Hi everybody

Want to ask about the adjustment of 2-stage injectors.
I will change my nozzles(DN 0SD308) with GTD nozzles(DN 0SD 274).
QuickTD told my that there is no problem to put these nozzles in my 2 spring bodies injectors.
And what is best adjustment for these modificated injectors.
On the body of my injectors write - 150bars.....
But the factory value of GTD injectors(RA/SB intercooled engine) is 155-163bars.I have added an intercooler!
Is the higher value better - I think it is :roll: what is your opinion??

In connection with this, I want to mention that my friend own Citroen Xantia(I think it`s not very popular car there) with 1.9IDI motor with factory intercooler and BOSCH pump.The Injectors look just like mine(AAZ MK3),but the car produces 90hp factory!!
And the injectors work at 175bars!?!? So more bars - more horse power or....

:roll: :?:
I`ll be happy to hear some opinions...

What is the specific year and model of the Citroen and what country are you in? We did get some Citroens a very long time ago but they are not currently selling them here.

I can't tell you much about the nozzles, but I can tell you it shares a cam plate with the VW 1.9 IDI.
