converting a XB8 to brushless

Glassdoctor,
I just won a jammin CR buggy, my buggy that was selling his xray backed out. I wanted to set it up similar to you losi 8 because I already have an 8000mah pack for my xxxt. what style motor mount did you make? I wanted to do the top motor mount and split the batteries. do ou have any motor recommendations using two 8000 packs? I wanted to go cheap for now and pick up the MMM when it comes out. I am going to use the mamba ecs though from the start. any suggestions with the buggy?

thanks,
B
