RE: difference between mr&jx ninja
Unfortunately, they are not interchangeable since they are made by different manufacturers. I do know that parts are interchangeable between the MR Ninja and the new GRP motors. I do not know the specifics as to what is all interchangeable though. I'm sure the piston/sleeve is though. I drove a truggy with the MR .28 in it. Very fun to drive. Probably too much power, but that thing had torque for days and great top end.

RE: difference between mr&jx ninja
Yes all the GRP parts are interchangable with the MR Ninja engines. As for the JX engines, The case is the same as the XZ engine, the piston / sleeve / rod the same as the OS Speed V Spec, and the crank is from the Speed Spec minus the tungsten weights.
