Sorry about the late reply...
Not sure about the fuel pump but its bigger than standard. its very loud but its in tank and i havent taken it out to check. Has got standard injectors...which i would say are highflowed for the power levels the car is producing.
The ECU is a Reytec (tomei computer) running a map flow sensor. Check out;

It has had the AC removed, however the climate control unit has been relocated to the center consol and is controlable etc.
