Cummins R2.8

Says the guy with $5/ gal petrol

The only reason I would go diesel is to bring my tractor anywhere in the world to go exploring.

 

Same price for diesel fuel here. But with my work commute being about 10ft (from my bedroom to my home office) I top off my truck once a month so fuel price does mean nothing to me . 60 bucks a month - I can live with that.

Seriously this country is full of diesel engines and they are not cheaper at the pump than gasoline. But on the road you can tell the difference by the cloud of black or white smoke and the smell of burning candle.

Old fassion diesel was simple and reliable engine - hence some farm tractors from 50s still plowing our fields. Modern common rail engines are nothing but the trouble that require super clean and specially treated fuel to not blow a cloud of smoke. Yes, old fassion diesel can run on any fuel including french fries oil. It is not true for common rail engines.

 

FIFY

Guess I'd find an old diesel engine and put'r in there if I ever get to go globe trotting - french fries all over the world thanks to McDonalds

 

I wonder what the 0 to 75MPH times would look like since this engine doesn't have the same rippems as a gasser? I think 8k is just the tipping point by the time one finds out the gear ratios are not designed for this engine

 

Probably not that powerful

Fixed it for you.

 

Yes, but for trucks like that

 

For the $8k I would prefer to do a LS swap. Tried and true reliable power. You could probably finish the whole swap for less than that Cummins motor and the mileage wouldn't be too bad given how light these trucks are.

 

Yeah, if the R2.8 would have been available when I did my swap, I probably would have gone for it. The 1KZ is a really good motor, and with basic mods makes similar or better power to the r2.8, but you can't make it emissions legal.

I'll be looking at the R2.8 for my land cruiser...

 

160 hp in a 5k lb Landcrusier? No way would that be my first choice into that rig.

 

That is actually the only engine offered with 2018 LC in Poland: I4, 2.8 TD 177 hp. That thing doesn't even compare to 5th gen 4Runner. What the hell they are thinking.

 

With max torque available at 1500rpm all the way to 3000rpm, 160hp doesn't even matter.

 

If you keep your 4.10s, 37s are good, 35s are still quite doable.

Keep in mind that this is a diesel, not made for horsepower, made for efficiency & longevity, unlike a gasoline engine. Also it is a Cummins, which means that there is or will be a way to turn up the injection pump to increase torque even more. Will it be legal to do that? Probably not in some states. Will people do it anyway? Damn straight they will. And turn it back down to pass emissions again, just like they do now with the other diesel engines in full size trucks. Once the aftermarket catches up and figures out the tuning, they'll be installing these engines into much heavier vehicles than Jeeps and such. Look over seas and you'll find similar sized diesel 4 bangers in quite heavy industrial trucks and equipment.

 

Really engine torque matters only when you don't have a gearbox (like in a boat). What matters is the torque and rpm at the wheel. 160hp limits it to just ... well, 160hp. With 285 hp I can have 75% more torque at the wheel at the same speed. Simple math. Yes, engine rpm will be higher. So what? It is designed to spin 5400rpm. And people invented gearbox between the engine and wheels to compensate.

I wrote it many times, I like diesel engine for its simplicity, but that was "old fashion diesel", not common rail type with all emission stuff. It is just PITA to have it. You have to perform special driving cycle to "burn the cat". Fuel has to be really clean and specially treated (like gasoline now) to maintain clean injectors. Yes, good luck cleaning them common rail injectors. They cost $200+ each, and when replaced the ECU has to be programmed for the new one (because every injector even from the same batch is different).
Not mentioning that new diesels come with dual mass flywheel which is real PITA on its own.

Old diesel was simple: air in, black smoke out. Pour any kind of fuel into the tank and enjoy the ride. Not much acceleration or fuel economy (not mentioning the emission stuff), but hey, who needs that in a farm tractor.

 

Yes it does...it will be a dog with that weight and only 267 ft-lbs of torque...thats not much at all... International 7.3's are slow when stock because they only have 230hp, even though they have 500+ lb-ft of torque.

Diesel longevity is a myth anymore. Prior to 2008 there was some truth in that, but the reality now is that they require more maintenance than a gas engine. DPF's, DOC's, SCR's, and EGR valves all will fail in 200k or less. I work for a company that runs a fleet of 1,300 class 8 trucks with exclusively Cummins ISX and ISL's...replacing the DPF and DOC is scheduled routine maintenance at 200k...at a price of $4,000. Our maintenance costs have gone up 70% since 2008 to present because of the emissions requirements.

The aftermarket tuning scene is dying for new diesels, the EPA has started to come down hard on non-compliant tuners. Edge took a $500k fine for producing non-emissions compliant tuners. H&S was effectively shut down by a $1m fine from the EPA as well.

 

I am overseas (Poland is somewhere in Europe) . New 2018 Toyota Land Cruser is available only with this size engine: 2.8l, I4 177hp diesel. They don't even try to race here. On a freeway (85mph speed limit), thy have the same performance as a dump truck.

Driving style in Poland quite different from USA. The left lane on a freeway is used only for passing so you better be quick in and out of that otherwise a line of BMWs will start honking and then you get pulled over by highway patrol for dangerous driving. I can do that in my 4Runner (not so much with Tacoma). Acceleration from 65 to 90 is what you need here. If you don't have it, better stay on the right lane with all other diesel 4-bangers.

 

That is correct. Diesel longevity applies to these "farm tractor engines", simple, oversized and not efficient. But boy, they run and run forever. New small diesels trying to compete with gasoline engines are over-engineered with many fragile and very expensive parts (like common rail injectors I mentioned).

 

Sounds like Los Angeles

 

hmmmm $8,000 for the conversion...
that buys 3,076 gallons of gas at $2.60 / gallon
that's enough to go 61,500 miles at 20 mpg

This is a good plan financially? What am I missing here?

 

Has anyone done a swap to a vw TDI? Thought they might be plentiful now and very cheap these days. We don't have emissions testing so wouldn't be an issue for me. I have a Kubota utility farm tractor with a turbo diesel that works hard all day on 5 gallons of diesel and has had zero problems in 5 years. Would love to have the same qualities available in a Toyota truck.
