1HDT FTE is the ultimate development of the 1HZ best of the Landcruiser Engines before the V8 rubbish , 6cyl 4.2L Turbo Electronic Fuel control.
Only Yanmar do them better, they make great boat motors (seriously)

I had a 1HDT cam seize / throw a belt at 560.000klm, motor had never been apart , not a bad innings.

Hi Justin, you can always borrow my 90 for the heavy stuff if you like!!!
Going beautifully after its regular service with you last week thank you.
Cheers, Peter.

wasnt that the idea???
If all you ever put in it is fuel, you'll be miles in front

Hi Pedro,
Yes mate really enjoyiing the view, and the quiet, but NOT the wind and getting blown off the road by trucks..... Even had a Duratorq Transit blow past me today towing a little poptop...

The holiday will be over next week so will be at one with my Isuzu etc until then and enjoy it Then back to the real world

Sorry mate but this is a consequence of towing a heavy van. Cant compete with 2000 odd Nm of torque and multiples of gears. Just watch your mirrors and keep left. I've blown off many different Jap tugs and the look of amazement was priceless. Probably because they were retired and in no rush but it still topped up my ego!!!

What s the torque on the 3uz at 1400 RPm
Thanks AM

Thanks Robbo, yes I am well aware of the keep left and watch mirrors; today was the worst though with the strength of the wind the direction that it was. Passing trucks would push me over then suck me back in again!

I would be unable to pass any other vans etc I reckon unless they are very slow, I am happy up to 105 without a headwind, then the temp gauge starts to creep up a little. I haven't an EGT gauge fitted back in there as yet but have conservative fuel settings. This takes me back to towing over in the west when I was younger, quite enjoy it really

23 foot! That is quite light though? ATM 2580kg is very good for a big van.

Some food for thought.

The 4BD1T and 1HD-FTE have basically the same peak efficiency. ~210g/kwh at rated torque.
The displacement is within 10%.
So given the same fuel and air, the 1HD-FTE is going to deliver the same results. The increase in displacement and 4 valve per cylinder means it can deliver a fraction more airflow for the same boost.

So the only way a 1HD-FTE is going to deliver any more power is by spinning faster, which is where the efficiency drops and fuel burn starts to really suck.

At lower loads the 1HD-FTE with more internal friction (two extra cylinders) suffers an efficiency penalty and burns more fuel. My fathers 1HD-FTE cruiser has just done 200,000km from new and has never broken 10km/litre. Even when driven like the proverbial grandfather (the steering is too vague to drive it fast anyway).

So.
You want more go. You need more boost and more fuel to go with it. It's that simple. Changing engines ain't going to help much.
You'll also be looking at something better than the LT95.
