I have a 1982 280ZX Turbo drivetrain in 76 280Z. The stock ECU.number is A18-601-042. I have a chance to buy a spare ECU from another 1982 280ZX Turbo and the part number is A18-603-045. They are both 5 speeds.

Does anyone know if these are compatible?

TIA

This Nissan guide says that the second one is for a 1983 Turbo.  You could browse through the FSM EFEC sections and see what might be different.  The ZX's got so packed with emissions devices, it's hard to say what might have changed.  I would open the wiring diagrams for the EFEC systems and compare.

Thanks for the help. I will check out the diagrams!
