Landcruiser diesel turbo or not

Definitely the turbo. You will become very frustrated with the std injection, particularly towing that load.

Normally aspirated wouldn't pull the skin off a custard.

Definitely the turbo.

For several reasons

A Power A 1HZ is 96kw and 285nm

A 1HD-FTE is 151kw and 430nm

B the later one has a 5 sp auto.

People on pushbikes can pass 1 HZ's uphill LOL

However you should only tow in 4th in the 5 sp.

Lots of threads on this on here and C& M forum


A V8 Petrol has even more grunt but has a thirst to match.

Towing a bit more than you I get 17.5L per 100KM

Get 10.4 L per 100km solo loaded up.

Unfortunately you could pay double the price for the later model but its well worth it.

There are a couple of things to consider. The HDJ100 Landcruisers, which is the factory turbo model (1HD-FTE etngine), only have a Independent Front Suspension. Generally this is more suitable for onroad/gravel road work.

The HZJ105 (Note the 105) are the models with a solid front axle. These came with the normally aspirated 1HZ motor. After market Turbo's are available for this engine, which boosts the power and torque up to near what the factory 1HD-FTE engine produces. However the 1HZ Turbo engine is not as stong and reliable as the Factory engine so it is less suited for heavy towing.

I personally have a HZJ105 with a Safari Intercooled Turbo on it. Without the turbo it used to be a real slug in hilly terrain (like Pentland Hills outside Melbourne or the Toowoomba range). Also, it was difficult to overtake in.
On the Pentland Hills, it was a 3rd gear grind at 80 Km/Hr. With the Turbo it will sit at the 110 Km/Hr speed limit in 5th gear. That is how much difference it makes. But, I do run a Exhaust Gas Temp guage, and going up the Pentlands at 110 pushes the EGT to the safe upper limits. Backing off by even 5 or 6 Km/Hr can have a dramatic effect on EGT's, dropping then by up to 100 Degrees (Pre turbo). Remember, this is without any weight on the back of the car, so towing a heavy van on hills like that you would really need to watch your EGTs. My EGT guage has a lound over temp alarm on it that I set to a nice conservative value. When the alarm goes off I back offf.

Hope this helps

The factory TD has a decent manual gearbox (H series).
The 1Hz has a smaller Prado gearbox (R series) that has a habit of breaking if you tow or add a turbo.
Automatic transmissions are OK for towing.

Also if you add a turbo to the 1Hz you run the risk of piston or precombustion chambers cracking. They are also more likely to overheat.

Fuel consumption is better with the factory TD.

We have a 2005 4.2 TD 100 series and the son has a 2003 model. Both would pull 2.5T easily.

Duncan,
I have a 2004 LC100 auto TD. The best tow vehicle I have ever had.

I also have a 1994 IHZ troopy (non turbo). Great vehicle on its own. Never use it for towing as it just lacks the grunt. I do not believe the 1Hz is sensible for an after market turbo and lots of towing. It just is not designed for it. I know many will say they have done it and no problems.

The factory TD, especially the 1HD-FTE, was designed for hard work and its reputation is excellent.

cheers

Definately the turbo diesel - better fuel economy by about 30-40%.

Proof - there was three of us in 100 series cruisers in convey doing Cape York 2971kms. Two of them not turbo - cost of diesel $620. Ours was Turbo diesel - cost of fuel $380.

Theory goes, the quicker you get to cruising speed, the less fuel you then use.
