I'm in the same situation.
Look for a motor between 1900-2100 kv if you will be racing. ESC that are ratad at least 150A.
This is what I have benen told.

Tekin, HW, Mamba monster v.2, Toro or Reds are just some of the brands. You can probably find a esc/motor combo from each brand if you want. Reds will release their esc in march.

If it's possible go to your track and talk with the guys there, easier to get info and maybe you can try some different combos.

Hope it helps!
