common rail injectors
i have a question, any and all suggestons would be greatly appreciated. i have a 2003 cummins with 111,000 miles. its runs like a scalded dog, and i have no problems. i have all the necessary upgrades to support running 100 horse injectors, and my question is..... what is the deciding factor between just nozzles and whole injectors? i heard somewhere that just nozzles are great for lower mileage but once you get to about 100,000 miles its better to just replace the whole injector to keep from dealin with the injectors leaking. AND if thats the case why couldnt i buy nozzles and a seperate injector rebuild kit. i would appreciate any input because the difference between nozzles and whole injectors is around 2300 dollars and if its an avoidable expense i could do a few other upgrades without havin to save for so long. thank guys and gals.

*wildbill took care of er for ya!!
Way I understand it is they are real touchy to very small particles. Easiest way is to send them in, have them rebuilt, then they can bench/balance test them. So when you have them reinstalled, idle will be much smoother/quieter. But one problem to rebuilt injectors, how long are they going to last?? Read some went a year, some went only a few months, or some didn't get very many miles before they let go. If that does happen, possible engine damage (round $10k worth). Something to think about.

If you have anymore questions, feel free to ask/search around. We got a lot of knowledge lurking around the site.

i was thinkin bout rebuilding them myself. i just didnt know if there was a kit for that or if i was SOL. see, ive been looking and studying both and i was gonna get them both tested locally before installing, but i didnt want to buy nozzles and my injector bodies be wore out, and i didnt want to buy whole injectors for whole lotta money if i could save some by DIY a rebuild for my injector bodies with nozzles.

do you have any programmers or chips on your truck?? Programmers like Smarty claim to add 230 HP, you can do great things with electronics and most people stop there because of the cost of the common rail injector i would just go with nozzles and make sure they are installed and pop tested by a very knowledgeable fuel shop and you shouldnt have no problems with them lasting...at least til you want to go bigger

Unless you know what your doing, have an injector shop do it. They can tell when one is junk as compared to good enough to rebuild. Most charge $1200ish to have them reworked. I mean it's up to you, but to be safe in the long run, I'd have em sent in. Tell you the truth, IDK what one looks like tore apart, just what they look like on the outside.
