Ok so.. THIS is what I get for trying to follow in some cool footsteps on a build and get stuck having to buy something I otherwise wouldn't have needed. As luck would have it, I get an AEM fuel rail along with a filter conversion/relocation that will not work with my stock FPR. So I have no option but to upgrade. I've been researching for the last couple hours and find a good deal of crap, mixed with the usual bias, sprinkled with elitism.. What info I found leads me to 3 possible options...

1- AEM regulator. This is suggested mostly because it's a shoo-in fitmentwise, but, I read lots of diaphragm issues caused this little piggy to **** the bed. Has AEM done anything to fix this over the last 9 years? Is it legitimately a good option now?

2- Blox regulator. Priced between the AEM and Aeromotive, there were mixed reviews on this one and not many good, detailed failure reports; most just stated "had it for x time and it crapped out on me." I also know Blox indeed HAS come a good way in the last decade.

3- Aeromotive regulator. A bit more costly and certainly a good track record of quality. This is also a unit that generally doesn't see much service below 700hp. So I would be killing a mouse with a shotgun making this choice. If it is TRULY worth it and I'm not just going overkill, I'm not opposed to grabbing one.

Solid input please, personal experience is always a plus.
Thanks all!

 

 

have a part# or anything I may be able to reference?
I think Blox and the Aeromotive offer 1:1 for boost. Not sure about the aem.

 

 

 

sweet, thanks for that! I'd need to inquire about the AEM rail compatibility. I'm also wanting to go berserk with converting my fuel lines to the AN braided. *shrug*

 

 

it does but my stock regulator won't fit. If it were offset, no problem, but my flange is not offset.

 

 

yeah, I have some options for a regulator. Narrowed to the 3 more popular choices. I didn't think about Holley though, only actually saw it in a handful of mentions.

 

 

 

750cc injectors

 

Funny you say that, because, the fact it's a Civic is the reason I never thought Holley. Lol!!

 

I have a direct fit Honda Holley FPR on my supercharged car. I have used it for over ten years... I had an AEM FPR for the first 60 miles of my engine build... the diaphragm split and dumped raw fuel into the intake manifold damaging the engine. I would never use an AEM FPR for a boosted application.

The EK factory FPR will work with the fuel rail that you have... if you choose to use a stock one.

 

Good to know the EK one will fit. I was going to ask if you had thought about using the Golden Eagle part that turns the FPR 90-degrees? http://www.goldeneaglemfg.com/index....roducts_id=231

 

Aeromotive never look back. Its what I have and its rock solid reliable always. Sub 700 builds have them all the time. Definitely not overkill, just quality. Yes you'll have to remote mount it but generally pretty easy.




AEM quality is sub par from my experience, electronics or otherwise. And I don't really like the style of regulator that mounts to the fuel rail because it limits what size line you can run (only 1/8th port on the AEM rail IIRC)

 

96-00 Y series regulators have offset holes (so does the GSR and S2000 if I remember correctly) if you are wanting to just keep a OEM regulator (or get one for pennies on the dollar in comparison).

The most common reg. used here is Aeromotive off rail.

Golden Eagle rotators are for center port regulators.

The only issue I've ever experienced with AEM regulators is the inability to work on high pressure apps (ie. 2 fuel pumps)...as in I've had one work perfectly fine on a single pump, swapped to 2 pumps and the regulator may as well not have even been there. Took that regulator off and put it on another single pump build, worked perfectly fine. (The 2 pump car received a bolt in Aeromotive, which is also offset hole, #13115)

 

Only reason I'm looking away from stock is my end goal is 500-600whp. I'm on par with everything so far except Injectors and the CSS block. I wanted to grab my turbo kit as well, but still only received about 1/3 of what was due to me from Uncle Sam.. I'm piecing together what I can until that happens or tax return, whichever occurs first.


Good insight! I was thinking Aeromotive or Blox (looks like Blox has followed Aero's footsteps there).

The stock is always an option as I go to the junkyard fairly often, usually once a month anyways, but as I mentioned earlier; ultimately I'm building to surpass stock capabilities this round so I'm looking to bigger n better!

I look toward the AEM for simplicity installing. That's about it. On paper, It should do ok for my goal, just drumming up some new insight. You're a builder as well and I'll definitely take your insight into consideration on this!

 

^^^Co-Sign. Been on the Same Aeromotive for 13 years. Never worried, never looked back, never bothered about all that nonsense. And I was well under 500whp at the time. Y'all play too many games gettin' cheap.

 

Its not like they're that expensive either.

 

Well I am one of those who suffered from a aem diaphragm failing and hydrolocking my engine. Im not aware of a resolution. I have a automotive now that I upgraded my lines but I had been using a b&m regulator that fits into a modified oem for 2 years with no issues

 

So looks like installing the Aeromotive will be simple enough, I'll just need another plug for the regulator port on the fuel rail. I suppose I can put in a call to AEM to get that part number.

 

You can call, but you're not out of luck if you don't get an answer that is acceptable to you. (I doubt if they remember, anyway). Get that port measured at a fittings shop or McMaster. Measure and solve. Then you KNOW what you have for certain. It's not exotic, it's just AEM. They rebadge a LOT of stuff that was never initially their design.

 

I think I saw a package of the hardware you get with a new rail on the AEM site. It **should** contain the grub screw that is used to plug the gauge/accessory port that's not in use. Aeromotive will require a separate purchase for the gauge since it doesn't come with one.. I can install the gauge in that particular port on the rail and just use that screw that came with the rail to close the regulator port..
methinks I've solved my dilemma. Lol

Found the info. It's 1/8 NPT, by the way.
