Need a good set up from you xmod "tuners"

so heres the deal...

i have 2 first gen chassis that are basically stock, and an assload of spare parts.

so im taking all my best parts and making one killer chassis to put my subaru body on..

all the metal bearings and awd kit and stuff.. and of course im going to want to up the power some... now its been prob 4 years since ive been into xmods... last time i remember playing with them i put a 6 cell on my stage 1 stock motor and it ripped ***. but i was thining that when i changed to the stage 2 motor with the 6 cell it was slower... i cant remember... and i havnt been able to check this yet...

so i have the stage 2 motor pack...

yellow, blue, red, and white. and then the white stage 1 motor (stock)

as nice as it would be to just go lith ion, i got better more important projects to blow my money on.

so my main question is using added normal bat cells, which motor/cell combo will prob be my best choice.

im not drifting or drag racing or anything in praticular, i just want a quick little xmod to mess around with at indoor car shows and stuff.

thanks for the help guys.
