Haha I love these questions... try going 12's first and see just how that is.
I can tell you one things by the time your looking at the 9sec class you will already know the anwser to your question.
In a car like that i'd say cut all the fat you can. Lite as possible...
Then forget whatever drive train is in there...
New rear*built* new trans*built* and a wallet opening engine. BUT don't forget you now must run full inspected safety cage you should already have something close to slicks on the back. A suspension that is in the order to take a beating. O and be able to control the car as it lifts the nose off the ground *very fun
Then find another car to drive home in because by then your past street class. *a few out there but I think safety first* O and maybe a tank of fuel?
Very possible just work your way up there. Once you start makin good times it becomes addicting! Good luck.
