DT466 vs. 5.9 Cummins

On the hunt for a bus and I've read a lot of back and forth on the net about the DT466 vs. 5.9L Cummins and wanted to get some feedback from experienced Skoolie Members on the topic?

What is the best drivetrain from front to back for a Bus Conversion?

Flat Nose vs. Hood also?


Thank you, BandK

best.

Flat or hood?---Preference.
Cummins 5.9 vs DT466. --Preference (and a bit of power).

welcome to the forum... I'm sure better answers are on their way.

Welcome!
The DT466 is an excellent medium duty truck engine.
The 5.9L Cummins is an excellent pickup truck engine.
The best choice of drivetrain depends on what you want to do with your bus.
Horsepower and tall gears are nice if you want to run down the highway.


However many people seem to be quite happy with less power and lower top speed.
Get a bus with the engine and transmission you want rather than thinking you can swap things around later, unless you like spending money.
After changing engine and transmission in my bus I could have easily bought a bus that would do what I want for less money.
In my opinion the back of the bus is the best place for the engine.
Drive as many different types of bus as you can before you make up your mind about what you want.

Except mileage... If you're looking for anything with any size, Im agreeing with This post. Go with the DT466. There are other smaller sized DT's out there too, but get the big one. I have a 5.9 Cummins in my Bus, (30ish foot FE BB). I wish I had the 466 instead. My buddy just drove from Kent WA to Utah in an empty 30-ish foot Blue bird. Claims he kept it around 60, and got 9mpg the whole way, (and still wish he had a bit more pull on the hills)... As for my 5.9, I will likely do some mild pump work, a little injector work, and compound the turbos (it NEEDS it more than I want to admit)....

I'm a total, unabashed DT466 fan-boy.

I just drove my 1998 IH/BBIRD 71 pax skoolie 5k miles to burningman and back. Other than replacing a fan clutch (which was an original, factory part according to tye service records), there was zero drama. The damn thing is a Hoss! Tackles hills with a long grunt and a turbo whine. Excellent engine. Highly recommended.

also remember ALL of these engines came in various variants.. esp the DT's..

my bus has a jasper DT-360 in it which is set up for 185 HP @ 2700 RPM..

there were DT-360s that only pushed out 165 HP.. and there was a 195 HP variant..

the DT-466 also has variants so look up the year and application before you just say "oh its a DT-466"..

I have no idea about the cummins other than I know they are deemed to be very solid / trusted and reliable engines...

Roger that. Nearly all diesels are built in a number of different configurations. Some are set up as pumps & power plants (off road use) while others within a specific designation may be available in a wide range of HP packages for different applications.

For example...the little mechanical Cummins 4BT like I put in my rig can be found from 55 HP up to 170 (mine is 135). Same displacement, just various factory tweakings of the injectors, pump settings and turbo.

So as Cadillac notes...you would be well advised to determine exactly how any engine of interest is configured.

in a way thats why i miss gassers... it wasnt uncommon for me to drive a car with a 210HP 350 chevy into my garage and then a couple weeks later back out of my garage with a 475 HP (same 350 chevy)....

and then of course soon return the same garage with a 5 gallon bucket of gears and metal and bits and back out with a BRAND NEW TRANSMISSION!..
