So I took these out to sell them, and a guy asked me if they needed to be cleaned or not..
Since my #2 cylinder just went out, and I have not yet found the reason, I couldn't honestly sell them to him and tell him not to clean them. I didn't feel like spending $100 some dollars to get them tested and cleaned, so I decided to flow test them myself.
I turned on my fuel pump via AEM EMS, and connected the battery to my MR2 while it was running to get constant voltage. I used a hacked injector harness a la Gavster and connected it to 12v one at a time, for exactly 60 seconds, spraying into a bottle of which I marked where 740CC was with a sharpie. They all came out within 5% of each other, which I think is pretty decent. Here are some pics of the process.
These are Nismo 740 CC injectors BTW, that are up for sale
Injectors
3 1/8th cup ~ 740 CC
Filled the slimmest bottle I could find, and made a reference mark.
The Setup::
Peekaboo
Engine bay with injectors in place.
Set the fuel pump output in AEM to stay on
The system was connected to my running MR2 so that I could get constant voltage across the fuel pump.
Fuel pressure was a tad below 50 PSI for the whole duration of the tests.
Testing:
Results:
After, I referenced 755CC and 770CC on the bottle to get an idea about how much more was being sprayed. I wish I would have done it before, but from the pics you can tell that it isnt much higher than the 770cc mark.
Just thought I would share!!

Oh, and if anyone tries this based on my thread, make SURE you don't make ANY electrical connections anywhere near the injectors
