HZJ73 vs BJ74

[Jim_Hbar]

Still waiting for my HZJ to show up from Japan - when it is here, I'll crawl under it and let you all know what diff it has in the front.

Wayne - what turbo set-up did you have experience with?

I agree the HZJ will be more expensive, however I do not think the BJ74 will depreciate much if any, as the drivetrain will be in demand for years...imo

They are not going down at auction...if anything the opposite...as they are getting harder to find in reasonable shape, with all the options and H55F...like the HJ61.

Thought the consenses was the lack of BJ74s and availability of 73s would make the 73 a less expensive buy???

It will havee a small gear (8") high pinion front axle. The change over date was Jan 1990.

Consider this confirmation.

The cable locking diffs are still available from Toyota and are a decent deal compared to the ARB, no installation fee, minimum time to install and very simple operation. Leaves you with two spare diffs as well.

If I had to chose between a HZJ73 and a BJ74 I would take the BJ74 everytime.

And I have been in more of both models than any of you would belive.

I have agreed to dissagree with Marko at Outback Imports on the 73 verse 74 thingy, he thinks and feels the 74s are superior also.

Good to hear this feed back.

 

[Radd Cruisers]

Must admit though, the 1HD-T in a 70 series would just plain knock the doors off most anything other than the 1HD-FT.


I absuolutely love the HDJ81, it plain pulls hard from about 1200rpm, what a smooth engine also.

original manifold with custom unit from Bruce he has sitting around in a box. why cheeper than a kit and performed flawlessly. 0-100 in 15 seconds on 35" boots (added propane and dropped the ets to 12 seconds)

Marko feels the 13BT is a superior engine to the 1 HZ?
i would have to say that has little experience with the 1HZ then.
each to their own of course...

 

[lshobie]

I can't see the BJ74 depreciating at all. Like it was said, it's all about supply and demand. I havent seen a decent 74 at the auction in weeks, and great 73's are few and far between as well. Doesnt mean that importers will make more money - just that they willhave to pay more to get them.

Just my opinion.

I'll admit that I have very little experience with the 1HZ but I wonder what makes anybody feel they are superior to the 13BT. Its a good discussion though. They are both very good motors and I'd have a very tough time deciding between a HZJ73 and a BJ74 with similar condition and price.

I think if you poll the mines who had a version of both, they'd prefer the B series motor for its reliability.

1HZ advantages...
- 6 cyl = internally balanced
- More cubes = potential for more power
- provision for gear driven vac and hydro pump
- current motor with 15 years of parts worldwide.


13BT advantages
- direct injected
- inline pump will outlast rotary 2:1
- gear driven valvetrain = no timing belt
- piston spray oiling = higher egts allowed
- adjustable valves with $8 worth of tools
- factory turbo charger and boost compensator
- reliable big end bearings
- precision machined ( no requirement for selection of bearings )

actually i have seen about 4 in the last year that i would even consider bringing in.
the 13BT is a good engine but it is old school. the 1HZ has the 13BT beat hands down. it is quieter, better on fuel, more horse power naturally asperated and almost the same torque readings .5 kg/m less. and it is still in production today.

after taking the 1HZ off road i will put that engine up against ANY 13BT. the torque is smoother and the bottom end grunt is just unbeleivable. you have to drive it to beleive it.

now all this having been said, a low km, mint condition BJ74 will still fetch a premium dollar but the higher km BJ74 units will depreciate much quicker.
this is my opinion and is only based on hunches and watching the market of these trucks as they past from first Canadian hands to second and sometimes already into the 3rd set of hands.
cheers

 

[HZJ60 Guy]

Ya gotta go with ole WayneO. That HZ is an ass kicker. Besides, the guy has around 400 years experience with them. Imagine that engine so quite on some good biodiesel.........


TB

 

[lowenbrau]

400 US years converted to Canadian = 6 years (four of which the engine was in Colorado) and a total of less than 20,000 miles? Wayne is a cool guy and all but he'll be the first to tell you none of us Albertans are 1HZ gurus. If we could get Mike Mctague on here we might have some serieous experience.

 

[crushers]

that is true Bruce, i would be the first to admit i am no guru, i just play around with these things.i have owned and driven hard both the 1HZ and the 13BT. driving a 1HZ for 100,000 miles doesn't make one a guru nor does driving one hard and modifying it.


if you want hands on experience we will need to go to the mines or austrailia.
i would suggest contacting Brian or Mark at ENS Toyota if you want to know what kind of engine the 1HZ, 3B, 1PZ is for abusive conditions. or ask our austrailian brothers for their experience with the 1HZ or 13BT since they put their trucks through torturous testing in their enviroment.

Looks like someone is trying to sell people on a certain engine to me! Good more 13B-Ts for me and my friends.

