How to indentify stock injectors ?

[looks slow]

I recently got ahold of a 97 s14. I was the 2nd owner of the car after it was wrecked so the guy i got it from wasnt able to tell me much about what it had and what it didnt have. This is what I found installed on the car : Walbro fuel pump, greedy E-Manage, rising rate FPR, t3t4 turbo ( unknown trims ) the car was claimed to have been running 8 pounds of boost befor it was totaled. With all the other stuff I discovered, and the claim that it was running 8 psi, im skeptical as to weither these are factory injectors. Is there an easy way to tell ? ive got the fuel rail off, and i cant tell any thing just by looking at them.. no idntifying lables. Any pointers ?

P.S. Don't tell me that stock injectors are red... this means nothing. Tomei 550s and 740s are red... :coolugh:
