about to go look at a 73 240z with a 280zx turbo motor with a 5 speed he said car pulls real good at 6psi and set for 6psi but car cuts out at full throttle. He said its the fuel pump and he bought a 255 fuel external pump to replace it but didnt get time. Do you think this is true. I have no clue about engine swap. Anything to look out for?
