looking at increasing to 555 injectors however i can see that alot of sites are saying nismo 555 injectors commonly known for lasting only a year in the 1990+ 300z's

 

is this true or should i be looking at a different brand of 555 injectors?

 

wishing to get some soon

Only worth really worth having 555 injectors if you're running or plan to run larger turbos. You'll need a new map too.

 

Not really heard anything bad about the Nismo injectors. If you want, Deatschwerks are a good alternative. http://www.deatschwerks.com

The problem you mentioned is related to the early style Injectors for the 89-94 300zx, and is only an issue in the U.S due to the introduction of high ethanol content in their fuel over recent years.

 

Its not related to the brand, its to do with all of the early style injectors, and its not something we have a problem with here. Dont worry about it.

 

What they tend to do in the U.S instead is fit the later style Nismo pintle-less injectors using adaptor kits or the later style fuel rails and lower plenum.
