The MJ is a lovely plane to fly. If you want crazy then you need to go on a hotter set up. I am on No. 4 now and she has a Feigao 3,600 KV motor and I get 30,000 RPM on an APC 4.7x4.2. She is so sweet to fly. I would say go for an inrunner of no more than 3,000 KV to enjoy it, enough speed to thrill but not drawing so many amps that you start to have to get BIIIIIG ESCs and batteries.
