So someone asked me a few weeks back which injector was the primary and which is the secondary, black or green (blue, whatever) and my reply was "I don't know, I don't pay attention because I always flow them". I'm working on a twin secondary injector TBI build at the moment and had two sets of black and green injectors, one set from the 87 flatty project car and one from a member on here whom shall remain un-named. The latter set were billed as being almost new 87-89 set with very few miles and they look it as the bodies are spotless and the plastic very clean and bright. Sadly they were both plugged almost solid, after working several solutions through them I finally got them working well again. I build an injector test rig because a lot of aftermarket injectors don't come with data, the kind of data important to a good running car using an aftermarket ECU like megasquirt, dead time, actual flow at various pulse widths and voltages and actual flow at very low pulse widths. Of course I got a big surprise part way through, I had a black top on the test rig and it was flowing every bit as much as the green top I'd just done. I finished testing all four before I entered all the data into a spreadsheet to get the actual flow rates: black #1 550 cc/min, black #2 932 cc/min, green #1 929 cc/min and green #2 1117 cc/min. Thanks to member Indiana who posted the answer to the puzzle, it was an H serial number injector from 84-85 that is interchangeable with the 86 injectors. http://www.starquest...showtopic=90896 Even stranger, the other injector was a J serial number 86 injector with a green top, I haven't dealt with many 86's but I thought they flowed less and were all black top. My 85.5 has two black tops in it. The injectors from the flatty were correct L and M code injectors. Moral of long winded story, get your injectors flowed! If you're running an MPI it's even more important as there is quite a bit of variation injector to injector.

I am in desperate need of working 86 OEM injectors. (I need to keep my California car basically stock for smog and collectible reasons.) The injectors don't have to be perfect, some leaking around the injector cap is okay, as long as the injector is not stuck open or beyond all hope. I am willing to pay a good amount of $$$ for some working injectors, thanks!
