Sorry if this has already been beaten to death. I have a '74 260Z (build 3/74) and I would very much like to install a more potent alternator. I understand that the swap for 240Z's won't work due to fuel pump and seat belt interlock issues. I plan to go with an aftermarket fuel pump which I will wire from scratch with its own relay and oil pressure cutoff. The seat belt interlock was defeated by the previous owner and it looks like it was done by securing the emergency start button in the engine compartment in the permanently down position. I will not have too much electrical load - the only increase would be halogen headlamps and a slightly more powerful radio (50 w driving two 8 x 11 speakers). A while back, a forum member named "bambikiller240" said that he had a method for doing this swap on a 260Z and one could contact him for the info. However, he no longer appears to be a forum member. Does anyone have the details of the 260Z alternator swap? Thanks in advance for any suggestions.
