Not to my knowledge. The RGT Bowler uses a 390 motor and the motor plate that comes with the stock tranny won't fit a 540 motor. You might be able to modify the motor plate on the Bowler's trans to accept 540 motors, but the gears are all plastic, and may not hold up to the additional power.
But you can buy an adapter that bolts on to the Bowler's skid which will allow you to install a regular Axial (or clone of Axial) three-gear transmission which is designed for 540 motors. A seller named jamachuca from Spain sells them on eBay.

I put one in my Barrage, and I'm running a 540 motor now. I'm sure it would also work just fine in the Bowler.
