I have a 1981TD and was wondering whats the largest nozzle possible I can put to get the most power? I heard VW nozzles work as well as some truck nozzles? True?

check the diesel performance section- it's a subforum of the diesel discussion.

Thanks... I did a search and some people are saying the 265 is the way to go. I'll ask over there

There are no larger nozzles. Because of MB's unique prechamber design, other injectors do not have the correct spray pattern to work without melting things. You will have to get custom nozzles or hone out stock 240 or 265 ones.

I started asking around and found a guy who has a bunch of nozzles that he'd be willing to get rid of. A lot of 261's.
Do the 261's give more power than the 240's?
I'm thinking of buying them up if anyone else wants in.
