Looking for the Best Fuel Injectors for My 7.3L Powerstroke

I’m diving into some performance upgrades for my 7.3L Powerstroke diesel engine and I’ve been doing a lot of research on the best fuel injectors available. I’ve seen a ton of options out there, and it’s a bit overwhelming, so I thought I’d reach out to the community for some advice!

Why Upgrading Injectors?

I’m really aiming to enhance the performance of my truck. Better injectors mean more power, improved fuel efficiency, and potentially better throttle response. However, I also want to make sure that whatever I choose is reliable and complements the existing setup of my truck.

What I’ve Considered So Far

  • Brand Reputation: I’ve read mixed reviews about certain brands. Some people swear by SAC (Single Shot) injectors while others recommend MVP or Bosch. What has your experience been?
  • Flow Rates: I feel like understanding the right flow rate for my needs is crucial. I’m currently looking at injectors in the range of 160cc to 250cc but would love to hear your insights.
  • Durability vs. Performance: Balancing performance gains with reliability is important. I don’t want to sacrifice one for the other. Any recommendations on injectors that have proven durability?

Questions for the Community

  1. Which injectors have you had the best experience with, and why?
  2. Have you run into any issues with specific brands? If so, what did you experience?
  3. Where do you recommend purchasing these injectors—online or local retailers?

I’m really looking forward to hearing your thoughts and experiences! Any insights or recommendations would be appreciated as I’m eager to make an informed decision that will improve my truck’s performance.

I’ve had great luck with the 155cc Delphi injectors on my 7.3L. They provide excellent flow rates and have proven reliable in my builds.

That’s awesome! I’ve heard those injectors are perfect for both stock and mild performance upgrades. Have you noticed an increase in fuel efficiency?

Don’t forget about the 7.3L ARP nozzles. They have a good reputation for flow without sacrificing reliability. I’ve used them in high mileage engines, and they performed well.

That’s a solid choice! I’ve been considering them for a future upgrade. How do they compare in terms of performance against the Delphi injectors?

I prefer the 160/200cc injectors for more power. They really wake up the truck and are worth considering for anyone looking for a performance boost.

I’ve used 180cc injectors on my truck, and I can attest to their performance. Just keep in mind that they require a bit more tuning.

Ah, the tuning is crucial! I’ve found that the right tuning with good injectors can make a world of difference in performance.

I’m really curious about how the different nozzle sizes affect the overall horsepower. Anyone have any insights?

11

Great question! Generally, larger nozzles can provide more fuel, resulting in higher horsepower, but it can vary based on tuning and other modifications.

I have no idea how injectors work, to be honest. But I’m here for the ride! Can someone explain it in simple terms?

For the 7.3L Powerstroke, I’d recommend the Industrial Injection Super Phat Chops. They have great flow and increase performance. Just make sure to check your fuel system compatibility before install.

Installation can be tricky if you haven’t done it before. I found that using a valve cover removal tool really helps. Also, you might need to replace your O-rings and injector cups.

Adding a good quality oil and fuel additive can help reduce stiction significantly. I’ve had success with Rev-X oil additives myself.
