What secondaries to run?

Greddy injectors are just Denso sold under a different name. They're all going to be low impedance, so source some 6-10 ohm, 10-20 watt resistors to go with them. I don't think Bosch makes 720cc injectors; I just know they make the 1600cc injectors that are popular on high HP builds.

Injector dynamics makes some 725cc high impedance injectors that are really nice and are based off a much newer injector design with adapters.
I just put a set in my primaries and a set of their 2200cc High Impedance injectors in my secondaries.

if you go with them make sure you ask for 11mm/60mm upper adapters and denso lower cushions. They should know what FCs run now because I just worked with them on mine.

Just installed a set of RC Engineering (www.rceng.com) 750cc injectors in the secondaries of my S5. In conjunction with a BNR Stage 1 hybrid, a Supra TT fuel pump and tuning with an S-AFC II, the best dyno run was 267 whp and 230 ft-lbs at ~9psi and 11+ AFR.
Their high impedence units are referred to as "Saturated".
From the FAQ on their web site:
"Do I need high or low resistance injectors for my application?
Injectors are classified into two categories.
1. High impedance/resistance (saturated) 12-16 Ohms.
2. Low impedance/resistance (peak & hold) 0.5-6 Ohms.
Saturated injectors require roughly 1-1.5 amps to open the injector. Peak & hold injectors initially needs about 4-6 amps, and once open drops to roughly 2-3 amps to keep it open. ECU design will dictate the use of one or the other. Most late model cars will use saturated injectors."
