Van versus Truck Motor differences 7.3, 6.0 diesel questions.

Wondering if anyone would like to summarize the differences between the 7.3 and 6.0 diesel motors in the vans and the trucks.

1. Why does the truck motor produce more hp/torque and the van less? What does it have that makes it different than the van?

2. Does the van have the same motor with some parts missing or are they two differently built motors?

I think the intercooler on the trucks is a key factor.

Re: Van versus Truck Motor differences 7.3, 6.0 diesel questions.

My experience putting the 1999 7.3 ambulance motor into my 1975 Econoline taught me several things. Many things are common between the van and truck engines in that many of the brackets I had on my ambulance motor (from a dually van cutaway)were actually the pickup parts. When I wanted to add the Banks upgrades they only make them for the trucks. I bought the power pack kit anyway and have installed everything, but the intercooler which will go in over the winter. The turbo unit is the same outside on both, but the van version is lower output (smaller diameter inside). Side by side the van and pickup turbos look the same and bolt on identically. The turbine units are mostly different because the van doesn't have a wastegate. I picked up a used pickup turbo/turbine unit and gutted it to use the upgrade parts from Banks. It bolted onto my van engine just fine and works great. Using the Banks "Big Head" wastegate actuator connected directly to the air line on my map sensor it is dumping excess exhaust at about 25 pounds of pressure which Banks indicated it should. The remaining parts of the Banks Power Pack kit included a Trans Command unit to alter shifting (which hooked in the same on the van as a pickup) and new 3 1/2 downpipe and 4" exhaust. I had to slightly modify the pipe bends to fit in my van. I did it by cutting out small wedges of pipe and then re-welding it together when I needed a bend. Some restriction, but much better than the old downpipe (which is smaller stock on a van than a pickup)and the original 3" van exhaust.

The 2004 6.0 has an intercooler, but is limited electronically due to airflow issues in the engine compartment.
