Click for larger image	NISMO 555cc 740cc Injectors Getting more ponies from larger turbos or nitrous oxide puts additional demands on the fuel system. The additional airflow means that a greater quantity of fuel will be needed for a proper air/fuel ratio. As boost is increased (or nitrous is introduced to the intake charge), the EPROM has the ability to make minor adjustments for the increased fuel needs via the stock 370cc injectors (259cc for non-turbo). However, when it reaches a wide open throttle condition, the stock injectors cannot deliver enough fuel to efficiently and safely manage flow. By going to larger injectors, horsepower potentials can be achieved and proper air/fuel ratios can be maintained, avoiding a dangerous lean condition. The engine ECU must be reprogrammed to make use of these larger injectors. We strongly recommend ordering with the O-Ring Kit. *NOTE: On early model (90-93) 300ZX, the 740cc injector upgrade requires the fuel rail from 1994-96 300ZXTT.
