Rustler setup - am i on the right track?

[Candyman2]

Looking at:

warrior 7020
fiegao 380c - 6T

running on between 6 and 9 cells.

Looking for a fast little rustler, I have been running 7 turn motors and its just not enough so hoping this will blow my wig off, fit in ok, use standard pinions? not overload the speedo?

Rene im looking in your direction!
