Make sure that the ESC you buy is on the ROAR-approved "Blinky" list:

You mentioned in your original post the Turnigy Trackstar 120A Turbo #9192000048, and this is approved. I have used one for both VTA (Touring Car) and Street Stock (dirt oval) with good results. Make sure you get the correct programming box: "Program Box for 80A/120A Turbo ESC", #9192000049.
