2015 Mustang Ecoboost K/SA?

Okay, so now that I understand what's likely going to happen to this combo- What if I built one in a somewhat less casual manner (to avoid having to buy stuff twice), keeping in mind that it's probably going to end up in F or thereabouts in the reasonably foreseeable future:

Smaller/lighter drag-type brakes that would allow fitting 15" wheels, light-ish drag-type 15" wheels, 275/60 drag radials, drag-type springs, drag-type shocks, and a drag-type converter for the stock 6R80 transmission...

...in addition to the previously-mentioned 3" off-road downpipe dumping open under the car, colder plugs, and "tune" of the OEM engine/transmission computer, on an otherwise stock engine and stock 6R80 transmission, in a relatively intact car equipped with the required safety equipment and fuel test fitting, and approved 100-octane unleaded racing gasoline.

The additional expense of more-appropriate brakes, suspension, and converter, would probably add about $4,000 to the original plan, which is significant, but it's not as much of a deal-breaker as the concept of having to go buy a used CJ roller, a rollerized C4, an 8" converter, a Holley EFI system, a properly-built Stocker engine, a truck, and a trailer.

If a "Baby Jet" ran 1.0 under the F index, and I was only running .2 under, it wouldn't be the end of the world. Like I said, I have no delusions of setting any records or running at Indy.
