Default 2 speed help.

Last year I put the HPI 21BB motor on my super nitro rs4. Right now I am running a 18 tooth clutch bell and stock 44 tooth spur gear. And it's got some killer lag. I am trying find a 2 speed for a .21 motor that I can use the rest 2 speed that I had with my .12. It's a fast car once it gets up to speed but needs to be quicker of the line.
