So I ran across a suggestion/idea that has me thinking of an injector swap in my 2000 Navigator, and I haven't been able to find definitive answers to certain (very important) questions that I'd prefer to know before I even consider moving forward with something like this.

(1) what pressure are the stock injectors in a 2000 navigator 5.4 DOHC?

(2) what pressure are the stock injectors in a v10 motor?

(3) is what ive read correct in that the navigator injectors have 3 holes and the v10 injectors have 4 holes to spspray fuel?

(4) would swapping v10 injectors into a navigator DOHC motor be worth the time, money, and effort?

Thanks in advance, guys!

 

Injectors are measured in lb per hour. If they are not the same your vehicle will not run correctly as the computer will not compensate, unless you have a tune.

 

No point in doing anything unless you're going to tune it. The calibration in the ECU is set to maintain a specific configuration and emission parameters, so whatever you swap out which is supposed to enable more power will just end up having the computer holding it back, possibly to a point where it runs badly or not at all and throws codes at you. If you change the configuration of the engine, you also have to tune the calibration to enable the ECU to run the engine optimally in that new configuration...

 

What are you trying to achieve?