I know of only one Japanese Land Cruiser owner that wheels a 1HZ and that is only because he wheels a HZJ 73. The rest of my Japanese friends (mainland and Okinawa) consider them as a less desirable Land Cruiser engine (1HZ).

I like the 1HZ but I like my 13B-T a whole lot more. I would choose a BJ 74 over a equal HZJ 73 every time . IMO the BJ 74 is a way more durable offroader than a HZJ 73.

1HZ better fuel economy than a 13B-T? I beg to differ.

1HZ has better low end grunt? Maybe but I will pass every 1HZ equiped cruiser with my 13B-T on steep roads and at altitude.

It is ashame that the 13B-T is out of production.

 

[crushers]

nope, not trying to sell a certain engine at all. the 13BT is a great engine, just dated.
i liked wheeling my "ol smokey" and it booted down the road just fine.
i loved the modified HZJ75.

i dislike those that have never owned a certain engine but saying one is better than the other. i owned, drove and wheeled them both so i was stating how i FELT about the 2 engines.

you stick a turbo on your buddies HZJ73 and then try and pass him on the hills. then you will see why i like the 1HZ, you make that engine come alive with very few bucks. with a 13BT there is very little extra hp you can squeeze out.

i sell what i think fits the customers needs. just because i like the 1HZ does not mean i wouldn't sell a 13BT and it does not mean i wouldn't buy one or drive one myself.

curious as to why you think the BJ74 is "more durable" than the HZJ73?

I stated my opinion in a thread where a question was asked. I do like the 1HZ but I prefer a 13-T. Simple concept, really.

You are right that I have never owned a 1HZ powered cruiser. However, I have driven them on and offroad on many occasions. I have nothing against them. Good motors in general. Not a whole lot of reason to dislike someone over but if you feel that way then fine.

Sticking a turbo on a 1HZ and then comparing it to a 13B-T. Sure that is a hands down no brainer. You got me there. Given a choice of a 1HZ-T and a 13B-T, I would still prefer the 13B-T. If I wanted a turbo on a 6cyl diesel engine then I would have bought a 1HD-T. Again this is just my opinion. What I would do.

Agreed that your not going to squeeze a whole lot more power out of a 13B-T. With a 13B-T you kind of got what you got. I don't have a problem with that. I personally like the 13B-T because it is durable like all "B" engines.

Why do I think the BJ 74 is more durable then a HZJ 73?

IMO I believe the 13B-T to be a rugged engine that can take a lot of offroad abuse. I don't feel that strongly about the 1HZ even though it is a good engine. I don't like the HP reverse cut front 8" front diff on the 73. I would prefer the 9.5" front diff of the 74 for rugged offroading.

Randy,
my comment was worded wrong, my appologies. i did not mean i would dislike a PERSON for not owning both. i have tried to type what i meant but it still comes out wrong...
i have not owned a HZJ73, only a HZJ75 but the drivetrain "should" be the same. so i am in the same boat as you.

i agree, the HP front on the HZ series is a bit of a weak spot but how many have you seen break? i heard that Jeff snapped the front out of the HZJ75 when he owned it and i have just replaced a set of gears in a 81 that had unusual wear. also i do know that the old style front diffs wear damn near bullet proof although i have seen them break as well.

i hope the 13BT isn't like all the other 4 cyl Toyota diesels or it will have head problems as well.

end of my participation in this thread, when i offend it is time to step out.

cheers

Nope. It's a B series...not an L series...

Just food for more thought...

I recently came to know a person here in BC who owns an HZJ75 pickup with a homebrew turbo in it. After meeting for coffee and a chat a couple of months ago, we decided to let each other drive each other's trucks.

First thing I noticed on his HZJ75 (aside from the funny clutch), is that his 1HZ really liked to be spooled up in higher revs before it starts working. He kept on telling me to stick my foot down to it to get it to its power band. Granted, he has the wrong turbo in it right now, and he'll probably change it to a smaller one that doesn't take so much RPMs before it develops adequate boost...but it still seemed to me that the 1HZ likes to work at higher RPMs than my 13B-T.

Did I like the engine? Yes. It is a smooth running and quiet (for a diesel) motor. It is very clean burning, and it is still currently in production.

Would I trade in my 13B-T for one? Most likely not. The 13B-T seems gutsier in low RPMs. In fact, that HZJ75 owner stated that when his turbo 1HZ "packs it in", he'll probably drop a turboed 3B in it to replace it! The only reason why he would go turboed 3B instead of a 13B-T, is because he has about 30 parts rigs in his property that can be put together for a number of good 3Bs, but he would spend lots of money in order to buy a 13B-T. So, in his books at least, he certainly liked the 13B-T more.

 

[denis]

Anybody knows how much heavier the HZ is, compared to 13BT ?

As far as I'm concerned, I went the lightweight way, 2L baby yeah And it actually floats my boat
