Injectors

I'm fairly new to the diesel community and I was wondering if someone could give me a good break down on injectors. I know the basic principal behind how they work for a diesel engine but I'm not sure about the upgrades that can be done. What is the difference between stage 1, stage 2, hybrids, and so on. Thank you for your help in advance.

Stage 1, 2, and 3 injectors vary depending on who makes them...

Typically Stage 1's will be 160cc stock nozzles or 140cc with 30-80% nozzles

Stage 2's will be 160-180cc with 30-100% nozzles

Stage 3's or hybrids will range from 200-250cc's with 30-200% nozzles

A few of the injector builders that come to mind are Beans, Swamps, Rosewood, and Casserly.

Their are more out there but those are the main builders.

Once you get into upgrading injectors a lot comes into play that determines how well they perform.

A stock turbo can't really handle much more fuel than stock. So one of the first things you'll have to address is upgrading the exhaust housing or even the entire turbo so that you drive pressures wont get out of hand.

Depending on which rods your truck came equipped with will determine how much fuel you will want to put in it. Some 01 and all 02-03 trucks came equipped with PMR's (powder metal rods) which will meet their limit at around the 400hp mark. Easily attainable with stage 2's and the correct supporting mods.

Another item to look out for is the HPOP. Our trucks don't have injection pumps so it relies on the HPOP to drive the injectors. If you have a weak HPOP it will really hinder the performance of the injectors. HPOP's can be modded and upgraded to support more fuel.

The stock SD fuel system sucks... So the deadhead system will have to be upgraded with a Regulated return. That will allow the trapped air to be sent back to the tank instead of going through your injectors.

And tuning will play a big role in performance with injectors too. If your truck came equipped with split-shot injectors and you go to single shots you will have to have tuning to make them work, and tuning to get the most out of them. Stock programming with say 160/80 split shots will run just like stock, but that can all be fixed with custom tuning.

Not necessarily,... You can get hybrids as small as 200cc which I wouldn't say is a massive amount of fuel. Massive fuel would be more like 400cc with 400% nozzles which in most cases are un-streetable.

Hybrid Injectors use 530 plunger and barrels which don't require as much ICP to make the same amount of injections pressure's. When you are running lots of fuel 3000psi with 530 p&b's will do a lot more than 3000psi with regular/stock p&b's because there is more surface area for the hydraulic system to work with.

So with injector nozzles that flow twice as much as a stock nozzle (100% nozzles) the 530 p&b's will allow you to get the injection pressures higher to better atomize the fuel and let it burn more efficiently.

I could explain it to you better if I went back and read up on it. Hopefully somebody else will chime in that can explain it better. But basically "Hybrid Injectors" are put together using injector parts from different model injectors.

im still not real sure exactly about injectors, but i just put a set of Swamps stage 1 single shots in my 99 and it runs awesome. granted, i do have a bully dog programmer, AFE cold air intake, banks wastegate, and tranny kit. i was skeptical but what i have works great with my other upgrades.
