I keep reading these threads and they can be confuseing. If I were to buy new fuel injectors would they come with new nozzles as a unit ? Or are they sold separate. I can't understand why anyone would buy a new injector without a new nozzle. Will someone please explain.

 

If you buy new injectors they will have new nozzles. I think where you might be confused is where you buy new injectors but then you buy new aftermarket nozzles (ie 50 horse aftermarket nozzles). Hope this helps

 

to expound on the original question, can you buy aftermarket nozzles, ie bigger nozzles and put them on your stock injectors and essentially have a set of rebuilt injectors?

 

Yes you can buy larger aftermarket nozzles and put them on your stock injector bodies. But they will not be essentially rebuilt since the internal components have not been touched. You would need to take your injectors in and get them balanced and tested if you put larger nozzles on so you can make sure the pop rates are the same. Or at least in my opinion that's what i would do.

 

That's exactly what I did with my injection system. I bought the nozzles, sent them and my original injectors to a well trusted diesel shop. They swapped nozzles, set pop pressure, and supplied sealing hardware. I was able to save about $150 by doing it this way. I only suggest doing it this way if you have a trusted diesel shop to take them to. Otherwise full body injectors from a seidel performance place is the better option.

 

thanks for that clarification, because that is what I was thinking of doing, and yes I have a couple of good shops around.

 

If you go with nozzles just make sure you get the pop tested correctly.

 

by the time you buy a set of nozzles send them out with your stock injectors have them pop tested etc you can a buy a new set ready to rock and not be down waiting for them to come back.

 

I saved $150 doing it the way I did, sending the new nozzles and old injectors away. Pulled the injectors after work, had them sent out the next morning, and had them back that afternoon. Put the injectors back in and I was done in 24 hours. Granted I did get to use a empty bay at my shop, and take my work truck home. My 65's ended up costing me less than $300 all said and done, including new sealing hardware.

 

That"s what i did on my jammer 2's that i had. It cost me 250 bucks total to buy and to get the nozzles put on and pop tested. So i thought that was purty cheap
