Not sure about the 1275/1310 but the g13b is one of the easier swaps as far as modifications to the body, but as with all alternative engine swaps they do not go straight in. For the G13B you would require a custom frame etc etc. But there are number about so maybe someone on here who is doing one or has done one can better inform. The only thing about the G13B is that most engines have done plenty of Km's and would require a rebuild most likely.
