Ron, thanks for the response and taking the liberty of replying, I
always welcome technical/experience based replies.

In addition to the summit fuel rail, Bahn Brenner shows one on their
site, just click 'fuel systems' then click 'fuel rails'.  Nice picture
of the rail and another pic of it mounted on a 16V intake.

Benny and I have done almost parallel installs - we built them together
but implemented them
separately.  He's farther along than I am right now, but both cars are
running.  See my answers
below - pardon me for my liberty in answering a question you asked of
Ben.

> while it seems like a great system however, the learning curve and the

Moderate, I'd say.
  
> VW fuel pumps, relay, lines to the engine, etc are acceptable.
Lines to engine *bay* - a FPR has to be plumbed in.  FWIW, the lines are
8mm, which is essentially
equal to 5/16" (almost on the nose) for conversion to more popular line
sizes.

> VW temp sensors are also acceptable.
Yup, with a slight mod to the code.  Simple utilities exist to re-flash
with updated info
regarding the sensor you use.  Easy.

> The stock ignition (from CIS-E), knock sensor, etc are also
acceptable.
Yup.

> RPM signal is easy to get too.
Yup.

> The stock VW fast idle circuit is acceptable.
Nope, MS uses only an on/off FIDLE signal, so stock (as applied to
Sciroccos idle air bypass
valve.

> The fuel rail on the 16V seems to be one of the largest expenses; no
one
> seems to have an adaptation from another VW product that works.
Yup.

> Injectors fall next in line after the rail.
Used ones can be had very cheaply.

> Now for some questions;
> Are you running a wide band O2?
Neither Ben nor I are running WB yet...it's definitely on the list,
though.

> What did you do for a fuel rail; I have heard that a 1.8t lines up
> however it requires extensions?
Had one fabbed by a friend locally.  My advice: swallow hard and get the
Ross rail.

> What did you use for injectors?
I used ones from a Jetta 1.8T, these are plastic and thinner than the
Digi-style, which is a
pretty universal form factor in the injector world.  Damn near any
injector it seems is physically
compatible with a Corrado-style digi injector.  Just pick high- or
low-impedance and your flow
rate...

> Do you wish you stayed with Motronic? 
I never had it.  I certainly don't miss K-jet or KE-Jet.  This is way
more fun, and really, the
whole point of the project.

> How many miles do you have on the system?
About 10, around the block many times!  Need an air filter solution and
some non-Megasquirt stuff
sorted before I go on a true journey, do massive datalogging, etc.

HTH
