440cc Not modified 280z... could it work ?

[cesar280z]

Just a question...440cc injectors...could they be use on a regular PALLNET base rail..on my non modified L28?...without any issue?...

The ECU is designed to work with 188 cc injectors. With 440's the ECU will be injecting over twice as much fuel as needed, if they opened properly. Those are probably high impedance resistors so you'd have extra resistance in the circuit with the stock dropping resistors and they might not open correctly. If they did open properly, you'd have a very very rich mixture. If the engine even started it's doubtful that it would run once it warmed up.

I highly doubt it. You can make them fit physically, but the stock 280Z EFI isn't going to know what to do with all that fuel.
