Sorry ,forgot about checking the manual ,but I seen the orinal Gt 2's RTR did come with a Kyosho
pull start engine ,so I am quite sure they will fit!
Some other brands did have fitment issues because the engine mount interfered with the pull start back plate ,
the back plate wouldnt bolt on...
I have the Kyosho MP9I4 ,I currently have my engine off ,I can check ,I also have the manual
that I can look an see if there is an optional engine mount!..:cool:
