future too.
