I have some serious concerns about life expectancy of the Nissan fuel injectors under elevated fuel pressures. It seems most kits jack up the fuel pressure in order to increase fuel under boost. Does anyone else have concerns about the possibility of an eventual injector failure and blown motor from the higher pressures that the injectors were not designed for??

 

I have seen injectors fail to open at 120 psi fuel pressure. I haven't heard of reliability issues. Vortech has been making mechanical FMU's for years.

You might ask over on corral.net (Mustang forums).

 

My concern is the extra stress and increased wear (long term)that would be placed on the injectors under the increased fuel pressure of most kits that use the original injectors......I think Greddy TT kit is the only exception with 440cc RC injectors included in the kit.
