I will add P.I.S. to that list also. Since the company was sold to Gray's Diesel they are off my Christmas list!

 

Surprised someone mentioned to stay away from Swamps? I've never heard anything but good about their injectors on the net or otherwise. I know Brian at BTS talked highly of them - this was a few years ago though. They have probably been doing it longer than anyone.

 

ANY REBUILT injector is hit and miss as no rebuild is a remanufacture. I would trust only NEW Alliant ! If you want to modify, start with NEW Alliant injectors and an aftermarket outfit that you trust to thoroughly bench test flow and balance.

 

That would get pretty darn pricey really quick. It would almost be paying twice for injectors. Rosewood has the rep he does for a reason. But yes, for me, I am happy with my power levels. It would only be new Alliants if/when I have to get new ones. Until then, I will shim and do o-rings first.

 

And on the other hand @Tugly , last I recall, recommends Full Force.

 

Yes... Ryan Casserly at Full Force diesel is my guy. No matter who you choose, you are dealing with small parts with a lot of wear. Rebuilding is not remanufacturing - it's the art and science of salvaging all you can and replacing what you must. All this while making a reliable affordable product and a living at the same time. It's not just who does the best, a few are on par with each other. What matters is when things don't go as planned, does the rebuilder have your back? I can thunder out a most resounding "Yup".

I opted out of used, not because anything Ryan said or did... but because my injectors had a 1/4 million miles on them and they were not likely to be as robust after a rebuild. I wanted at least 300K miles out of my next sticks with proper care and feeding - and I didn't believe installing used parts would get me there.

I'm one of the very few people that tried rebuilds, then yanked 'em and put in new. I'm here to tell you... there is a difference. There was no difference in performance, it was the sound - they sound "new-ish". Snappy. It's not unlike getting that new car smell when you don't buy used - it's an intangible benefit, but there it is.

Meanwhile, back at the wallet... it's a hit to go new - but so is doing this more than once in the lifetime of your rig. Who's to say we can still get new on the next round? What if all that's left are injectors with one or two rebuilds in their jaded past? If I am ever forced into that situation (which I doubt the truck will survive that long), I'd use my pristine cores.

 

 

If I am reading this correctly, this company sells NEW Alliant injectors with bigger nozzles installed.

7-3fordInjectors

Wish I had found this before I bought mine from UDP. Not that mine are bad, but new is always better than reman.

 

I won't waste the space to quote Tugly but a lot of my reasoning is the same. I've read it in other threads and to sum up what Tugly said...buy once, cry once. While my sticks might have put me one PMS mod too far I do not regret the path I chose. Are new more expensive...yes. With all of the issues I had (and currently have) I have had zero product issues directly attributed to to the physical injectors. You are already making an investment and new was the only option for me. I don't like potentially spending every weekend with the valve covers off.

AFAIK all the reputable vendors we discuss around here all use Alliant injectors for their new products (stock or modified). One of the reasons I chose my injectors is that the only modification was the nozzle. Other than that they were brand new Alliant AC code injectors.

 

This has been my exact experience but I have been dealing with it for several years now. I purchased mine from UDP so "lifetime warranty". He has sent me 18 injectors because none have idled correctly. This last set has been okay, but in the winter I get a code just like you said above. I havent had time to dig into it, but wish I would have gone with new vs rebuilt.

 

If their prices of new AD Alliant injectors is in line with their listed prices of new AC Alliant injectors, they would be my go to place for purchasing when the time comes. Of course I would hit up RiffRaff to see if they wanted to price match because I prefer to do business with Clay, but cannot ignore a good discount on the same parts. Hopefully though, I will not ever need injectors, we will see...

Ya, sounds like a nightmare. No matter how good you get at removing valve covers and injectors, it is still a pain in the *** and knuckle busting. You sir have my sympathy and admiration.

 

Thats a great find, and are the cheapest price I've seen on new AC.

 

 

How have I not seen these prices before... I need to refocus my Google-Fu...
