Will a nismo fuel pressure reg do anything on a vq30dek n/a?

 

no.........

 

Too vague of a question. So you get a semi-vague answer.


If you don't know to do with it, no.

 

I think it makes it richer...at least the default setting? I'm not totally sure

 

If I purchase a nismo fuel pressure reg and install it on my 5th gen maxima
(vq30dek) and I increase fuel pressure will that make a big difference in performance?

 

no..........

still the same answer.

1. if you increase the pressure you have to get larger injectors
2. if you increase fuel, you have to increase air
3. if you increase fuel and air, you have to let the car know (reprogram the fuel/air with the ECU)

 

No you don't.

 

ok so is it confirmed that if you add a nismo reg to a n/a 5th gen it will do nothing for the car?

 

If you had a bunch of bolts ons, went to the dyno and your a/f is wack then sure it can help. But an AFPR on its own is so crude and pretty much useless unless you were either super rich or super lean.
