Nismo 555cc(615cc) Fuel Injector (1)

(1) 555cc/min (new style 615cc/min) Fuel Injector

When upgrading to higher power levels, stock fuel injectors are short lived as they simply cannot deliver enough fuel to safely run more than ~380RWHP. These Nismo injectors are engineered and designed to flow larger amounts of fuel to keep up with the demand as airflow increases.  Injectors are precision made and have exceptional calibration directly from the factory.  

These injectors can handle up to ~600RWHP of fuel flow capability and come as a complete kit ready to install in the "new style" (93+ Normally Aspirated, 94+ convertible, & 95+ Twin Turbo) Z32 engines equipped with the newer style fuel rails.   These injectors can be installed on an earlier model Z32 but will require use of a machined lower plenum and new style fuel rails or a 300 Degree -4 fuel rail.   ECU upgrade required.

These injectors are often referred to as 555cc injectors due to the fact that they are the replacement for the earlier model Nismo injector upgrade which does flow 555cc/min.  These new style pintle-less Nismo injectors actually flow 615cc/min.
