12s is reaching the point of no longer being a nice streetable car. i wont say it cant be done, but it really isnt the BEST option you have especially if your car is a DD.

your best bet is to start with a fullsize intercooler, headers, rockers, and whatever pulley you can run with an amazing tune. that should get you very close to what youre looking for on street tires. add some slicks and that will be 12s, but thats only if your tune is awesome and you know how to drive.
