I converted mine over 4 years ago with a motor that you now know as a Neu 1515 1y. The power is almost to much and with the castle mamba monster it is too much. Almost. I use the oil weights already that you mentioned except I use 1000 in the rear. Would using the 3000 help me get better traction? I can spin my tires down the straits without ever really hooking up. Right now I'm running on an indoor track here in Huntington beach. I can't wait to take it to an out door track.
