2.5tdi V6 nozzels ? headache!!!!

Audi a4 avant 2.5tdi V6 quatrro

Hi guys,
I've had a look about the interweb as I'm planning on doing a couple of mods to my a4 avant over the next year or so , which include full turbo back exhaust (no boxes or cats) , FMIC/SMIC (not decided which yet) , and larger injector nozzels, remap.

The bit I'm stuck with are the nozzels I have a bosh part number for larger ones which isn't a problem and I can get hold of fairly easy but I've heard I can also get the larger nozzels off of some iveco trucks and cummins engines but never seen a mention of which truck models or year ??? Can anyone tell me which have compatible nozzels or know of anyone who has got them off one of the trucks or should I just get the bosh ones I have the part number for ?

This is the part number I have for the nozzels I'm after


DSLA 142P1519

Thanks

Thank you swarcup there is a lot of useful info there , that's were I found the part number for the nozzels but I couldn't find any info on there of which iveco or cummins models or years to get the injectors off of

Cheers mate I must have overlooked that somehow , I just had a very quick look for those and they are more expensive than the bosh ones with that part number I put up earlier so that rules the cummins out then just the iveco left . What I do know is that I read somewhere that they need to be off an iveco with the vp44 fuel pump like mine so maybe a phone call to iveco to see if they could tell me which models and years had that pump ??
