Adjustable Fuel Regulator?

I have a turbo Voyager and I am going to be increasing my boost soon and I know I am going to need more fuel. Does anyone have any suggestions on what type/brand of adjustable fuel regulator I should run?

Thanks in advance!

There are a few TD guys making adjustable fuel pressure regulators from stock units, which work very well.
Local to us in Calgary, Alberta is James Richardson who makes a nice one for not too much money $30 or $40 dollars.

You can find his email on either the SDAC list, under local clubs (for Calgary) or I believe it is still posted on Gary D's site under the turbo - fuel section.

Also the Holley adjustable unit for the 87' Grand National works/fits perfectly and is adjustable from 35psi-65psi.

I have tried the Holley unit that is for the GN and 3.8 ford. That one plugs right in but i couldn't adjust it past 45. The store took it back no problem. I thought it adjustable to 60. I now am using the Accufab brand sold by FWD performance and Forward Motion.
The part # is BREG and is used for the '86 to '87 GN. It works great. Easier to do up the bottom bolt too on this one.
It is available at most places. I paid 163 CAN at a local shop. Same price as FWD Performance 120 US $.
taxes extra.

BTW you might now want to do a AFPR off the bat. i mean you will be increasing full preasure across the board. and you really dont need more ful at idle.you dotn need more fuel at 3PSi or 8PSI.. you need it when your stock injectors and full supply system and computer cant provide more. like over 14PSI... you dont really need more fuel before then because the stock system in working order is more than capable to supply fuel to that point.. your problem arises when you go over 14PSI...

now a AFPR wworking with a FMU and larger injectors will do just about anythign your sick twisted mind can come up with..

It all depends on what your performance target is going to be. What are you shooting for?

I am going to be installing the Grainger valve next. I am not looking to drag the van at all. I still want it to be an everyday driver. With that being said, do I really need an adjustable? Or should I just get larger injectors?

why do you feel the need for bigger injectors? what is your goal? bigger injectors will increase the fuel deliver across the board just like a AFPR. you dont need any more fuel untill over 14PSI. seriously, install the grainger and do a decent exhuast and put on a IC. you should be more than happy with its speed..go faster in steeps.with just that you should be making alittle over 200HP flywheel..




are you planing on running more than 14PSI?
once you have 14PSI (which you dont need any aftermarket fuel managment), and a intercooler you wil be AMAZED how fast it is.. and how much you need traction. take things in steps. try 14PSI witha intercooler first. i mean you dont want to step from stock boost to over 16 or so PSI at once..
once you are bored with what you van can do without additional fuel being supplied then you can decide what sort of additional fuel supply you want..my suggestion for simply idiot proof and wire and forget ability it to wired in secondary injectors witha preasure switch . each one should give you 2 or so extra PSI of boost with a good A/f ratio. two of them will put you up around 19-20PSI and that is just about all you really will want wtith the small mistu...
then again just my .02$.. that is what i have done to my normal everyday van: a probe IC, 2 extra injectors and 19PSI. 3 inch exhuast.. very very quick. and almost no traction untill after 45MPH..

be careful with the holley grand national regulator i had 1 on my lancer till i went to the track last ran 20psi boost and it blew out the diaphram in the regulator leaking and blowing off the vacumn line to the regulator shooting fuel onto the intake and wrecking my 3 bar map not too reliable i think

The only reason I thought that I might need an AFR is my A/F guage seems to run a lot more in the orange/red then in the green. It seems to be fine when I am around 10 PSI or higher, but while cruising it fluctuates a lot, but seems to be more on the lean side. Does that sound right?

That is exactly what you want. If it were to stop fluctuating at cruise (whitch can happen if you add too much fuel) you would kill your gas mileage and ruin your piston rings quickly. The A/F guage is only used at full throttle. You want it to be in the correct range at boost and ignore it any other time.

Just in case it's not understood, "correct range" while under boost is rich, about 0.87V - 0.9V on the O2 sensor (9 lights). Anything less and you run the risk of melting or cracking pistons.

Typically a stock fuel system is good for about 16 psi on an otherwise stock engine.

Thanks for the clarification. I thought that the A/F gauge was supposed to be used at all times. So, if I am in the green or close to it while under heavy throttle, then I am good to go. Thanks for saving me the trouble and extra money of trying to install an AFR.

Now it's time to get that Grainger valve in!
