'94 7.3 non-powerstroke
I'm considering buying a '94 F250 non-powerstroke. Is this a good engine? What is their average life expectancy? All info on this engine would be great.
Thanks. |

We have one with the factory turbo and it still runs great with about 250,xxx miles. Never done anything major. I would recomend it..

Sounds like you have the Powerstroke then. I'm talking about the non-powerstroke.

Ok for general knowledge:
Options for engines: Starting in 93 you could get either the 7.3 IDI NA or 7.3 IDI turbo. In 94 you could get those as well as the 7.3 Powerstroke. In 95 the only option was the Powerstroke. They were all badged the same in 94. They just had Turbo Diesel on the front fenders and on the tailgate. Minimal structural differences exist between the the NA and tubo IDI other than the turbo. The turbo engines are great but you should replace the downpipe. If you remove it you know why. It looks like it got run over by a Mack truck.......they are made that way for some unknown reason....probaby because its a tight fit! Thad |

Diet is correct. It is a IDI turbo diesel.

Life expectantcy: These engine can go a long time if properly maintained. The biggest issue for the 7.3 is cavitation. If the SCA/DCA's have been kept up with then it should be a good rig. But who knows what the previous owners have done to the thing!
They are not powerhouses like the Cummins. If you are icnlined to build a hotrod then go with a Cummins. International IDI engines run a long time but were not built to be powerhouses! If you need a truck that is dependable and a true workhorse then the 7.3 is a great choise. But definately put a turbo on it. Beyond that not much can be done to tweek thse engines.....not to say thats it but it the biggest power gainer! Mine had 185,000 on it and it ran like a top when I sold it! Thad |
