It probably would be better than a TT-01, but it might be a bit of work and you need to consider if you can still get parts for it anywhere.
It would likely need weight added in the back and a different differential configuration. Usually drift cars have a lot of weight up front. They also usually have a solid rear axle and a front one-way diff or a gear diff or maybe a ball diff.
For racing you'll want a gear diff or ball diff in the rear and solid axle (spool) or a gear diff in the front. Racing 21.5 blinky, you might like a diff better than a spool in the front. Hopefully you could just swap front to rear whatever diffs are in your car right now to turn it into a racer. Check that the pulleys are the same size though. Sometimes drift cars are different sizes front to back. If so, you would need to change at least one of them to match the other.
Sensorless motors are not legal for any spec racing classes, not that you would want to use one anyway and if you tried to use a 21.5 motor with a sensorless ESC, your car might not move at all from a stopped position.
If you are on a tight budget you can probably ask the race director about allowing you to use a silver can brushed motor to start out and then get a proper sensored brushless setup later. As long as you don't have some crazy fast silver can that was cherry picked, comm dropped, zapped or any other "voodoo", I'm sure they'll have no issues letting you run it.
Most important thing is to just get a car on the track and have some fun with it.
