I'll chime in here.....first off if you are just starting out in offroad you DO NOT need the most powerful engine to start off with. Secondly when you are on the track it is not the same as driving in your front yard in the grass with tons of traction. My suggestion to you would be to fix your current engine, buy good tires, and PRACTICE. The only thing a faster motor will do for a beginner is break more parts. You can come to the track in Miami and see what the fast guys are running. My suggestion to you is fix what you got, get some parts, and some MS K2's with stock foam. Just my suggestions...
