Stock Injector Specs?

I am wondering what the stock injector specs are? High Ohm or Low Ohm and what flow rate at what psi... anybody have an idea?

Thanks,

Chris

S 356-404 cc's/min (yellow)
resistance on all injectors should be approximately 13.8 Ohms at 68 degrees F.

Correct me if i'm wrong. I believe there are 4 units of intake manifold injectors (yellow) & 2 units of rotor housing injectors (red) . Altogether 6 injectors in high-power Renesis.

Forgive me if my question is sound a bit stupid. When we start/crank the engine, does the fuel injected through all the injectors or just the direct injection? What about while the engine is idle? If there's any link that shows how the High-power Renesis works when starting/cranking , idling & revving .... that would help a lot.

If they weren't working, you would not be able to drive it *at all*.

As I stated in this thread:

"The RX-8 "hi-power" has 6 fuel injectors, 3 per rotor, that are designated primary, secondary and primary 2. The primary injectors are 290cc and the secondary and primary 2 injectors are 380cc.
These injectors are staged in various levels and configurations based on load and RPM, which is quite different from any piston engine.
The primary injectors are responsible for most of the fuel delivery at part throttle and completely for idle. They are usually run out to maximum output by 3500 RPM and WOT.
The secondary injectors are responsible for much of the fuel delivery under load beyond 4800 RPM, but are seldom driven beyond 60% of their capacity.
The primary 2 injectors are brought online around 6250 RPM and are not driven beyond 35% or so."
