I was hoping to find a set of used injectors to test, rebuild if nessesary. I have access to equiptment to test them. I finally found a pick and pull in my area. They have a few well picked over mercedes. no 5 cylinder NA diesels. All 6 cylinder. How would I determine if any of the injectors I came accross would work? If I was looking to upgrade, is there any alternatives to stock?

I could test and rebuild mine but can't afford the down time. I just want to swap them out and go.

It doesn't matter if you know what you're doing, as long as you look like you know what you're doing.

If you get ones from another Engine that is the same as yours you will have less trouble when it comes time to set the Pop/Opening Pressure.

Being that you have access to the proper equipment I do not see why you could Pull the Injectors from your Engine and rebuild them.
I know that puts a little more stress time wise on the rebuilding process.

You might contact C Sean Watts concerning which Injectors bodies can be swapped from Engine to Engine.

You could cross reference the serial numbers on the injectors.
If you have a bosch injector shop, ask them if a ##### part number injector is suitable for your MB 602na
