To make a 12-second AWD 1G all you need is some race gas and removing some parts. Drop the entire exhaust off the car at the track, hack the MAS just a litle bit and unplug the vacuum hose to the wastegate, then run 12s if the clutch has anything left.
That's also assuming 150 psi in most of the cylinders and a fairly recent tune-up. That's a lot to ask in some cases.
That's alot of sound-deadening! That's awesome. You're going to have a pretty sweet and comfy DSM. A 2 door, hatchback, luxury car with a roll cage and 3.5" exhaust. Nice!
