I ordered these parts in order to get ready for boost, I think I'll be able to install them without issue but want to make sure that having these in won't affect the NA operation of my car.

I want to get as much stuff done before my car goes to the installer as possible. Trying to save some coin here.

It's the Honda/Acura FPR and the walbro 255lph fuel pump.

thanks guys

 

It would depend on where you set your fuel pressure. As for the fuel pump, How many more LPH is it vs stock? I figure the 02 sensor would see a rich mix and send that info to the computer to try to compensate by adjusting the fuel delivery etc. But a computer can only compensate so much...

 

As long as the fuel pressure is set to the stock you won't have a problem.

 

Anyone know how to set the fuel pressure on the AEM unit? I don't have it yet

 

There is a locknut on the adjusting screw. Loosen locknut, turn adjuster to change pressure with vacuum line disconnected and pinched. You need a pressure gauge attached to the rail to adjust. retightened locknut when done.

 

Whats the stock AEM pressure going to be?
Would it be set to a stock honda pressure to begin with? It's the universal honda/acura piece and I'm not sure if all of their cars don't run the same fuel pressure

 

If you don't have a pressure gauge. I wouldn't install it. A common problem on lessor honda's (civic and integra's) is that the stock FPR can't bypass enough fuel back to the tank when you stick in a big fuel pump. What happens is, the fuel pressure never returns to stock. I get the impression the '2k FPR has a higher flow capacity so, this isn't a problem. The AEM FPR comes with several orifices internally so, you can tune it for the fuel pump. If you find the fuel pressure won't return to stock then you have to install a bigger one to bypass more fuel to the tank.

As long as the fuel pressure is stock, a large fuel pump won't affect anything.

I think the ''2k is 4 PSI higher than a GSR/Civic SI. Don't quote me, I haven't looked it up recently. It's in the manual. Always measure with the vacum line disconnected from the FPR.

 

who knows what the regulator will be set at from AEM, the ones I've seen always need to be set, as the locknut is loose. Stock pressure is 47-54psi with the vacuum hose disconnected and pinched off.

 

AEM claim they are set to stock (47-54psi static) but it's not the sort of thing you just trust. Mind you, getting a gauge on the rail involves some work.

The generic AEM has an NPT port on it to attach a gauge but not the Honda/Acura one. Found this out myself on the weekend.
