G3R motor recommendations

I've got a g3r with an e-maxx tranny, 14 cells, revo talon tires and 18~24/66 gearing options.
I want to replace my hv maxx 6.5 system with a mamba max and neu motor.
Will Neu 1515/1y be fine?
What is the best motor for my setup?
Please give me some recommendations about the motor selection.
