Fuel Pressure Regulator which one?

[Sideways s12]

Hey guys need a suggestion on a Fpr which one is everyone using? I hear the nismo one for the sr works is this true and how much do they run. Thx.

[DALAZ_68]

nismo fpr type A...

[Sideways s12]

Where's a good place to buy it and about how much do they run?

[sjbsuperman1425]

thenismoshop.com thats the cheapest

[Sideways s12]

Ok so I checked them out but I didn't see anything about a gauge I take it the gauge is seperate also what do you think about an inline fpr?

[sjbsuperman1425]

the nismo one is just simple. buy that, buy a $30 gauge and then build a "T" from stuff at your local hardware store.

[Sideways s12]

I can get a gauge from the same place correct?

[domicubarican]

Im using a SARD fpr, works fine for me.

[Sideways s12]

How much? Does it come with a gauge?

[domicubarican]

I dont remember how much, I got it from a local garage guy I go to for parts. Well yes and no, technically they dont come with a gauge and my guy gave me one for free. Only thing bout it is that its in bar and not psi. I havent had any problems with it especially with my supra fuel pump.

[Sideways s12]

Ok thanks

I can't keep a consistent base pressure with my SARD, don't buy it.

I've heard from a lot of ppl, that most aftermarket FPR's can be problematic. You hardly ever hear about anything like that with OEM FPR's.

[domicubarican]

I've heard that SARD's are rising rate fpr's and not static like the nismo (I think that's the correct terminology). Is that true?

Where can I find an oem adjustable fpr I'm gonna be running 1000cc injectors and I'm gonna need one

I'd set the FPR to 36.3psi (pump relay jumped), then 2 days later, check by jumping the relay and the pressure would be off.

There's two different models. I'm running a SARD and it is most assuredly the static device. Very reliable fuel pressure, makes it easy to dial in the fuel curves.

Is the lock nut backing off the adjuster screw?

[bersh240]

my sard is perfecttt. no issues at all

[Sideways s12]

So sard is good? Only the static?

[Buddyworm]

^Yup, only the static rate. I've heard there's a few knockoffs floating around so be careful of who you buy from.

If I have modest power goals and a Walbro 255 fuel pump, do I need to get an aftermarket fuel pressure regulator? I had a cheap one from eBay, and it's crapped out on me.

[bersh240]

yes. the stock fpr will almost always fail when using an upgraded fuel pump.

[s1390]

Has anyone had any experience with the AEM FPR?

Good question, I have the FPR mounted to the strut tower, I applied enough pressure to the locking nut, I think... I've set it and locked it too many times, I don't trust the part and it'll be replaced.

Thoughts on the Megan FPR? Seems like a reasonable price at $75 and it has a gauge. This is from FRSport, so I'd imagine it could be had for cheaper elsewhere.

A buddy of mine ran a Walbro 255 with his stock FPR and had no issues. I've got a Walbro too but hearing all you Nico guys say the stock FPR craps out with a Walbro does scare me about trusting my stock FPR.

[float_6969]

The stock regulator doesn't crap out with a walbro. The opening inside is too small, and at idle, and low loads, can't bypass enough fuel back to the tank and the fuel pressure goes up and the car runs too rich. Not terribly rich, but enough to cause a little rough idle, etc.

Any idea if the Megan FPR is worth purchasing?

When I replaced my stock pump with a Walbro 255 lph high-pressure unit, it ran rich ALL the time.

Nismo FPR solved the problem.

[float_6969]

Ahh, mine just ran rich as I described till I replaced the FPR.

As for the Megan, I have no experience with it, so I can't say anything about it.

[biosehnsucht]

Was yours the 255lph high pressure or "normal" ? I remember there being two models of 255lph Walbro pumps.
