Thought i might add to this awesome e85 thread, during my z32 ownership there was a lot of talk about ethanol causing corrosion to injectors. In an early model z32 89-94 they ran pintle style injectors which recieved constant 12v powering the injectors even when the car is off, when using ethanol the alcohol creates a conductive bridge which caused corrosion over time. The later model z32 95+ were fitted with popett style injectors and did not have 12v powering injectors when the key is off, no injector failures have been reported with this setup.
It is a common mod in the z32 community to rewire the the injectors to only power 12v when the key is on, to stop the corrosion on pintle style injectors. On poppet style injectors there have been no reported failures even with the 12v circuit still intact. I would assume other Nissans of the same era might share similar wiring circuit for the injectors. Definitely something to look into if running e85, hope i didnt open up a can of worms
