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?

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).

Well, the D24T is the rabbit's engine with 2 more cylinders, so, they use the same injector nozzles, and exist two or three part numbers for the same injectors. From what I read in vwdiesel.net they use the "GTD" or MB injector nozzles as performance injectors, and some VW diesel parts site, sell the 6 "performance" nozzles kits for the D24T.

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.
