Thanks for coming to 1023 Diesel!

This the most common question we get on phone calls. 

"What injectors will get me to X Power goal doing X with my truck"

It can be hard to write down with so many options, brands, and options.


The Formula:

Fuel = Power
Turbo = Drivability
Tuning = The bond that ties it all together

What I mean by that, 

Fuel: You can not make power without fuel. No matter the goal, choosing the injectors/Injection Pump that gets you to the power level you want is the first step before anything else. 

Turbo: Fuel without air is not power. Its black smoke leaving the tailpipe with no actual gains. But the idea that "Bigger is better" does not work in most situations and certainly does not work when choosing a turbo. 

Turbo choice is key to maintaining drivability. We typically recommend running the smallest turbo possible that will still efficiently make use of the fuel (power) you are trying to make. 

Tuning: Tuning.. the most widely misunderstood and miss-used component to every build. 

Tuning is only as good as the health of your truck and the parts you decide to use for the build. If you pick big slobbery injectors and a stock turbo, it is unlikely your tuner will be able to make the truck run well for the goals you have set. 


Understanding Injector Sizes

What Do the Numbers Mean?
Most times, injectors are referred to in "160/30" or "250/100" format. 

First Number"160" or "250" is stating the injectors CC size.
aka. 160cc of fuel is available as a maximum quantity over 1,000 injection events.

Second Number =  "30" or "100" refers to the injectors in Percentage(%) OVER the stock size. 

So, the example of "160/30" = 160cc Injector with a 30% over the stock nozzle. 


A-Code vs Hybrids?

The Next thing you will see most often is "A-Code" or "Hybrid" injectors. 

Put simply, here is what that means: 

A-Code = 7:1 Injection Ratio injector
Most important distinction:
1. These injectors use 7x the quantity of oil to inject X quantity of fuel. 
2. Fuel pressure leaving the nozzle is 7x that os your Injection Control Pressure (ICP)
Example: 3000PSI of ICP = 21,000PSI of Fuel Pressure out the nozzle

Hybrids = 5:1 Injection Ratio
Most important distinction:
1. These injectors use 5x the quantity of oil to inject X quantity of fuel. 
2. Fuel pressure leaving the nozzle is 5x that os your Injection Control Pressure (ICP)
Example: 3000PSI of ICP = 15,000PSI of Fuel Pressure out the nozzle


What Size Injector Is best for me?

This chart shows the most common injector sizes, what ranges for power they are best in and where they are least efficient.
7.3 Powerstroke Best injector Size - 400hp, 350hp, 450hp, 500hp, 550hp, 600hp, hybrids

If you have a power goal in mind, this is an easy chart to go by!

Simply line up your power goal you would like with the most "yellow" possible. 

Will I need an HPOP? (High Pressure Oil Pump) 
Not all injectors are created equally, and A-Code injectors are far more oil-hungry than hybrids are. 

However.. this is purely capacity based. 

Stage 1 & Stage 1.5 Injectors (160/0 - 180/30) will be fine to drop in on any year 7.3 Powerstroke but in a race tune with high pulse width, will likely not sustain ICP.

200-205cc Hybrid injectors generally do not require an HPOP upgrade.

238-250cc Hybrid injectors do generally require an upgraded HPOP for max potential. However, this not needed in most tow tunes daily tunes and street tunes.

My recommendation is to click on the links below and read the descriptions of the injectors you are interested in. These will tell you what size require and HPOP and which do not!

BONUS! When purchasing injectors from 1023 Diesel, you will receive 60% off our in house custom tuning for your PHP Hydra, SCT, Edge Revolver!
