sweetPSI

hey boys!

i have a potentially *retarded* question to ask...

i need a FPR, but i dont know which one to go with...

i have a OBD1 ZC with a 14b turbo... im running 7 psi...

...the problem is the only fuel management i have is a greddy blue box (fuel management unit) and a set of H22 injectors... im running a stock fuel pump and stock FPR... stupid as hell i know...

ne way im getting a type-r fuel pump (i hope thats enough...) and im looking for a really good FPR without spending a fortune... any suggestions?

i was looking at B&M but its only a partial FPR as it hooks up to part of the stock FPR, am i right? furthermore, its not boost-sensitive as far as i know....

WHAT SHOULD I GO WITH? IM SO LOST! i know next to nothing about fuel pressure regulators...

let me know guys PLZ!

first off hi and welcome

then... the type R fuel pump offers no advantage, other than being newer... what you need is a Prelude pump off ebay, cuz they sell really cheap on the bay... or you can get a Walbro for abotu $80 USD

next... what kinda FPR do you want?? you want a boost dependent one? then go with a FMU disk of about 10:1 from Vortech or something. Since you have a Greddy blue box, that should be sufficient fueling in itself and you do not need an FMU (cuz the two systems do the same job differently, so you'd really be dumping a lot of fuel in there for no reason - the systems are not 'smart' and would not know what the other is doing). So I submit that you do not need any sort of FPR unless you notice a problem... if you want a really good FPR though, you can get an Aeromotive unit, or an AEM one. I'm pretty sure both require an aftermarket fuel rail and bigger lines, but I'm not 100% sure. Turbod16.com can offer much help as well.

Im with Bruno, deffinately no gains I see with the Type R Fuel Pump.
Get the Walbro from our tcc vendor Amar aka astroboy.
$150 canadian shipped I believe is what he sells them at.

I've seen many ppl blow up their turbo motors, from leaning out.
I say do yourself the favor and spend a little bit of $$$ and get the boost sensative regulator.
atleast you will have the piece of mind knowing your motor wont lean out. And no worries for boost SPIKE!!!

I wouldn't boost or have a boosted vehicle without having the proper FPR on it.

It happend to one of my cousins, didn't want to listen to get the FPR and his motor in his 323 blew up!

djtrini, it's stated that she's got a Greddy blue box, and as far as I know, that takes care of the fueling... no need for an FPR.

imported_djtrini

heheh I know Bruno, she got the blue box from me actually

the FPR to me is a good investment, as you never know if your going to want to run higher boost later on.
And then you will deffinately need one, if your running more than stock boost levels (think its over 10 psi)
Greddy blue box is good up to 10PSI.
On the Greddy kit that box comes with, its supplied with 310cc injectors as well. So she should be ok with those Prelude injectors.

I wouldn't feel safe without a FPR on a turbo set up, even with the blue box. Boost spike can cause some serious damage.

I have read that an FPR is basically a waste. As long as you have a good fuel pump (walboro) and good tuning with big enough injectors you should be fine.

Spend the cash on a walboro from astroboy and then save a bit to get a good engine/fuel management setup like hondata or uberdata or AEM EMS. IF you want to run reliably you have to spend the cash.

Another option is.

As long as you get a fuel pump to supply enough fuel to the injectors. You could have your ECU chipped using Crome, which will allow you to have proper fuel tunning for the larger injectors, from idle to redline for both vacuum and up to 10 psi of boost with the stock map sensor or more psi with a different map sensor.

Also, using turboedit your ingition timing can be adjusted properly for boost so that it is retarding like 1 degree per psi.

One last thing, the benifits to this are. you have basically a stock setup...no "black boxes" that are sort of a band aid solution. These "black boxes" are usually very tempermental to changes in weather. I know my turbo Escort GT with 330 injectors, APEX S-AFC, Cartech FPR and 255 ltr/hr pump, is senstive to weather changes. Basically with a proper tune you can have a car that runs like a factory turbo car with lots of power and good emissions.

ok guys,

so supposing i get a walbro pump and see how that works before i even consider a FPR, what size should i get?

i hear a 255lph (or whatever the units are...) would be sufficient...

any other suggestions or ideas?

ok, she's asking about an FPR, and you guys assume she'll be comfortable chipping the car herself with CROME or Turboedit. That's the stupidest suggestions I've heard yet.

the 345 prelude injectors, a Walbro 255 and the blue box will be enough for 7 psi safely.

when you are ready for more, and have some paper in your pockets, come back for further advice.

imported_FlatBlack

How is it stupid? I didnt say she should do it herself...I said have it chipped.

Im offering her another option, cuz a chipped car with a proper tune will run way better and cleaner then just using a FPR.

edit *how dare you suggest to charge for something you have no rights to!!?? you didn't write the software, so what makes you think you have the right to charge ppl for it's use?? ppl like you make me sick* - bbarbulo

If she is running OBD1 then go with uberdata or hondata. Like Bruno said some bigger injectors, a walboro in-tank fuel pump and the greddy blue box should be good for now although it wont be working as well as it would with a proper dyno/street tune.

NickB, if she doesn't know what a FPR is, how do you expect her to bust out a chip and her laptop and write a new bin for her ECU??? She can't have it chipped b/c that software is not commercial. All of those programs are self-use, no one should be chipping it for her. That's the whole point of it... is to learn to do it yourself. And if anyone charges her to do it, he should have his typing fingers broken.

She already has all the parts she needs except for the fuel pump, so don't complicate things for her.

I'm boosted.. and I upgraded to a DOHC VTEC fuel pump. If you're still running a stock Civic pump it's a good idea to swap it out. civics got 79lph pumps while DOHC VTECs got 135lph pumps

check out this link from Hondata...

You don't want to raise your FPR too much... you want bigger injectors instead... the stock DOHC VTEC supports pretty good hp at low psi... 55psi and under (stock setting ususally 40-50psi depending on motor) support 300 flywheel hp.

BTW.. if you're running H22 injectors (280cc) instead of the orig 240cc injectors on stock maps... you're already running rich... and if you raise the fuel pressure say goodbye to your o2 sensor and cat

See next post...

1c6_eh6_t-si

to be exact...

Prelude H22 VTEC
92-96 345CC (Peak and Hold)
97+ 280CC (Saturated)

Civic/Integ SOHC VTEC, DOHC VTEC - 240CC (Saturated)
Civic fp 42-46psi (hose off)
GSR - 48-55psi (hose off)

I don't know if the ZC is peak/hold or saturate... i'm assuming saturate... cuz if you through 345CC injectors in place of 240CC without any fuel management... your car wouldn't even idle cuz it's so rich.
