I am looking at buying a F250 Diesel and I have found a 1994 Turbo Diesel and I was wondering how much difference is there between the turbo and the non turbos. Is there a big power difference? What about reliability differences? Also will both these motors in a 250 be able to tow 10,000 pounds if I need to every once in awhile?

 

oh yeah!! it will pull 10,000 lbs every once in a while. if you have aan auto tranny, you need to get a BIG tranny cooler with a fan, maybe 2 of them. the e40d's get really hot, if its standard then roll on. there is no big power difference in the 93-back 7.3's and the 94 turbo diesels. "they do make a 94 owerstroke that they called turbo diesel" but if it has an injectoin um its allright. i know a guy that took the turbos off the 94's and he says it gained power so i dunno.

 

I had a nice F-250 with 460 gas and traded for 1992 Diesel had 48,000 on it... and the power was the same when pulling in the mountains... problem came when I got above 5,000 ft the diesel smoked like I was setting the forrest on fire... and power was down... went to Banks and put on turbo and HEY, now we got the power and no high alt. smoke... I would never purchase a diesel without a turbo again..... I weight and tow 15,900 lbs when loaded.

 

The difference between a turbo and no turbo 7.3 is about 100 foot pounds of torque and 10 or so horse power.

Ford really messed the stock turbo up with a small exhaust pipe and a smashed down pipe. The turbo outlet housing is to small as well.
The stock turbo is an ATS turbo that was re-engineered by Ford. ATS can sell you everything you need to straighten it out so it works right.

If you get a three inch exhaust on it from the turbo back and a three inch turbo outlet flange the difference will be on the order of 40 HP and 150 pounds of torque more than the 7.3 non turbo motor.

 

Were the IDI 7.3 turbos intercooled like the PSD's or not?

 

The turbo IDI engines were not intercooled.
The early Power Strokes were not intercooled either.

 

ATS also has intercoolers for these trucks
