Please educate me about RS4 fueling: what's needed?
<center><img src="http://pictureposter.audiworld.com/66538/tint_1.jpg"></center><p>I have k04 turbos, with stock everything else.
I am planning on getting the fuel system up to proper spec, and then getting a chip.
What do I need to know about RS4 fueling (injectors, fuel rail, fuel pump)? What's the minimum required? What's recommended?
The RS4 fuel rail is not necessary, right? I'll just need spacers for the injectors, right?
What about injectors? Any cheaper alternatives to RS4 injectors? Same question about the fuel pump.
I guess I'm looking for an efficient way to get more potential out of my turbos, but I'm not sure what a proper way is. Please enlighten me or direct me somewhere where I can learn about this.
PS: this is for an A6 2.7T, but I figured the S4/RS4 forum knows more about this stuff.

You may be able to study with SSP 245, "AUDI RS4 Design and function Self-study programme 245"
a self-study booklet on Audi RS4. it describes modifications needed for RS4.
you can get it through some car catalogue sellers.

Injectors, spacers(APR or AMS), and code to optimise them(APR, AMS, MTM, or tweaked X). You'll
need a corresponding MAF/hose combo based on what code you run. There are a good many other injector options as well as fueling kits from AWE, Vast etc... big question is if you want a kit or are going homebrew.

You can do chip+fueling but not fueling without chip...
most people either do a full kit (AWE, APR) or do a Stage 2 chip (X, AMS) and homebrew fueling (MAF+injectors). Since you already have K04s you could go either way.

i'd just get a fueling kit from AWE.
if you really want to do it yourself.. i'd go with rs4 injectors with adaptors to fit the s4 fuel rail, TCD, rs4 maf and airbox (from piggie-see my sig) and an X-chip .. run about 20 psi , it should run really strong. aixgelo78 had rs4 maf and injectors , evo intake with an x chip/Tcd (not tweaked) and put down about 350Whp.
