No I am meaning only CR nozzles, reason is I used and sold Injectors from a very reputable company with good results on performance but got some issues.
We examined a set of those special built injectors.
Conclusion was shocking, on one injector only 4 holes of 5 were machined.
I will add some pictures hoping they show up
The upper hole is round shaped aka left original only the other 4 EDM eroded

Sprayangel up to 2,5degrees off

Not one hole was what you would call round.
due the different holes it is a miracle the piston was not molten.
In the future I try using unmodified Bosch parts like the Cummins Pegasus (Qhyd 1000) with sprayangle 72,5° -->100% more volume 6 sprayholes
What I believe is that some of the molten pistons are coming from bad machined nozzles.
I will try it first with the original 2004-7 pistons knowing to have the wrong sprayangle but having an excellent spraypattern and plenty of volume.
We must test first if a sac type nozzle works on a standard injector who uses the micro-blind nozzles. But if it is possible there is a great range of nozzles we can use.
