So im not too familiar with injector lingo but I just need a bit of guidance and info that i couldn't find too easily.

Got a fuel rail with injectors for a relatively good deal so i assumed there would be issues.

First i compared the injectors. All say python up top and a number/letter under the JECS in the middle. Question number one, B-4-L-0 were the numbers or letters under the JECS...should they all be different or the same.. Question number two, I noticed B injector was missing the smaller o-ring, is this an issue, or are these easily acquired? Question number three is, the lower portion of injector 0 has brown plastic, while the other three match black, issue, or normal? All in question is pictured below. Thanks in advance.



Injector B



Injector 0




Sending off to be tested asap.

 

do they all have numbers dremeled on the back?
most likely deathworks, they redrill other injectors thats why some are different. orings are easly aquired, think napa sells a set of all the orings

 

They all have letters or numbers, b,4,l,0 were whats inscribed between the four.
Thanks.

 

You didn't tell me they were re-drilled stock injectors. I wouldn't touch those with a ten foot pole. If you're smart you'd get rid of them.

 

So i shouldnt even get them flow tested? three look like the holes are perfect, the fourth has an offset hole from the rest...

 

Hey i had somewhat of the same issue. I had bought some injectors from the dreaded craigslist and wasn't sure if they were what he said they were so I went to Boost Lab and got them checked out and cleaned. Luckily they were legit. If you need info on Boost Lab here is the web address- www.the boostlab.com- Kirk is a great guy and I will definately do business with him again. It is better to be safer than sorry, so I spent a little money for reassurence.

 

yeah, if those are stock injectors by Deatchwerks do something else. Deatchwerks does good work do not get me wrong, but i would only use newer model stuff like the 350/370 guys use them and dont have issues. your injectors are 20 years old.. toss them. you could get a nice top mount rail and top feed precision injectors for a pretty good price and call it cheap insurance.

 

There is 525cc sti injectors on nasioc.com forums for 132 shipped right now. Those are your best bet.

 

scrap injectors asap

 

you can also get dsm 440cc injectors pretty cheap.
