Can i put SIRIO .18-TX Pullstart ENGINE w/Rotary Carb, Threaded Crank into Yokomo gt-4 RTR???
If not what is the best engine for my gt-4? PRICE DOES"NT MATTER!!!!!!
The engine fits in the same place as the 2.5 so it will fit but you'll need a side belt tensioner because it might skip the belts cause so much power. Make sure the crank is the same.
