sc18 what is best brushless system and pinion teeth # to use

I saw a CASTLE CREATIONS CM2068 MAMBA 1/18 BRUSHLESS SYSTEM COMP PACKAGE how would that work. the sc18 is belt driven so could it handle it.
thanks.
if not how would the CASTLE CREATIONS CM2068 MAMBA 1/18 BRUSHLESS SYSTEM COMP PACKAGE work in my rc18mt and at what gear ratio?
