they could have added a scrubber ...
Sounds good. Let us know how the PZ handles 30psi boost and what power/torque figures you get from it.
Toyota only sell the 1HZ into africa (because it'll handle the dirtiest fuel) and for some underground mines. That's it. The underground gold mines here are running 4.5 V8 cruisers now.

same reason to drop 12H-T .. was way too good engine ..
The 12HT was replaced with the 1HD-T. Just like the 13BT was replaced with the 14BT, then 15BT/15BFT(E).
Progress I suppose.

umm what stock 13Bt runs 30 lbs of boost?
Hulsty's was. You know, the post you replied to taking up "the challenge". Take 13BT, intercool, fit a G-Turbo and wind up the fuel as far as it will go.
I thought you were going to do the same with the PZ?

responding to:
<Indeed, but you are comparing a seriously modified motor (1HZ with turbo) to a bone stock motor.>
but now you are taking a heavily modified 3B (13BT) and moding it even further to go up against a basic 1HZ with turbo.
that is not a fair challenge at all.
i was will willing to put a lightly modified 1PZ up against a heavily modified 3B (13BT)... but if you feel that isn't a fair challenge then i understand if you want to pass.

They didn't drop it , you retard. They bored it and stroked it and made it into the 15BT. Then they started replacing their 1HDTs in commercial applications with it.
They keep the 1HZ because it is so Wonderbread. It is smooth and cheap and dependable and you can get it anywhere but it doesn't really have much power. Kids love it though.
We have two comparisons.
1. Stock
1HZ/1PZ vs 13BT.
2. Modified turbochargers.
Fit whatever turbo you want to either engine and turn up the fuel to suit.

As much as I love/enjoy ( and own ) 1HD-T .. I can't compare with 12H-T coz it's just such a great engine .. just tip .. timing belt again timing gears ..
to be honest 1HD-T have some upgrades over 12H-T but still .. well anycase as same as 12H-T the 1HD-T it's no longer in production.
Wow I have been skipping past this thread, looks alot more interesting than I thought.
IMO Emissions and NVH, complexity and cost of manufacture are all reasons why the change to 1HZ. The 13BT and derivatives are a more agricultural truck based engine the demands of market refinements would have driven a change to the smoother, quieter 1HZ.

you are missing the point ...
the 13BT is a factory modified 3B
it is only a fair fight if you can modify the PZ as well...
of course you could remove the turbo and make it a 13B ...

Challenge accepted though it will take me a little time to get results (ie few months) car is practically ready though it needs to exhaust extended before I hit the dyno and have it properly tuned.
I have briefly run 30psi through my stock 13BT, mods are GT26, small W/A intercooler and 3'' exahust with fuel pump set to maximum, now it peaks at 25psi daily, not enough fuel to take advantage of 30psi.
I am unclear what you are talking about here? with this line "heavily modified 3B (13BT)" ?
FYI I have had a back to back comparison between my BJ74 and a mates bitsa landcruiser 1HZ. His car has 118rwkw from a Garret 2876R, W/A intercooler, same gearbox and diff ratios as mine, though he runs ~33'' tyres and me 35'' tyres.
My impressions are that the 1HZ had less bottom end torque (turbo is a factor) and built boost slower than my GT26, it definitely felt like it had more of a top end rush than my 13BT which can be a factor of the turbo selection and the fact I could rev it to 5000rpm, 13BT stops at 4100rpm.
I am very keen to get my 13BT onto the dyno when funds, time etc allow, I suspect it has around 100kw (could be a bad guess) at the wheels, but very good torque. A recent comment from another mate, following me on a winding tar road 80-100km/h in his 150rwkw TD42, was that my car was F*CKING FLYING ALONG!! I had a good laugh I thought his would have flow past me.
In the interest of political correctness "retard" has been replaced by
"mentally challenged"
just like you are no longer fat you are just "gravity enhanced."

a 13BT is basically a 3B with direct injection head and turbo, is it not? that would make the 13BT a heavily modified 3B.
so,
a 3B is 3431 cc
a PZ is 3469 cc
close enough for a fair comparison.
the 13BT is a modified 3B with direct injection and turbo.
to be a fair fight the PZ will be turbo'd.
according to Dougal, the DI engine with a turbo is the cat's ass when it comes to performance and fuel economy.
i am saying an IDI engine with a turbo added will return better fuel economy and better performance.
that is the challenge. stock 13BT against a PZ+T.
of course this is all mute since it would never happen.

Your sounding like a politician, saying one thing, then when it comes down to the crunch duck shoving around the issue and pulling every excuse in the book.
A 3B is a 3B, 13BT is a 13BT stock and stock, to me, what your saying is like also saying a 1HZ is a heavily modifed 2H, both a 6cyl IDI diesels, just different block, pump, etc etc.
So your now pulling and and down want to play shoving 25-30psi into a 1PZ to see how it goes ?

nah, i can see that you don't agree the 13BT is a modified 3B.
at that point this discussion becomes irrelevant.
i want to see how your 30 psi holds up over the long term.

Yeah it's a 3B with completely different pistons, head, injection system and turbo.
Good, lets see your 30psi and resulting figures. Of course we used an enhanced turbo, but for fairness the PZ can be fitted with the same model.
The 13BT side has been done. Your turn.
