Brushless rustler advice

[Monkey]

Ok im selling my e-zilla with out the brushless system so figure i may as well put it in my rustler just a few questions what i have is a MGM 80A car controller and a fiago 9L and im guessing the 9L is to big for it (correct me if im wrong) so what motor would you recomend i get i will be runing 6 cells and want some decent speed but want run times of at the very least 10 minutes.

Secondly how will the rustler drivechain hold up i have a traxxas pro bal diff and MIP CVD's on the way and also have the aluminum idler will this be enough to cope with the power? i do have the steel top gear but it says that shouldnt be used with the idler so wich is most important.

Finally gearing any recomendations with the diffrent motors?

thanks for any help :)
