I have the older MBX5T and the Mugen truggy you have is a great choice. You can start by going to RC-Monster's store and you will be able to find everything needed for a great conversion. Most racing set ups are using 4 and 5S lipos and motors ranging from 1900-2200Kv. Use BrianG's calculator to determine the proper speed estimate with around .5 to 1" of tire ballooning. I noticed a few set ups that don't use the tire ballooning option geared for 40mph and they seem to show some problems. My MBX5T runs on 8S lipos and I have it geared for 34mph, but with the tire ballooning it actually went a tad over 40mph radar confirmed. You can also ask Mike on his set up, I think he also runs the MBX6T as well as a couple of other members in the forum.
