I want to change my240z drivetrain to 280zx drivetrain. I'm not sure if my triple weber carb will bolt up to the 1980zx which has the EFI and N42 head will webers bolt on to the N42 EFI head and can I do away with the computer after i put on the webers. transmission on 80zx is 5speed will that fit in the 73 240z shifing counsel currently I have a 4 speed do I need to cut my counsel to make five speed fit and shift the car. I want to get away from that dam computer crap and give my z some more ponies without having the efi anyone have any idea's or has anyone done this before . Is it simple or a headache :stupid:

just pretend it is the same motor...the block is the same, the head will look pretty much the same on the outside as well...might be different shaped ports on the head, but that's about it. If your 73 has points, using the 80zx dist is better, as its electronic, the ignition brain is right on the side of the dist...search this, its everywhere on how to do the dist conversion.

All of your stuff will work on that motor.

No cutting up of the floor for the 5 speed, the cutting is only if you have a Series I 240z (pre mid 71). It will bolt right in your 73.

Good luck!

do I have to use the computer brain from the zx motor im putting in to the 240z to make the electronic distributor work correctly I'll be using the 80zx distributor with an E-12-80 ignition i don't want to use the computor brain to do this can this be done

the "computer brain" should only be necessary if you are going to use the EFI from the ZX. In which case you would need the entire Engine management system including all sensors, wiring, etc.

If you are just going to used the ZX distributor, the "computer brain" is not needed.

Yes I'm going to use the whole 80zx motor & trans put into the 240z & put the triple webers on it so i'de be replacing the EFI on the N42 head & putting on the webers in place of the EFI on the N42 head & using the E-12-80 ignition distributor

The answer is still NO because you aren't going to use the EFI.

If you're using carbs, all you need is the 280zx block with head attached...that's it.
