On my 8ight-E, I can do wheelies with the 2650kv on stock gearing. Its got plenty of torque. Can't go wrong with either. There is almost too much power with the 2650kv. 2200kv will work as well and probably recommended for truggies/monster trucks. 2200kv in a buggy would make the power more manageable. Its also less critical of gearing changes.
