I've been toying around with the idea of purchasing a used 2005 and up Dodge magnnum. Since the SRT-8's are going to be out of my price range, I was thinking of getting the 5.7 version. What would it take, given the limits below, to get it to run 12.20 or under in the quarter? I wuld really like an 11 sec magnum.

limitations:
-daily driver(start and run every day, summer, winter, creature comforts)
-no weight reduction (removing seats, AC compressor, etc)
-NO NOZZZZ....
-superchargers and turbos ok
-must meet NJ emissions limits
-suspension mods ok, but must not detract from cornering and braking
-include drivetrain upgrades if necessary.

can it be done? and at what cost?
