just a heads up for the guys interested, i believe the only fpr with gauge that truly is "strap on and go" is the FSE one rpw sells.

glad to here install went well. i might be getting an fpr in the future too

 

i thought u planned to boost? if so it would be a waste of money...

 

AEM FPR for a Civic fits. I have one on my car.

 

This may be a stupid question and I haven't bothered to search it, but since I'm not starting a thread about it and its on topic, sort of, what exactly is the benefit/use of the FPR?

 

correct me if i'm wrong, but on the contrary, its a rising rate fpr, so you can use one setting disc thingy for n/a, one for boost

 

Your stock FPR has no adjustability and is very weak pressure wise. Also, it has no setting for when your engine needs fuel the most, Wide Open Throttle (WOT). This is the main reason the 4G94 engine bogs down heavily at low RPM and loses power at the top of the powerband, lack of fuel. Installing an aftermarket fuel rail and FPR increases the amount of available fuel and forces you injectors to shoot more fuel the higher your engine revs. Thats the beauty of adjustability, you can set it up to make sure your engine always has the right amount of fuel to make power. No more bogging. More fuel=more power.

 

Sweet, thanks! Makes total sense. Now you say aftermarket fuel rail helps - I'm assuming its becuase it has a larger bore, thus increasing the volume of available gas, correct?

 

ding ding ding! correct you are. basically, it allows for a small reserve of fuel to be stored right behind the injectors, available when you romp on it, so it removes or reduces throttle lag caused by lack of fuel

 

your right... im thinking of FMU not fpr

 

which FPR did you go with?

did you just go with OEM or what

YES! it does fit the OZ with some minor modification and works beautifully. $80 is much better than the $200+ that other shops charge for the big replacement unit. Its also very stealth if you get the silver one...
