Late Brake Show 70 Series range rundown and review

[Eurasiaoverland]

The UK-based Late Brake Show has just put out a brief review of a few different 70 Series models (79, 78, 76 and 71) which are currently available globally:

It's more tailored to a UK audience, where we don't really have what Americans call 'full size' pickups. Also maybe not so useful for those in the Land of the Free due to the import regulations...

As someone that thinks Toyota really screwed up on 4 cylinder Land Cruisers (phasing out the excellent B Series diesels in the HD 70 Series for the dinosaur 1HZ), I do personally wonder how robust the GD diesels will be long term.

Hello,

It remains to be seen if Toyota got the heat management right with the 1GD engine. Designers insisted it was an important issue; they mentioned that it was necessary to slant the radiator a little to improve airflow and other details.

So they're already priming the customer with the thought that they'll need to replace the engine in less than 500k miles?

hahahaha so true, ive never felt we enjoyed any more "freedom" than most countries around the globe.

I've never had anything to do with the B series engines, what was so excellent about them?

I think in these days of planned obsolescence where some manufacturers make engines that can't even make the end of the warraty, half a million miles would be quite an achievement.

Toyota stopped putting the B engines in the 70 Series at the end of 1989. They had received the very reliable, if somewhat underpowered 3B and the excellent 13B-T. I understand that the old IDI 3B was ready for retirement (though the 3BII seems to have been quite an improvement on the old 3B) but the B engines were developed into the excellent 14B (3.7 l) and 15B (4.1l) platforms. IMO Toyota could have either used one of these, or slightly refined it with a SOHC into an excellent 3-4 litre 4 cylinder, all mechanical DI engine with a turbo that had similar power and more torque than a 1HZ with better fuel economy. Instead they made the 1KZ based on the same flawed turbocharged IDI principle as the 2L-T and those things are pretty much guaranteed to crack a cylinder head if they get slightly hot.

What makes the B engines great IMO is a basic, robust design (gear driven, iron block and head, very strong bottom end) and that they actually refined the platform progressively to add direct injection, 16 valves and EFI, albeit while retaining the ancient pushrod/OHV design. The only decent 4 cylinder, mechanically controlled turbo diesel that Toyota ever put in a Land Cruiser was the 13B-T if you ask me.

Like a 4 cylinder version of a 2H?

(with larger displacement per cylinder)

A 3B is effectively a 4 cylinder 2H, the 13B-T would be something like a 4 cylinder 12H-T.

 

[HZJ75 FARMER]

Yeah righto. The 2H was/is quite good in my opinion.

I like fillings in my teeth and the 3B is downright dangerous to drive on US freeways.
NO FOUR CYLINDERS (except 22R)

1HZ "dinosaur" is now on 35 year.

15BT would be awesome in any 70 series.

Except the 22R? They are even weedier than a 2L-T.

Fine if you don't like 4 cylinder engines, but have you ever driven a 14B-T, 15B-FT or for that matter a 1KD-FTV? Different experience to driving a 3B.
