They wont sell you nozzles by themselves. You either buy new Bosch, remans or send them yours but your not guaranteed to get your exact ones back all the time.
Since when do you no or get yours back. They track every serial number that comes into their shop.

If yours don't test good or can't be repaired they send you good remans instead. It's happened to several people and it says it on their website.

I understand that. You implied they may switch up others injectors with the ones that you sent in.

I didn't imply anything.
That's exactly what they do if yours are completely trashed. If yours are good then they send them back. Sorry if some didn't catch that.

Wouldn't a normal person send in the whole injector to get them balanced together? If you say all your injectors are fine, and just going to slap nozzles on, why not spend a couple hundred extra and have them install the nozzles and balance?

If you are worried about them finding a bad apple, then how do you think slapping on nozzles is going to turn out? Point being, if you're 100%+ the injectors are fine, why be worried about exergy finding a bad one.

Because it's a lot more than a couple hundred more.
~$400 with shipping for extrude hone vs ~$1500 + shipping with extra insurance.
Exergy won't install other nozzles or even theirs without doing all the cleaning, baseline tests, and then the balancing, assy/dis-assy, and so on. Each step with an appropriate charge.
This is obviously the right way to do it if you got the cash.
I'm looking at other options. Originally I was just going to jam the stock ones back in as is then decided a little bigger wouldn't hurt.
I never ever said I was worried about them finding a bad one. That's their job. I had mine tested and I'm confident the shop did their job.
It's all the other costs associated with their procedure I'm trying to avoid right now. Trucks been down for two years and I'm trying to get things going and putting money elsewhere at the same time.

No worries, iv installed just nozzles on trucks not the whole injector with NO issues!!!


I have even swapped 2 sets of 100% nozzles even and never had an issue.

The thing I have always wondered is what happens when the injectors have 10-20000 miles. Are all of them going to still be balanced evenly? Seems like no matter what you have a couple that wear quicker. This is where I think it depends on the power lever. We all know we have seen trucks where only a couple injectors got replaced but it still runs fine.

Whats the difference when you spend buku money on exergys and they get 20k miles on them.. Still think they are perfectly balanced....? Unfortunately, we have no control over how hard parts wear.

Honestly I would be more concerned with having a failure with an injector stuck open than being balanced. When they are out things like smoke at idle when there never used to be are indications to check balance rates. A stuck injector doesn't give much notice and wrecks stuff fast.

:happy: surprised this isn't a big one in the regrets thread.
Yah I plan on doing a lot myself things that many say don't attempt like transmission build but injectors no. When the time comes for injectors the only thing I will do is the R&R the rest will be left to Exergy.

I think the only regret most have it seems it's not going bigger the first time around.:D
FWIW now that I think about it I've heard of more issues with stock injectors and really high PW than people that don't balance the injectors after changing nozzles but that's just me.

I've went both the Extrude Hone route with 60% over nozzles and Exergy 80% over injectors, both worked fine. That said, I'll be going with Exergy again to do the whole injector when I go 100% over this time.

Call this number and ask for Jim. Kenametal Extrude hone is the business name.
(724) 539-5000

Does Jim have a last name because whoever answered the phone there couldn't find anyone to direct me to named Jim. Or a department would be helpful also.
