I haven't seen any solid directions on what resistance coil to use when running a 240/260z with the 280zx E12-80 distributor upgrade.  I read some stuff that said to use a 3.5 ohm coil since the ballast resistor was gone, but then other forum members recommending a 1.5 ohm unit.  Regardless of speed part recommendation, what resistance coil should be used?

Nissan spec'ed 0.84 to 1.02 ohms for the ZX system.  I'm a big fan of using the factory spec's if they do the job.  They also spec'ed .039 to .043" plug gap with that set of parts.

Just head down to the parts store and order a coil for the zx and you should get the right ohm coil. Ordered a coil from Autozone I think, Durajunk, worked great. Ran my plugs at .040
