Ok so as my turbo project comes closer and closer to completion, I am wondering what kind of fuel set-up I sould run.

I am probaly going to end up getting a T3 Super 60 Turbo.

Now I know a lot of this has been covered, but I am trying to get everything together so...

How much MAX boost can I run on a well-done fuel set-up, dyno-tuned...without running into problems?

How much would you recommend for a turbo set-up without any fuel upgrades?

Right now I have a VAFC2, would my stock injectors do enough for about 6-8 PSI? Or would I have to upgrade the injectors?

Or should I just sell the VAFC2 and get a Greddy Profec E? Is it worth the money?

Or should I just get a FMU?

Should I replace the injectors? Or should I do a return fuel system?

Lol, so many options...I need help!

You will be fine at 8 PSI on stock injectors. You can convert to a return-style fuel system or run an inline pump and fmu. How serious are you? If you are really serious and want to fully build the block then wait for the AEM EMS. If you just want something quick to help you get boosted I recommend the GReddy e-Manage. It is inexpensive and allows you to retard ignition timing, which is very valuable with forced induction. Plus, if you like the Profec e-01 it can be used in conjuntion with the e-Manage.

AEM EMS is going to be a super nice piece. Self teaching and all, but WAY overpriced! GReddy E-Manage is a solid piece for the price. Quite powerful and functional for the cost.

Just remember our stock injectors are tuned from Honda @ a 85% duty cycle. Any additonal strain on these will be bad for them.

i remember reading that
so if that's the case i still dont understand what the SF kit is doing
just adding an inline pump?

The pump is there to supply the increase in FP from the FMU.....

Who makes the pump? Walbro? How many lph?

it's a nice thought but someting bound to happen on a car that was factory turbo'd

i plan on gettin a walboro in the future but not in any rush at the moment
same thing with injectors. I'll b fine with 5 daily until i get some internals.
i wann get another engine but i know i cant have that sitting in my parents garage..maybe one of my frineds thou
they alrady got plenty of **** just lying around

so what are all the options for fuel tuning. Ive got most of the other stuff planned out for my kit, but fuel is by far the most confusing. For a custom set-up what can be used, and how can you tune it?
edit: what does the vortech FMU? I know it increases fuel pressure, but what else is needed to run it?

You will need an inline fuel pump to deliver more fuel.

^so the vortech controls the flow of fuel, and the fuel pump actually delivers it? IS it possible to tune both of these without any other components?

I heard that the ignition timing function was having trouble working on our cars? is this true? anyone running the emange using the ignition timing?

the vortech is hooked up to a vaccuum line.........it reads boost pressure. There are different types of ratios............8:1, 10:1 and 12:1.

For every 1 psi of boost the inline pump will increase fuel pressure by 10 psi or whatever the ratio of ur fmu is.

i highly suggest converting to a return set up..........u will need a fuel pump, fpr, and you will need to modify ur fuel rail. Stock injectors will be fine if u stay under 10psi.
Also, your vafc2 will work fine but you will definitely need to get it dyno tuned ASAP.

^^ahh i gotcha...that seems like a pretty efficient set-up, except if you're pump breaks . So what is wrong with the inline pump set-up? More stress on the stock injectors? We need an aftermarket fuel rail that allows a return line, and injectors. So why is a return line better?
