My bad...I confused the term. 
How difficult would it be to convert the system to a return type fuel system?
To make sure I understand this correctly, the FPR used to be mounted on the fuel rail right? This made it possible to upgrade to something like a Comptech FPR, right? Also, because of this change, PY aftermarket fuel rails are incompatible.
From what has been posted on the Temple of VTEC forum, the MY06 S2000 and Civic Si have both a MAF and MAP sensor. This is something that is apparently kicking Comptech's butt, which is why they haven't been able to complete the supercharger for the MY06 Civic Si yet. Apparently they are going to use some sort of piggy-back system, but that isn't going to resolve all the issues. They MAY be working with Hondata to resolve whatever the other issue(s) is(are).

The Vortech is blue, and ther Comptech is red.
The 00-05 cars have a non adjustable regulator on the fuel rail. The FMU's install in the return side of the regulator and efffectively close the return to increase fuel pressure in boost.
The 06 Civic Si uses both MAP and MAF sensors. MAP measure pressure, and MAF measures air flow into the engine.
An additional injector controller running Aux injectors will probably be they way most companies work around the returnless fuel systems.

sorrry, no MAF on the 06 S2k
If that is the case then there is one less problem to worry about. I believe Comptech is struggling with the MAF/MAP issue on the Civic Si.

The 06 has a returnless fuel system. The fuel pressure regulator is in the tank.
To use a FMU (like both Comptech and Vortech SC's) you need a return type fuel system. As the FMU installs on the return line to increase fuel pressure in boost to add fuel.
There isn't a MAF sensor on the 06, but there is a MAP sensor.
Hiding boost from the stock PCM is what Comptech does with the ESM and Vortech does with 1 of there black boxes. It's known as a MAP clamp. Which blocks a boost signal from the MAP sensor from going to the PCM.

Would an inline fuel pump, like a Walbro, be a partial solution?
you need a return type fuel system

With a returnless fuel system I am assuming that the ECU regulates the amount of fuel being delivered to the rail. My guess is that is does this by regulating the amount of fuel that the pump pushes. So there is probably a piggy-back required to adjust the voltage to the fuel pump to supply extra fuel. Or it possibley could be a valve on the new pump that purges the extra fuel before it even enters the pump, but again you'd need a control to regulate the amount of fuel being released before the pump Again this is all speculation on my part since I have not looked at the 2006 fuel system.
