looking at a 110 with a diesel, but don't know anything about diesels. where can i found out about which ones are good and the ones to stay away from any info or websites out there?
Normally such statements would irritate the hell out of me, but the fact is he's absolutely positively right.evilfij said:burp . . .
well they do :flipoff2:

Sorry to rain on your parade, but it'll NEVER happen. 140 hp out of a diesel? That's the same figure as an Isuzu 4BD1, Cummins, etc. You'd be looking at almost tripling the output of this engine. All engines that put out this sort of HP reliably are either expensive or very very BIG. Think CAT, or a Perkins 4-236.antiredneck said:burp,
I'm thinking about putting a 2.25 D (mostly out of curiousity) in my RR if I ever blow up the 3.9.
I don't like the idea of a timing belt in a truck engine.
I'd like to experiment with a low pressure (5-6 lb.) turbo to see if I could get 140-150 (reliable) hp.
I just like those old engines.
Dude, you are the man if you build a 130" wheelbase RR with a 2.5L rover diesel, with a K box turbo.antiredneck said:No, but I'd like to rebuild one (2.5) and fabricate a low pressure, intercooled turbo intake (maybe from a junkyard turbo k-car) and see what it does.
The article goes on to state that the engine had a redesigned block, pistons an exhaust valves. The article also desribes the bottom end as "... a bit overstressed" and notes that early engines suffered from bottom end failure. The article also describes the engine as being reasonably reliable (all the early duds died or were rebuilt).There's nothing inherently wrong with it, but it's [2.5 TD] been totally eclipsed by the significantly better TDI engines...
Yeah right.Momo said:Ford Powerstroke- now THAT's a diesel!
thats great and all but that doesnt mean that a V8 diesel is crap. the powerstroke is a VERY good LIGHT TRUCK DIESEL. last i looked my land rover wasnt a medium or heavy truck. what you described is true, though, to a point.Fear Factory said:
Yeah right.
Why do people purchase V8 diesel engines in pick up trucks when their class 8 truck runs an inline 6 cylinder engine? In fact there are no trucking companies in the U.S. that utilize V8 diesel engines. Lets compare the V8 to the inline 6 engines.
1. Block: Inline 6 blocks are much heavier and more rigid than V8 blocks and that is why the main bearing caps are not cross-bolted.
2. Crankshaft: The inline 6 crank utilizes 7 main bearings, the V8 has 5 main bearings. Each connecting rod on an inline 6 has its own journal on the crankshaft and the V8 has 2 connecting rods per journal on the crank.
3. Connecting rods: The inline 6 rod has a much larger rod bearing, wrist pin and wrist pin bushing than the V8 rod.
4. Pistons: The inline 6 piston has a thicker dome, longer skirt and larger wrist pin bore.
5. Exhaust manifolds: V8 diesel engines exhaust manifolds have extremely sharp 90 deg turn ups on the back side and the exhaust travel up to the turbo. The turbo is a great distance from the front cylinders thus allowing the exhaust a chance to cool down before entering the turbo. The hotter the exhaust the quicker the turbo spins. On an inline engine the turbo is positioned right between the #3 and 4 cylinder.
6. V8 engines produce more horsepower than inline 6 engines. However the inline 6 has a longer stroke, which equates to more torque and torque is what pulls a load up the mountain. Horsepower is good for acceleration with light weight.
Not sure what your point is. Commercial trucks? Over-the-road freight trucking is entirely irrelevant here. That said, I see a lot more Powerstroke V8 equipped Fords in commercial and municipal fleet service than Inline 6 Dodges, and in all kinds of configurations from power company trucks to railroad trucks to light-duty fire apparatus.Fear Factory said:

There are a lot more factors that go into why commercial trucking companies typically choose inline 6 diesel engines over V8s. And those reasons are not necesarilly valid for the consumers market. Commercial truck companies are looking at a very specific market in terms of rebuildability, economy, fleet maintenance costs etc. And many of the engine makers that cater to that market are far more reluctant to retool than automotive companies. This is why Cummins proposed an aluminum head V6 diesel instead of an I6 for the light truck market, but have not produced one.Why do people purchase V8 diesel engines in pick up trucks when their class 8 truck runs an inline 6 cylinder engine?
