duramax in a K5?? can it be done

[ QUOTE ]
Isuzu is the #1 producer of light/medium duty Diesels in the world.

Where did you see this? AFAIK, Navistar is the leader in the medium duty market, at least in North America. Isuzu isnt even on the list we get at work. Light duty might be a different story, just want to know where you get your info.

Source is a claim made by Isuzu about four years ago. The actual claim was "below 300 horsepower" IIRC, which generally one would think would imply light/medium duty Diesels.

You may be correct about Navistar in North America though.
 
You used a claim that was 4 years old from Isuzu and presented that as fact? Interesting /forums/images/graemlins/thinking.gif

Wouldn't it be false advertising to make a false claim?

Got any reason not to believe it to be true?
 
I dont believe their claim plain and simple. Numbers can be skewed to make their product look like it sells more. Is this on and off highway, light and medium duty or just light duty?

This is engines under 300 HP worldwide.
 
Doubt its true then being in the business and all. Even if true, as mj alluded to, selling the most doesnt make it the best, maybe the cheapest or easiest to service, not the best though. /forums/images/graemlins/thumb.gif

May not be the most efficent, or modern, but I've always liked the old Detroit Deisel engine. Both supercharged and turbocharged. Would probley fit in a K5 too. But I think I'd have too do a Cummings Turbo Deisel.

Two stroke Diesel? I think that's a little obnoxious for a road vehicle. They are not designed to be operated that way anyway.

/forums/images/graemlins/confused.gif Two stroke Detroit diesels were all over the road in semis in the 60's and 70's. I remember when I was a little kid when my dad still had a couple of those early trucks, they had decent power, wound up FAST, and smoked like a freight train. I bet it would be a good motor in a pickup mainly because of the RPM's they are capable of and how fast they wind up.
 
They are talking worldwide. I read this little fact in 4 Wheel and Offroad a while back. Yeah, hard to imagine that some Japanese company would be #1 in something, USA isn't always the best like it or not.

they are HUGE in the Asian market and just about every other market I can think of other then North America
they power all the Hitachi excavators at work etc etc

I will never own a Duramax.
they take the simplicity of the diesel and bury it in a pile of computer crap.
I used to think computer controls were The Thing but the more I learn the less I like them.

you do not need an injector lobe, you just have to hydraulically connect it to a lobe on an opposing cylinder that would be opening about the same time as a real diesel injector lobe would be firing.
would be a bit of a hose monster.
simple, and I bet it would sell to the Bomber crowd.

This quote just doesnt make senese.


[/ QUOTE ]
Oh, and why is that?
I think it makes perfect senese. Let Me ask You a question. Why doesn't GM put the Duramax in the Tahoa/Yukon (the modern day version of a K5)?
I'll tell You why cause it makes no senese to put an engine with that much torque into a vehicle that does not need it. A K5 does not need that kind of torque cause it does not pull heavy loads. Gears are whats needed in a K5.
 
[ QUOTE ]
Real Jakes on a C series would be very hard since there is no injector lobe to use to actuate the exhaust valves

now from Jake website
[ QUOTE ]
On older Cat 3406,3406B and 3406C engines, and Mack E6 and E7, the slave piston for one cylinder is controlled by a master piston following an exhaust valve of another cylinder

[/ QUOTE ]

so I am not suggesting anything they do not already know /forums/images/graemlins/smile.gif
 
I kind of think it is because the Dmax is an extremely expensive engine and they do not think they will sell enough to justify the production run.
there is no such thing as too much torque.

it amazes me how the chevy faithful jumped on the Dmax bandwagon with nothing but faith.

My next new truck will be an F-350 with real hubs and a real t-case shifter /forums/images/graemlins/deal.gif
BTW I will be picking Your brain in the future on converting MY 76 C-20 to 4 wheel drive. I think I got the basics but there maybe a question or two later /forums/images/graemlins/deal.gif

I doubt it, it is extremely easy
except finding an uncracked engine crossmember
 
Didnt say impossible did I? I am quite aware of the systems on other engines that do not have cam driven unit injectors. I did however say it would be very difficult and I still stand behind that.
 
Out of curiosity, if you still drive OTR trucks, what engine powers your rig(s)?
 
Too much torque? K5 doesnt need it. That makes even less sense to me.

If youa are going to go swap in a deisel... why that? ONly reason, cause it would be easiest. But, I can build a 350 for way less and make way more power.

And talk to any Suburban owner... they would take a Duramax in their burb any day, if they were shopping for a deisel.

I doubt you could build a 350 that makes way more power, and even if you did it wouldnt get sh%t for mileage.

Dont think ti would be the easiest swap either.
