FWIW my tale: back in 2008 my 92 NA manual lost 2 injectors with way out of ohm spec, shaky running. Didn't want the same pintle type injectors so my other choice back then was 300Degree fuel rail + upgraded to 6 pintleless 93+ OEM injectors + SS AN fuel lines, I did the transfer and grind the plenum for future injector R&R if needed. I would rather have had lower injectors adapters for the stock fuel rail but couldn't find at the time. The Z runs better with the upgraded pintleless injectors and 300Degree rails and a fuel mileage increase.
