270cc for NA's, and 370cc for TT
Phase I "Early Style" fuel injectors were prone to corrosion on their electrical connectors as well as internally; ethanol in today's fuels quickly erodes the connections to the solenoid coil and causes premature failure (this can be verified by ohm-testing a fuel injector).
Mid-cycle, Nissan switched to a superior Phase II "New Style" of fuel injectors, which has a revised design featuring sealing electrical connectors and a "pintless" design, less susceptible to failure caused by ethanol content in fuel.
See the table below for info about when specific years/models made the switch.
