For stock motor, a good balanced motor would be the P2k2 . If its a really wide open track you could try the Monster and its a tight one go with a P2k or Orion Core.
As for ESC, Tekin's G-10 and G-11 are really something. Easy to tune, loads of power, etc. Also no big capacitor to install either. This would be my top choice for ESC.
As for radio, the MX-3 is a nice system, at a minimum right now I would get a synthesized system so you don't need crystals and if you have the money go spektrum. You should be able to find JR systhesized systems on ebay easily for $100 or less and these are good too.
