Are there any differences in these? Better worse? What about TD nozzles in an N/A?

1.6 Td injectors have a higher breaking pressure (150 psi I think) compared to NA injectors. You have to fiddle with the timing to use 1,6TDs on a NA

I was also wondering about the difference between these injectors. I am running the 1.6 TD pump and injectors on my 1.9 TD AAZ. Can the AAZ injectors (028 130201 B) be used with the 1.6 IP?

1.6NA= 130bar, 1.6TD =155bar

Just clarifying so the yungies don't get confused.

NA34X mercedes benz Turbo injectors are 155bar as well and flow more fuel than the "upgraded" 1.6TD injectors that have GTD nozzles...

Thanks for the replies. Was just wondering if that part number was one of those AAZ two stage injectors. Interesting information about the Mercedes injectors. Always interested to know how to get more fuel into the cylinders.

i'm not sure but i know you could also try vanagon or quantum nozzles, they are supposed to flow more than stock as well

Thanks Sethyboy85. Limited quanities on hand huh? then soon have none lol: I have been buying my parts from AutohausAZ for a long time now. Their heat shields are about 85 cent each. They really do have the best prices.

Oh yeah they are slightly shorter but it's nothing the injector lines can't handle after you take off the brace that holds them all together then put it back on after installing the lines.

Then they might be a perfect fit for an AAZ using 1.6 TD lines and IP. I had to remove the clamps and bend mine up slight (#3 & #4 mainly) to make them work. I am a little worried about the lines being stressed. Thanks for that last tidbit of info. I have a new plan :twisted:

Where can i find just replacement nozzles for these? I can get the injectors from 2 audi 5cyl diesels and i know they will need to be rebuilt.

hillfolk'r · « **Reply #13 on:** January 13, 2007, 09:20:23 pm »

try not to bend lines ,its not a good idea...
the(zinc?) plating can fracture on the inside of the lines when you bend them,and over time that junk gets sent into your injectors....
repeat after me: I will never bend hi pressure diesel fuel injector lines :wink:

sethyboy85 · « **Reply #14 on:** January 13, 2007, 09:25:15 pm »

thats why you have to take the brace off and install one injector line at a time to get the angle correct then reinstall brace.
