Hi Guys,

I am planning to go single turbo in the near future and my fuel system need to be up to par. My question is, are there any FPR that is a true bolt on. Bolting on to the stock fuel rail?

I'm trying to avoid tapping my fuel rail or having to relocate it on the firewall. Can I just add another FPR without yanking the stock one out? I did a search an alot of you are using Aeromotive, SX, or HKS regulators, can you use the AEM one.

The AEM unit is the only bolt on deal?. I know it's really a Honda thing but if will work on my 7 without alot of fuss. I'll use it.

Which fuel pump will work best as a drop in unit?

As far as injectors goes, I will have my 850s enlarged by RC to 1300s.

Please drop in your advice only if you have done such a mod to your car. I would be most helpful if you did the work yourself!

Thanks for your time, Jay

 

I just ordered the Aeromotive regulator from Summit Racing. The regulator is $130 (cheapest of the 3). As you mentioned I have heard many great things about them all but the Aeromotive is the cheapest. I went with that one. I'm using -6AN fittings so getting the right fittings was tricky. I can post them if you need them.

Also I am using RX-7.com's drop in pump. Its a snap to install. I have read that the Walbro is a better pump for alot less money. I think it takes alittle work to get it in there. Either one for you application should be fine.

Thanks that will be great. I forgot to mention that my car is a 3rd gen.

 

I got an Aeromotive FPR, too, except from Jeg's. I got two AN6 male-to-male flare fittings, one AN6 flare plug and three AN6 o-rings. The ports on the FPR are ports rather than flare fittings, but apparently flare fittings work as long as you add an o-ring. I asked around and this seems to be the normal practice for installing an FPR. I also wanted to avoid having to switch the whole system to stainless lines, so I got some 5/16" hose nipple to AN6 female flare fittings from http://www.pegasusautoracing.com/. They come in straight (about $5) and 90 degree (about $20 each) but I am not exactly sure what I'll need yet so I got two of each. I plan to install it on the inside of the driver's side fender in the return line. At first it will be in series with the stock regulator, but I plan to remove the stock regulator and install a 5/16" hose nipple in its place eventually. I'll have my fuel pressure gauge sender hooked to the 1/8 NPT port on the regulator, and it won't read correctly most of the time with the stock regulator in place, as I plan to run stock(ish) fuel pressure. I just got the regulator after a tuning shop told me the stock regulator fails (though I haven't heard of this before from owners) and noticing that the stock regulator does a lousy job of maintaining pressure (sometimes it is high, sometimes low).

I know that isn't quite what you are looking for, but it seemed like the easiest way to install one of the standard units, so that is what my plan is.

Can you just install one of these in the fuel return line, ie in series with the stock FPR? Is there any disadvantage to this?

 

Okey instead of just doing a fuel system upgrade it looks like I'm putting in my single turbo. You see, I had this nasty exhaust leak at my d/p. While I was trying to replace the d/p gasget. I manage to brake one of the stud.

 

Yes, you can just run them in series. Whichever regulator wants higher pressure wins. So, for instance if the stock regulator wants 52 psi and the aftermarket regulator wants 58 psi, the pressure will be 58 psi. The only downside to this that I am aware of is that you can't get a very reliable pressure reading from the gauge port on the second regulator -- you have to the have the pressure gauge before the first regulator. It may read correctly when the second regulator wants higher pressure, but it is way low if the first regulator in the line is the one that wants higher pressure.
