SO, what are the differences in these engines the way they were installed in typical form.
What parts will not swap between the two.
Do they have different turbos/hpop associated with them.
Exhaust manifolds? thermostat housing? ECU?
I heard that some had different injectors, but which ones?

I figured one of the differences would be the bellowed up pipes.

 

I have bought several parts from the international dealer.. never was I asked anything, and everything has bolted on..would you like a catalog?

 

Absolutely. The International parts counter here has always been pretty leery of selling me anything. I always get the run around saying that I need the exact part number to be sure.

 

T444e is painted blue and and has a steel ccv tube which I want to find for my truck

 

i had always assumed they were the same...guess not...

 

David saying the t444e is like the super duty 7.3 psd, Is like saying the super duty 7.3 psd is like the obs 7.3 psd. Does that make sense?

 

whenever i go to international i just ask for the t444e parts and they always work for my psd.......

 

There must be more things different, I have heard of a few things like injectors and the ccv tube, but just wondering if maybe pistons or turbo were different as well.

 

Depends on what type of vehicle the T444 is found in, I believe. I know the AC codes were found stock in a lot of the dump trucks and busses.

As for the bellowed up pipes, those just came out a few years ago. International used the same crappy pipes found on our trucks.

also the spider set up is different as the dump trucks have a filter off the passengers side of the cab and no intercooler

 

Didn't some of them also come with a coolant filter?

Stewart

 

idk ive only ever seen 1 in person

 

ummmm....nopeno idea...

 

i found a u pull it yard with a whole bunch of school buses with the t444e are the turbos and injectors good for anything or worth anything?? probably can get them for $ten buck a piece

 

My Father in law has a 95 International tow truck with the 444e. This is what I noticed that is different from a 7.3 Powerstroke.
Turbo charger is standard rotation vs. reverse rotation.
Front cover.
Water pump w/built in filter head.
Accessory pulleys idlers etc.
ECM is different and not OBD II. Navistar propriety. I believe many of the senders used to feed the ECM and the wiring is different.
