Post subject:  Diesel Slant?
Was sitting in traffic the other day behind one of the big 3 Diesel Trucks - and was wondering if anyone has ever tried to diesel a slant?

i would imagine the bottom end would be strong enough to take it.

I am guessing pistons and cam would need swapped out to bump up the compression to 20:1

I am not planning to do one, But if I were what would all be involved and is it even possible?

I know there would have to be a diesel invection setup with a throttle body installed.


Just Tossing this out for the brains and number crunchers to munch on.

There was a big discussion about a diesel slant a while back: http://www.slantsix.org/forum/viewtopic ... +slant+six

I suggest you get a keg of beer and look at nitrios or turbo or supercharger. A Slant Diesel hell why not rocket fuel. Hell i doint think Bagel could pull this one across. Thanks Ron Parker :D

The factory did, in the late 1970s and early '80s, with a Bendix fuel injection system and a turbo. Everything but the bore centres were all new. 7-bearing crank, different block and head, etc. After extensive development, they got it working well, but — like many of the successful slant-6 development projects of that era — the company didn't put it into production due to lack of cash, impending changeover of their passenger car range to FWD, and predicted low popularity of diesel engines in America (translation: "Shoot, those idiots at GM screwed up bigtime with the piece of trash dieselised Olds 350, and now everyone's going to tar us with the same brush!").

The gasoline block/head/crank/etc. would not be up to the task.

Dodge had a diesel in the D100/150 trucks in the late '70s-early '80s. I think was Mitsubishi sourced. Didn't have a good feed back, low on power, I don't recall it being a turbo. Even back when new they were seldom seen. If they had used that time and capital into putting the diesel slant Dan described, Dodge may have grabbed a bit more of the domestic truck market.
What I'd like to see offered is a D150 with a Cummins, minus 2 cylinders. It would have 220 HP, 400+ ft/lbs torque. That's enough to tow 7-8K lbs. Fuel mileage would have to be 25+ mpg hwy.

Cecil,

You can always build one. The 12 valve Cummins 6BT(A) as used in the Cummins Dodge's also came in as a 4BT(A). There were plenty of 1-1 1/2 ton panel vans built with the 4BT. Most have the block to bellhousing adapter for Chevy tranmissions, but you can bolt on the Dodge adapter instead.

This is the Mitsubishi diesel that came in 3/4 and 1 ton Dodges in the late '70s and maybe into the early '80s. I'd rather have the 5 cylinder out of the Mercedes/Dodge/Freigtliner Sprinter van myself. http://portland.craigslist.org/clc/pts/221014180.html

Absolute trash. Those trucks were hard to start, put out James Bond smokescreens, and went 0 to 60 in about 25 minutes (downhill with a tailwind). Yuck! :-(

Dan is right, GM pretty much ruined the early diesel market with their half-asz 350 diesel.

I have yet to see one in person though. Probably all relegated to the junkyards by now.

Looks like that what someone did!

That I could go for. Probably needs all kinds of sound deadening though. That's why I think the new common rail Merecedes from a Sprinter would be a better choice. You could hear yourself think.

Some of the newest Mercedes CDI diesels have alloy blocks that weigh similar to a gasoline motor. The Big Three, and probably Toyota are working on lighter turbo diesels for 1/2 ton trucks in the 3.5 to 4.0 liter range, Dodge's will probably be sourced from Cummins rather than the Germans. I read that these diesels might be available in 2008/9

In COMPLETE contrast, I was sitting at a light a few days ago and an old (early /mid 70s) diesel IH Scout pulled up beside me. Light diesel rattle, nothing like the noise an older Powerjoke makes. And when it pulled away it MOVED, left no smoke, and no stink. I have no idea if it was the original engine or not, but if it was that was one heck of a sweet little diesel.

The '70s diesel Scout would have had a Nissan 6 cylinder diesel. They were normally aspirated and slow. Good engine though. Later ones were turbocharged so it wouldn't surprise me if the one you saw was updated.
