1) Are these injectors stock?

2) What PSI/Bar should they be at?

3) Any other thoughts?



1 -Injectors:

Siemens Deka

1054

1521390



2- What pressure/flow?

When I was researching these, saw one place that said R50 is 3bar and R53 3.5bar. What should my R53 have

What should be the flow on an OEM injector?



3-

See the mangled O-ring on Injector 1?

The FI cleaning Co said they could do what ever PSI/Bar I tell them and are willing to do a pre-cleaning assessment/test so I know what the car has been happening with.





More on this situation:



Pulled these injectors from my 2002 R53 mini (3rd ? owner 225k mi) and sending them to these folks to solve a DTC code (I forget now which one just know that FI was the next step, lean code?...forget because it was last year I rant this car last) that wasn’t solved with the usual Catalytic replacement https://highperformanceinjectors.com...eaning-process who were suggested in this thread https://www.northamericanmotoring.co...e-related.html



I am not sure what the POs did. When I did the Timing chain chasing an oil leak the prior one was off a tooth so I’m not expecting anything in here to be stock https://www.northamericanmotoring.co...oem-marks.html



Thanks in advance for your help.

 

Yes oem but idk what your looking fir but your looking far too in depth into the injectors if your thinking they're your issue... hook up a data logger like inpa and see exactly what's going on with the engine and sensors and everything. Don't just guess because you'll be guessing fir ever or atleast until your broke and totally frustrated.
you want some guaranteed good, stock injectors? You can have mine , shoot me an offer..I'm upping to 440s anyways.
the stockers are still on my engine now but can remove on the drop of a dime.

 

inpa looks cool. is thre a tutorial on here what to get an how to use it?

 

the INPA cables I have seen seem to work for R56 but none (so far) for R53.

 

I use mine all the time on my r53 and on others to help them locally. Go read the discussion going on about it rite now ,there's a guy who will even help you set it up on your pc fir you... but don't just assume though man , inpa works for alot of bmw stuff, I even just used it on my brother x3 too..best 25$ you can spend...it literally will display every sensors n how it's functioning and cylinder tends, fuel pressure per injector ect.. it's really in depth and will tell you pretty much anything you need to know going on with your car.
don't be scared to use the search button in the top right either, there's endless information on here all peeps gotta do is hit that search button..not saying yiu but I see the same questions constantly when they could be answered with a simple search on here or even google.

well, I did send in the injectors and they tested to specifications 330cc@3bar 440cc@3.5bar.....$60 of validation

I am going down the INPA road. received my cable and am awaiting on user "shrevemini" to feel better to do the remote install..... looking forward to seeing all that INPA can tell me.
