Is your engine a 7.3L IDI?

Then I would really appreciate to hear your experience with it!

I've spent all day searching this whole forum for any and all references to this engine, and I've come across a lot of posts saying that they would not even consider it for a Skoolie, as it is underpowered. But I also see that quite a few of you have one, and is supposedly a very reliable engine, and easy to work on.

This week, I'm going to see a 40' 1992 International 7.3L IDI (200k miles). This particular bus checks all the points on my list for the exception of the engine. I have also been looking for a few months now, and where I live it's hard to find anything worth even taking a second look at. I'm at the point that I will have to start making some compromises if want my road trip to happen.

My conversion will be drive across Canada/USA for a year starting next March.

Thank you!

Sure you want an IDI? Those buses are SLOW!!



Even a 5.9 Cummins or a T444E would be a better choice in my opinion.

Lol... I think what I want is to hear that that engine will do

I'm not concerned about speed, as long as it's not dangerously slow.

This particular bus is already registered as an RV, which saves me a BIG headache, as in Ontario it's a pain in the bud to get insured and so on... It's also a very clean bus, no rust, which is hard to find around here.

I just can't wait to get a bus and start working on it.

How far you plan on driving it?
An IDI on a 40 footer is gonna be a dog on the highway or on any inclines.

I had a 7.3 idi in a pickup F250 with a three speed automatic and

i was very happy when I got a powerstroke. Later I got an E350 7.3 IDI with a 4 spd and in the mountains above 4000 ft it had a hard time getting out of second gear. We ran a lot on WVO in that time and yes these engines are simple but not great for WVO . The injection pumps wear out, even on diesel and the first symptoms are hot soak, no start.



Good luck, j

My 7.3L

I actually have a T444E, which in almost all ways is a 7.3. My bus is 33', just over 19k lbs and I do 64mph at 2600rom (governed). I have an Allison 643 4 speed with torque lock in 3rd & 4th. Going up two different steep inclines it's going about 45-50mph. My biggest limitation does not appear to be the engine but the tranny. I'm very open/interested in a 5 or 6 speed for lower cruising rpms and closer shift points in a tighter power range.

From another forum-

Quote:
There are 4 parts that are the same between the 7.3L IDI and T444E (7.3L Power Stroke) engines.

1) Oil cooler bundle
2) Front oil cooler header
3) Camshaft lifter
4) One other part, I *think* it's a pushrod.

Thanks for your input.

When you guys say it will be a "dog" or "SLOW", what are we talking about? 60mph? 50mph? Like I said before, I'm not so concerned with speed, as long as I'm not causing accidents when merging onto the highway.

I am going to test drive it and that will probably answer a lot of my questions.

EDIT:

Also, would adding a turbo kit be a silly thing to do?

The IDI is a great engine... in a pickup or small bus. NOT in a 40 footer. The IDI is about 180 hp, while a bigger engine like a DT466 is 210 and up. And the DT will have 2x the torque at half the rpm.

This engine will be really struggling to push it even on the level. Unless you plan on just going locally with it or repowering, I would pass on it. On mountains this engine will be wound pretty tight just to get up the hill.

Acceleration will be poor, performance on the hills will be poor.

Like bluebird90 said, it's a good motor in appropriate applications. A full size bus that will be driven cross country is not the appropriate application.


You can spend several thousand dollars on a turbo, inter cooler and injectors to make more power. It will come at the cost of reliability and longevity.

Perhaps it would be better to save your money for well equipped bus.
