Re: Fuel injector Part Numbers
Was thinking that, presumably the Denso are OEM?
I have found service kits

Re: Fuel injector Part Numbers
Follow up question...
Anyone know what voltage the injectors need to open?

Re: Fuel injector questions
Did find something on rx8.Com suggesting
yellow P2/Secondary injectors:
Flow Rates:
450cc/min at 3 bar
486cc/min at 3.5 bar
524cc/min at 4 bar
Resistance: 11.8-16.5 Ohms
Voltage: 8-15 Volts, Nominal 13.5 Volts
Amperage: 1.0 Amps
Pressure: Min. 36 PSI (2.5 bar), Max. 101 PSI (7 bar)
Any reason to expect reds need a different voltage?

Re: Fuel injector questions
There all 12 v dc mate.
Ive checked injectors at home with a injector plug connected to 12v.
A bit of piping and a syringe to create pressure...i used cataclean as fluid and was clearly able to see that my injectors were creating a nice spray pattern and although no flow data they all looked the same flowing so as there was not an odd 1 out they were deem good... my misfire was found elsewhere.
