First, good luck finding a manifold w/o the DFI. I've
tried. Second, how much is the FP ECM? How much is
the Wide-band O2 sensor? The batch fire version with
the wide-band O2 is $2000 and the sequential version
is $2700!
Here's the part number for the Accel superram intake:
N/A. That's what my accel catalog says.
None of this means anything if you have $10000 to
spend on your injection.
How much do you want to spend?

p.s. if you want to mix and match, buy the accel
single-plane intake. It comes with rails pre-machined
and the bosses are cast and machined into the intake
(and you can buy it separately for $450 from jegs and
summit). Then you get the injectors, harness,
computer, etc that you want. With your setup, the
single-plane will prolly be a better choice for
upper-RPM flow. Maybe not.
