Mugen MBX4-XR Conversion?

I did a comversion on a MBX4-RR. Link is in my sig. The MBX5 mount bolts up perfectly.

Awesome, after converting my Rustler to a drag racer I have an itching for a reliable basher and I think my old MBX4-XR would do the trick. I know parts are getting hard to find but nitrohouse.com still stocks parts, ebay, and I already have another parts buggy. I think I am going to run the Medusa 2000kv-60 on a 5s. What pinion should I order with it to keep it cool? What about the Medusa motor with the heatsink? Would there be enough clearance for the heatsinked motor to fit?
