Well for the turbo consider this.
Conservatively - 275FWHP & 265FWTQ in a 3000lb car with a very low CD (.31 IIRC) & and close ratio 5-speed.
Most Mustangs are toast. (brick aerodynamics and even built ones are rare over 300WHP)
Stock to modded LS1's (250-350WHP but 3600 lbs!)
So yes you will beat "most" things "from a roll" (yes the big dogs will still win - let's get real here)
However consider the significant difference - COST!, 4-doors, & thus having 3 of your buddies pointing and laughing at the bewildered driver next to you.
Maxing out the limits of the stock gearing (~166mph at 7000rpm) will be no problem at all! You'll be getting there fast too!
