is it possible to drift an all stock or somewhat modded box?

 

Yes and No.
Stock, all Scions are FWD. This means that these vehicles do not have the ability to use throttle to control oversteer, which is typically what most people would associate with the sport of "drifting."
However, A FWD car can be forced into an inertia drift, or Scandinavian flick, by a quick overcompensation initially made while beginning a turn, causing the rear of the vehicle to swing outward. This is typically done in conjunction with a quick yank and release of the e-brake to help break the traction of the rear tires.

 

haha UV7 knows what he's talking about...very nicely put...
almost like listening to Bill Nye

 

awesome!

 

I guess a less "Bill Nye" answer would be...
Go find an empty parking lot on a wet day, turn off your TCS, build up a little forward speed (nothing too crazy), then yank up on that e-brake while turning your steering wheel hard over. Voila! You're drifting (well, sort of...).

 

There are tutorials on youtube if you search for them
