injector ID

[nboost]

Just purchased a car and was curious on the injector size. Was told they were 009's but then again i was told a lot of things about the car that havent seemed to be right...
one side reads a d3181AA and the other side a 621031?
Any ideas? already looked on gnttype and nothing....

You might want to check the chip, some aftermarket chips state the injector size on the back of them.

I put your second number in the search box and came up with a list of threads with that number in it. I went to the second thread listed and got This thread

Thanks a lot for the help! Just curious, at what FP setting would you say a 009 would run out of its efficiancy?

Dictated by your chip....Most chips are set for a sweet spot with fuel pressure of 42-45 PSI.
