Not a truck but still has the cool factor!

that is pretty awesome. Im not too happy with cummins right now though. I have a 07 International 9900I with the cummins and I cant pull more than 5 mpg out of it and its got right at 200,000 miles on it.

My old truck a freightliner classic with a c12 cat would easily get 7 mpg. Big difference when you have to achieve at least 6 mpg to get the quarterly fuel bonus at my work.

That is too funny, hearing that Monte Carlo approach and sound like a truck.
Man, the torque that thing must have.

dumbucket, I'm not a trucker but have read where most drivers agree that the driver is the single most important factor in fuel mileage. Some of the things that increase mpg-(as if I need to tell ya huh?)
Staying close to the 55mph limit. I think if the company specs a truck for 60 and the driver does 70 he's just blowing money up his stacks.
Minimize your idle time.
Watching tire pressures.
Keeping the rpm and boost down
Stepping on the accelerator pedal like it was crystal- yeah I know-it makes for some slow acceleration!
taking it easy on the pedal while you're going thru the gears.
Well those are some things the driver can control. He can't do much about the trucks gearing or distance between cab and trailer or aero setup unless it's his truck. Good luck with it- tough way to make a living these days.I hope you can get that bonus. Maybe a combination of small things will put $ in your pocket.

Its acually these new egr smog motors thats the problem. I have been driving the same route with the same trailer and same driving style for years. Im a local driver and I live in illinois and the speed limit for big trucks here is 55. So ya the trucking industry as a whole is struggling with mpg with these new egr mandated motors.

Seriously, what would it take to install a diesel in, say, a monte carlo?  Please be very, very detailed as i know next to jack about diesels.

Actually, let's divide it into two categories:  the first, non-electronic controlled engines(i guess we call these   "mechanical?") and then 2) electronic controlled engines.

As far as physically mounting the engine in the frame, i'm not too worried about that because it is fairly straightforward;  Making mounts is fairly straighforward if you can weld or know someone who can.

I'd be willing to bet that the cummins cannot bolt right up to any GM transmission, but believe it or not, this does not worry me either because i know shops with CNC machinery that can make a custom adapter plate.

What i am worried about, however, is everything else:

(First, "mechanical", non-electronic engines:)
1)The fuel pump;  Do diesels run an electric pump?
a) and the fuel line/system in general.  What about this water separator thing?

2)Can a diesel use the same radiator as a gas engine of comparable size?

3)Electrical;  What are the electrical demands of a diesel engine, if any?  i know they don't have spark plugs or distributors of course.

4) Anything else?

Then, all the above 4 concerning newer electronic engines.

thanks.

I removed the post as it had no information or content, Just a Quote ?? 
You might try tracking down the guy who did the swap for some first hand information seeing how he has done it.

I do know that the cummins engines have a plate that bolts to the block and then the transmission bolts to that plate.  One of my customers has a 505 Magnum engine in his shop floor right now.  

I also know that on irrigation engines they just use a transfer pump that resembles a mechanical fuel pump on a gas engine.

If you are going to be unique why don't you install a John Deere diesel in it.
