Well with the overwhelming replies I received
. I decided to just give it a try. I was just going to put the magnets from the SBP in a ball bearing can with the Stage 2 arm. What I ended up doing was putting the Mini-Z Racer Z-130-A-BB motor in with the Stage 2 Blue gear and 11 tooth pinion. Havent had a chance to test it fully but in a short drag race it was faster than the Stage 2 yellow in my sons Civic. I'm kinda thinkin that I still will want more torque however and I think I will try a lower gearing. Like the Yellow set. Maybe the red. And add the all wheel drive set as soon as Rat Shack gets em in.
