Working on a history of Dodge trucks; is this accurate?
Hello!
I'm working on putting together an overview of the development of Dodge diesel trucks between '89 and now. The following is an excerpt from that, covering '89 to '93. In spite of having a 4 letter F-word truck
I've always had an interest in Dodge and Cummins, but haven't followed the history of the truck as well as I probably should have.
Does this sound accurate for an overview? Am I missing anything important?
Any comments would be appreciated. Thanks in advance!

The first model year truck to feature the Cummins turbo diesel was 1989. The engine was offered in 3/4 ton and 1 ton 2 wheel drive and 4x4 trucks, with either a Getrag 5 speed (4 gears plus an overdrive gear) manual transmission or a Chrysler Torquflite 727 3 speed automatic transmission. This marked the first offering in the light diesel pickup market to have a turbocharger as standard factory equipment (although aftermarket turbo kits existed for Ford, they did not offer a factory turbo until 1994). The truck went unchanged for the 1990 model year. Halfway through the 1991 model year, the engine package was changed to add an air-to-air intercooler, allowing for more power. In addition, the 3 speed Torqueflite 727 automatic was replaced with a 4 speed auto, adding an overdrive gear. The engine remained unchanged through 1992 and 1993.
Any comments would be appreciated. Thanks in advance!

Depending on how detailed you want to be, they went from an 18.5cm turbo housing to 21cm in 91.5. Back to 18.5 in 93. Also some pump/line changes.

Re:Working on a history of Dodge trucks; is this accurate?
A couple things: The implication of your wording is that when the aftercooler was added, performance of the engine (as stock) went up. This is not true: performance went down, though the rated maximum hp and tq were unchanged. You might want to point out that the aftercooler was added to lower combustion temperatures and pressure to reduce NOx emissions, and meet new EPA standards.
You also might want to mention that the Cummins in the dodge was not only the first turbocharged full-size diesel offering (there had already been the little mitsubishi/dodge diesel pickups, and the Isuzu diesel pickups, etc. which were all turbocharged) in the American market, but the first direct injection diesel offering (in the US) in a pickup.
Also, I was pretty sure that both Ford and Chevy had turbos on their V8's earlier than '94. I know the last years of the 7.3L in Fords had a turbo, before the PowerStroke came out '94, and I thought the 6.5L Chevy, with a turbo, came out in '91.
Funny, it's not that long ago -- seems like it would be easier to remember . . .

the 93 7.3's were non turboed. If they put a the turbo diesel pout in 93 it was called a 94 model and was only 5hp mor than the nin turbo 7.3 as for the chevy I don't know but 91 is still after 89

I don't think you can accurately say the Cummins powered Dodge was the first turbo diesel light truck. Dodge had a six cylinder Mitsubishi turbo diesel in the pickup in the late '70's for one or two years, '78 or '79 I think. Jeep offered a 1.8 liter 4 cylinder turbo diesel(Isuzu maybe?) in the Comanche in the early '80's, I've seen one, an '85 with a 5 speed. God, that was a slow truck. Those are two examples I can think of, there may be more. It would be accurate to say that the Cummins powered Dodge was the first popular turbo diesel pickup, though.

You could get "club cabs" throughout the 89 to 93 years, just not with the diesel option.. THe diesel clubcab debued in 1992 model year. The same thing happened in 1994.. You could only get a CTD in the 94 standard cab, with the CC available in 1995.
Good history. The GM 6.5 turbo Diesel was in 93 I believe. Ford had the TurboDiesel indirect injection in 1994 and the DI Powerstroke in 95. Aslich is right in that the CTD was the only direct injection diesel on the market up to 1995.
There was an article in one of my old TDR magazines on this. I will have to dig it up..

:-[ Really?? I was under the understanding it was the 95 model year. Oops. I guess it was like the 98 12v to 24v change midway. You always learn something here.. 8)

No they were sold as 94s, although a few of them were sold with the old "turbo diesel" badges rather than "powerstroke". Also, the 94 powerstrokes were only sold with 5 speed transmissions, the powerstroke was not available with an automatic until 95.
