Injectors
 

I don't want to hijack the mpg thread. Lets start here. I want to run the 253 nozzels at about 2500 to 2600 psi. Any suggestions or experience?

Ya lets not screw up the mileage thread with injector talk.

What did he 253 nozzles come in? You mentioned the 293 nozzles came in the D24Tic, obviously those are bigger than the regular D24T injectors. I have heard you can use Mercedes diesel injector tips, any truth to that?

The complete number is DNO SD 293 Bosch # The last 3 numbers indicate nozzle tip size in mm. That one is what is used on the d24tic. I want to run the DNO SD 253. Stock is a DNO SD 193 for the us. All the injector have the same body just different nozzles and shims for the opening pressure.

Yes but I dont remember what motors or years I think the MB 603 or 604 motors from the early 90s. They used them in the GM injetors also dont have a clue as to the years. I think 6.2 early 90s?

Why the 253? Why not go to the 293? Bigger is better!

Anyone know the nozzle size for a 1.6 turbo diesel? I have access to those through work, I looked up the DNO part number but our system doesn't show anything. Most of our stuff is in 9 digit vw part numbers.

Easier to get the 253 from the GM performance guys. What are the vw guys using in the 1.6 tdi? I dont want to go too big at first (no I am not gay).

So the 253 is stock for the 6.5 or 6.2 I'm guessing? Most of the 1.6 guys that had injectors were using mercedes nozzles. I had heard of using the GM nozzles as well. The 1.6 is an IDI, like our D24. The TDI (1.9) is a different injector all together and they have their own aftermarket of nozzles and whatnot.

I think the MB nozzles are in low 200's

I'll have to search over on the vwdiesel site and see what MB nozzles they were using. There were some guys making pretty big power with them, but most were running a Giles pump.
