Thoughts: 4.0L v6 petrol vs. 4.2L i6 Diesel

[saillaw]

I'm currently in the process of trying to decide what new vehicle to purchase. I have narrowed it down to either the 2013 LC200 GXR diesel, or a 2013 LC76. The 76 is much closer to what I really want, but since my wife will also drive it often, I am still considering the 200.

The problem with the 76 is that I cannot get it with the v8 diesel that is available in Australia. My options are either:

1) 4.0 Ltr, V6, Petrol EFI, VVTi, 228 HP / 36.7 kg-m (SAE-Net) -- This engine is only available in the bare bones base model 76.

2) 4.2 Ltr, 6cyl, Diesel, 128 HP / 29 kg-m (SAE - Net) -- With this engine I can also get such items as: D + P airbags; snorkel; alloy wheels; front and rear diff locks; winch; over fender flares; ABS, and rear disc breaks.

I'm driving a rental car right now, a Toyota Yaris. I filled it up with petrol yesterday from bone-dry to full and it cost me US$4.53. So, the cost of petrol v. diesel is not as big a deal as is added range I might get from the diesel (any ideas on the comparative mpg or L/100km of these two engines?).

Getting so much less HP and torque from the 4.2 diesel has me concerned. I of course would welcome the (presumably) better mileage and range of the diesel, but since much of the driving I plan to do is desert driving I wonder if the 4.2 will simply be too under powered?

Any ideas if the 4.2 is a turbo diesel or is it naturally aspirated? Is it easy/possible to improve the torque and power of the 4.2 aftermarket?

Unfortunately, the way you buy cars here you don't get to look at them before you buy them so I can't simply open the hood and look to see if it has a turbo.

What would you guys choose and why? Thanks in advance for your thoughts.

If petrol is that cheap ,get the V6. The newer 76 series have 130 litre tanks.
I would even consider the V8 petrol 200 series.
The 1HZ engine is naturally aspirated,toyota no longer make a turbo diesel 6 cyl.

When you say "desert driving" ,does that mean offroad,or poorly maintained desert roads?
The 1HZ will still push you a long at a reasonable speed on anything except soft sand(although I have never been seriously stuck with tyres deflated to 17 psi).

The 1HZ will get you around 12-14 litre /100klms ,the V6 will get around around 15/17 litres/100klms(based on what the Prado/Hilux get as they have the same engine and similar weight)

If prado get 15-17 litres per km, 76 might get 17-19 due to its non-streamlined "brick" design

There are turbo kits for the 1hz. Will increase the output by quite a bit, but some people have had problems with after adding the turbo.

but some people have had problems with after adding the turbo.

Discuss, aside from the "too heavy on the skinny pedal" problems.

Many have added the turbo with great results, and as long as it is set up properly, you have the right amount of boost, and don't hammer on the motor the 1HZ is great turboed. Is it going to be comparable to a twin turbo VDJ the Op is looking for? No, it's still essentially a tractor motor, but I am quite please with my troopie with the Turbo Glide compared to a NA 1HZ

Thanks guys, how much should I budget to add a turbo and are they difficult to find/install?

Hi All:

I find it rather interesting that the diesel version of the 76 Series with the 1HZ is the luxo model with lots of options, while the petrol version with the GR-FE V-6 is the spartan "work" truck! Usually, it is the other-way-around!

I'd think long and hard about how you will be using this vehicle, how long you plan on keeping it, etc. before deciding on the engine.

The 1HZ properly maintained will last 500,000 KM without issue, I'm sure. The GR-FE I'm not so sure though I'm hoping!! (Have this engine in a Tacoma 4wd pick-up I'm hoping to own for 15 - 20 years.)

The V-6 petrol engine will be much more enjoyable to drive in a heavy rig like the 76 Series versus the 1Hz due to the extra ~100 HP. And since petrol is so cheap where you will be operating the vehicle it almost seems like a "no brainer" to me.

But, if I was choosing a "bush truck" for long-term back country travel I'd choose the 1HZ over the GR-FE due to the reputation for reliability and ease of maintenance of this I-6 diesel engine.

Good luck!

Hi.

I am actually looking at a similar thing but in China, and it seems that over all the v6 is the way to go. And if you are still missing power or torque, it is always possible to add a supercharger, TRD or URD and go big .

Even the HZ engine is sensible on low sulfur fuel, a few guys got problems with their IP when coming back from Egypt and Lybia.

I haven't been conviced by the HZ's, i have a HDT 80 in Europe and been trying several HZJ before going for it. Over all, on my last expedition to africa a friend broke his second gearbox on his HZJ78 (I already posted pictures of the damages and my repair here so he could get back home, unbelievable but Toyota algeria did not had any spares for it, no housing or even full gearbox available)
This 78 was without turbo, just pacemaker 6/2/1 header and full loaded for a deep sahara trip, as all of us.

2 gearbox in 80 000km (first one changed under waranty by toyota and the second one replaced by a second hand H gearbox from an HDT80), toyota definitely did not do a good job on that part for the hz. The R gearbox are not for heavy loaded hard work.
So far i understand the grj 7 come with the H gearbox, an other world.

Going the HZj route, ...yes if i can put a HDJ 80 engine and gearbox setup, but that pays for a lot of gaz and to put in a 1GR.

I'm leaning towards the 1hz now because of dual airbags, ABS, rear disc breaks and dual lockers. I hate that I have to make this choice, would love to give the people who decide the Middle East specs a piece of my mind.

this .. ^^^^^^

Would like to understand the hole Mr. T concept behind this ..

I totally agree that if done correctly its a great mod. I think that if someone does go this route they need to make sure it is installed by a reputable mechanic or read up a lot if they are doing it themselves. If they don't it could go badly and get very expensive fast.
