Seeking Advice on 7.3 Idi vs 7.3 Powerstroke

I’ve been diving deep into the world of Ford diesel engines, particularly focusing on the 7.3 IDI and 7.3 Powerstroke. I’m looking for some insights and experiences from those who have worked with or owned these engines. Here are some specific areas I’m curious about:

Performance Comparisons

  • How do these engines stack up in terms of horsepower and torque?
  • Is there a noticeable difference in acceleration or towing capacity?

Reliability Issues

  • Which engine tends to have fewer problems over the years?
  • Are there common issues I’ve got to watch out for, particularly with the IDI?

Maintenance Requirements

  • What are the maintenance costs for each engine type?
  • Are there significant differences in how often each engine requires servicing?

Fuel Economy

  • Has anyone tracked the fuel economy of both engines under similar conditions?
  • Is there a clear winner when it comes to long-distance driving?

Personal Experiences

  • I’d love to hear personal stories of either engine. What do you love or hate about them?
  • If you’ve switched from one to the other, what influenced your decision?

Looking forward to hearing your thoughts and any advice you might have!

I’ve driven both engines, and the 7.3 Powerstroke is definitely more powerful with higher horsepower and torque. The IDI is simpler to work on but lags in performance and fuel efficiency.

3

That’s true! I’ve found that the IDI can be really reliable and easier for DIYers, but if you want hauling power, the Powerstroke is the way to go.

4

I had a 7.3 IDI, and after some modifications like a larger turbo, it really surprised me with its capability! Still, I think a stock Powerstroke will beat it every time.

5

True, but the Powerstroke can be more expensive to maintain, especially if you’re pushing it hard. It’s a trade-off.

I’m curious about the fuel efficiency differences. My IDI tends to get around 18 MPG on the highway, while I’ve heard Powerstrokes can do better or worse depending on the tuning?

Absolutely! My Powerstroke gets around 20 MPG with a good tune. Fuel efficiency really depends on modifications.

Some people trash the IDI for being old tech, but I think it has character! It’s like comparing a dependable old friend to a flashy newcomer. Both have their strengths.

9

Haha, I love that analogy! Both have their fans. What mods have you done to your IDI to enhance it?

I’ve added a bigger intercooler on my Powerstroke, and the difference in power is incredible. Fuel efficiency is also better, especially under load. Totally worth it!

That’s awesome! I’m considering similar upgrades for my IDI. What kind of intercooler did you use?

12

Honestly, the debate between IDI and Powerstroke can be contentious. People seem to have strong opinions! But for reliability, I lean towards the IDI.

13

That’s a fair point! The simpler setup does mean fewer potential issues. It’s all about your needs at the end of the day.

14

I’ve owned both engines, and I can say the 7.3 Powerstroke is generally more powerful and efficient. However, the IDI has its charm and is less complex in terms of maintenance.

That’s interesting! I’m leaning towards the Powerstroke for its power, but how does the maintenance differ? What’s the common issues for each?

Maintenance on the IDI is typically simpler, but it can suffer from fuel system issues over time. Powerstrokes can have electrical problems, but nothing a good preventative approach can’t address.

17

Great point! What kind of preventative measures should I take for a Powerstroke?

Regular oil changes and fuel filter replacements are key for the Powerstroke. Monitor the electronic control module too! Overheating is a common concern, especially in towing situations.

I’ve heard a lot about oil change intervals affecting longevity. Which engine do you think holds up better under heavy use?

The Powerstroke generally holds up well under heavy use, but it requires more attentive maintenance. The IDI may wear down faster, especially if not maintained properly. It’s a trade-off!
