sensored motor for mamba

Hello folks, 
Iys been a while since I got my jxr enroute but never got the tyme to slide it. I even had the kit put up for sale but luckily now im getting some time in which I beleive I can build thee kit and start slyding with the fellow drifters here.. nao lets come to the point.
I have all the stuff in my kit ie mamba max pro enroute servo mt4 receiver but the motor. I would appreciate if you guyz could suggest me a good brushless sensored motor which I could use with  my mamba max pro.
Lately ive been doin some research on the net for the motors which has further made it difficult to buy because many drifters say 13.5t is good while thee others say 8.5t to 10.5t are ideal...

Btw ive goot a new r34 body which I have painted in red/metallic black.. will be posting the pics of the build soon.

Thanku evryone for maintaining such a forum for the rc lovers.

Cheers
