Will the two stage injectors from the aaz work with the standard jx pump. They are 150bars so in theory they should work just fine, and are quieter..?

Same question here, will a 2 stage injector do its work efficiently with a JX dieselpump meant for 1 stage injectors?
Does the JX pump(cam plate) need an upgrade to run the two stage injectors  ?, Has anyone done this?

As I understand it, injectors are matched to the cam plate in the pump. If the pump had dual stage cam plate then you need dual stage injectors. I believe the cam plate ramp has a step in it to initiate the first stage then ramps up for the second stage.
Sticking a JX pump on a AAZ with JX injectors seems to give the best results but leaves you with a lack of adjustment on the LDA. LDA can be tweaked and twiddled a little.

Is it possible to modify a JX pump to run the 2-stage injectors? Are cam plates for JX and AAZ/1Z interchangeable? If they are , do you need to modify other components of the JX pump?

Why?

Is it possible to give a correct answer to the question: "Why?" ?
The main answer would be to give it a try.
Why?
Everybody is converting AAZ pumps with JX covers, isn't it possible to convert a JX pump with an AAZ cam plate?
 
Why go for a modified AAZ pump if you can modify your JX pump? (if it is technically possible)
