Best Injectors
I am looking to do injectors and a turbo upgrades, as of now I am leaning toward the kc38r turbo and just don't know quite enough about injectors to make a decision. I am not looking to make crazy horsepower (below 500)
Asking about size not necessarily brands
Truck is stock besides
4in straight pipe
6637 intake
Hydra with php tunes
Boost, trans, egt gauge
Trans was rebuilt using a little heavier than stock components along with heavier torque converter

Just for fun factor, 160/100 should do fine. Should put out 400 RWHP. Mitt need 38R to go with it and cold air intake as well. Get new tunes for your hydra. Should have forged rods. If your not towing to much, 200/100 or 238/100 will work well to. If you want to stay closer to stock, 160 stock nozzles. Make sure the truck is 100 percent. That means all your sensors, up pipes and everything are in good shape. U-joints as well. All filters should be changed as well.

I just called my rep that I purchase all of my new injectors through and he tells me that he knows nothing about Alliant stopping production.
That being said, we specialize in Reman 7.3 injectors, we own tons of core sets that we can remanufacture for you, or we can rebuild your set specifically from your truck. Converting them from an AD to a 160/80 is no problem at all.
Please shoot me an email or give me a call when the time is right and we will do our best to get you set up.
Thanks

Also should the turbo come before injectors or other way around? If I do one I will do the other just not right away,

Depends how big your going on injectors.160/30 I wouldn't think so. Bigger then that it mitt smoke a lot. And your tunes should also go on what turbo you have also.
Dave Merritt, what is the difference between the 160/80 and really the 175/80? Same cores and just different inters, or something more drastic?

I quoted the information from David Merritt in relation to the rumor that Alliant may be stopping production of new 7.3 injectors. Although, I will take my best shot to answer your question and if someone with much more knowledge disagrees, I welcome their thoughts.
The first number (160 or 175) is the amount of fuel in cc's that is standard on that size injector. Then the nozzle (80 or 30 or 0) is the amount of overage that the injector can handle when being pushed. So, when looking at a 160/30 vs a 160/80 injector, the 80 can deal with more fuel demand in a way that keeps the FIPW down and EGT's more under control.
This is how I understand it, but I might be a bit off.
On a personal level, I plan to get 160/80 because I want near stock daily driving with a bit more grunt when towing up a grade with EGT's near or under 1000.

That is what I was trying to get to, but the thoughts in my brain were not getting out. I do this all the time, just ask my wife about the stupid crap we bicker about...

When I was looking at injectors I talked to PIS and said 160/30's would be perfect for staying around in the mid 300 to right around 400 hp. When it's time for injectors PIS is who I will be going with I would talk to an injector builder of your choice and tell them what you want as far as HP.

I have PIS 160/30s. I wish I had gone with 160/100's but as far as a boost in performance, it was very noticeable even when I was running the stock turbo with just the WW gen 1. When I bumped up to the 38R things got even better. The 30/80/100, etc. refers to the holes in the nozzles and how much, in percentage, they are oversized from stock.

Sous, I know all that but if you go onto the sites I was wondering if the body of the injector was different from 160 to 175. Meaning, is it a AA or what ever model. I don't believe I see a 175 from alliance. Nozzles I know about. That's why I asked Dave if he would pop back in. God bless,
