I'll echo what guys here are saying. I've been racing a long time and the guys that do the best are the ones putting in laps. They may not have the fastest hero lap, but they definitely are consistent lap after lap. I think it would be a good idea to find a decent used motor on here ( guys are selling motors all the time because they want the new motor of the month). Even buying a good used esc on here isn't a bad idea. Then spend more time at the track. Don't just put in mindless laps, pay attention to the fast guys attention and how they drive. And keep your car in good working order.
