I have done A lot of research on this and have spoken to various people so i thought i would put a thread up for some help. Basically we all know we struggle with the hdi injector upgrades. Most know im struggling getting some injector nozzles for my M-tdi build. I have some vw ones sitting here that are
DSLA 150P 357
now the dsla refers to the orifice size the P stands for needle type. in this case 4mm and the first three numbers are the spray angle.
landrover ones im currently running are DSLA 145p 355 so the same size and needle type as the hdi nozzles just the incorrect spray angle
hdi ones are DSLA p142 1474
So my theroy is that the hdi nozzles will fit directly onto the 300 tdi injectors. Which they do. i have tried. however due to just wanting to get it fired up i was unsure as they came off a higher pressure injection system.
im not after a Fast motor Atm just a good increase from standard and safe for now untill i get chance to go further.
I also know the plane angle of the hdi but cant put it to any use as i have nothing to compare it against in order to match up anything. This is where i require some help. I would like someone to explain cone angle and spray angle to me in a little depth. with drawings/diagrams if possible.
the maths involved to compare the injectors against my engine
And last but not least the Dam plane angle of the vw ahu engine. because for love nor money i cant find it.
any help will be appreciated however small and hopefully we can get some stuff up on this forum that will help further understand in the future for others.
