Well, as a start I'll give you some answers pertinent to VW nozzles.

The stock early 1.6/1.6 TD (DN0SD293) nozzles are not the hot tip for performance with .7mm lift. They got a little better with the DN0SD293 (later hydraulic lifter nozzle) at .72mm lift.

You'll find that a lot of nozzles fall into this general area. Some are better, some are worse. GTD nozzles are definitely a step up at .81mm and the 1.9TD nozzles aren't far behind at .8mm but the pintle is where you see the major difference.

Notice the distinct difference in the shape of the pintle. This will mean there is additional fuel at the tip of the injector resulting in fuel being delivered more quickly and reducing the injection interval. I've come across pintle lift up to about 1mm.

I may be wrong on this, but as I recall from threads of old. People have experimneted with shiming the pintle for more lift. This was back before we had acsess to GTD nozzles. What I recall with this though is that they could get between .2mm and .5mm extra lift! This leads me to believe that the lift is not nearly as important as the size and shape of the nozzle as the lift can be modified.

On the Chevy nozzles - I do not have them to test. Would you happen to have any pictures of them? I'm curious to see what the pintle looks like as well as what the diameter is of the orifice.

I'm doing this because I am interested and I want to know as much as the rest of you. But, for me to continue to do this I have to look out for my own best interests. If that is so difficult for you to see then I'm sorry we could not coexist here and I will be sad to see your insightful posts journey elsewhere.

I totally understand what you guys are both saying but you guys are taking this way to personally. This just an internet site. You guys are killing yourself over nothing. Im not all for advertising either but does it really bother you that much? I think you guys need to go modify an injector pump or go take a rip in your wonderful yet evil turbo diesels.

That is a one big ass nozzle, I would think that this would be too much fueling, but hey try it out and let us know man!

Is this a 0º nozzle or is different cone angle? Almost looks like a 12 degree test stand nozzle.

Edit: Nevermind, I just read the whole post. :oops:

I don't have them here in PG, I belive that they are still at Dave's shop in Aldergrove. So if he has a moment or two mabey he could pull one apart and take pictures of it. They are 0 degree as well.
