Great video. You should include more videos like this, especially with mechanical diesel engines with a boost compensator. Would like to see how much more power and torque that can be gained with a proper tune on the dyno.
Had to google what the hell a 1PZ engine was. Man, only 85kW at the crank from a 3.5l engine is piss weak, i guess that's NA diesels for ya. But it does sound really nice.
Its definitely no race car ! I also had no idea toyota made a 5 cylinder diesel till this thing showed up. have to agree on the sound, is the best thing about it
I always wanted to see one of those big, old diesels with compressor, for example unit from Merc 1.8L, 2.3L or 3.2V6. Installation shoud be easier than with turbo, no lag, instant response, lower intake temperature. Think about it :)
Seems like a pretty good match to me. whole power curve is bumped up. doesn't fall away up top. works well with stock un-compensated pump. said injector pump will be the limit rather than the turbo.
Hello from Norwegian living in Brazil. Next week Im off to Amazonas to buy a 1992 Landcruiser 75 with the 1PZ engine. (Maybe the only one in Brazil). Great to see your video since I need to turbo/intercool it. You know your stuff! The 2560 you tested out, was journal bearings or ball bearings? If it was for yourself, wich size of turbo would you use for early spool/torque? I need a mentor for my build. Is it possible to contact you private trough UA-cam? I will of course pay for the information. I will need to purchase lift and Australia is the place for this. Regards, Chris
That turbo was a really good match for a mild setup. even on the uncompensated injector pump was very little smoke low down. would have been more in it with more boost more fuel and an intercooler. turbo is ball bearing. factory turbo off a s15 nissan silvia
@@Garage4age Thank you for your reply. Sorry I missed that graph. If you had turned up the boost to the double. Would the graph showing torque be higher from 1650rpm already or will it come further out in the rpm range?
@@cga3067 yeah probably. Depends on fueling also. Unsure what the stock injector pump is good for. The guy that owns the truck just wanted it to go bit better up hills and the likes
I would run a intercooler if it were mine. but this simple setup should have a bit more in it. maybe a little bit more fuel and boost when clutch fixed
Yeah, It would have showed a bit more power on the dyno with some smaller road tyres, run up in 4th gear. Was more interested in the comparison rather than the numbers, so the low speed 3rd gear runs are fine
Probably. Was basically at the point were it needed more boost before adding more fuel. as owner didn't want to be smokey. but clutch issues. owner was happy with how it went after fixing clutch. so it hasn't come back for more.
Only fuel. Will have a bit more left in it with more adjustments. but will need at least a clutch first. its not doing too bad for stock uncompensated injector pump.
from what i can tell, the "1PZ" engine is the same as the "1HZ" just missing a cylinder. so yeh obviously the 1hz will make a small amount more power. but otherwise i wouldn't be too worried either way
Its only just getting enough fuel into it for the little boost its running. Got to get that balance right, May try for more fuel and boost if the owner wants more, once clutch fixed
@@moonbrothers9098 compensator wont give any more fuel over what the injector pump can supply without it. they are more there to take away the excess fuel when engine is off boost. This one is a pretty mild setup and turbo comes on boost early. so doesn't really have overfueling issue with the non compensated pump.
@@Garage4age Really My 1pz is running 20lbs and the difference between having a boost comp and not was life changing? Im desperate to put it on a dyno and give it a proper tune. do you have a contact?
I can assume that's a mechanical fuel pump with no boost reference? So you're able to get "power smoke" if you floor it too fast before it's up on boost? Wuld hav been interesting to see how much power you could have get out of it before the turbo just by adjusting the fuel 🤔 of course the egt is much safer with extra air but still would have been a nice thing to try out
You guys across the pond have all the cool toys! Great video 👍
They’re not in England
Great video. You should include more videos like this, especially with mechanical diesel engines with a boost compensator. Would like to see how much more power and torque that can be gained with a proper tune on the dyno.
Its interesting seeing someone doing diesel tuning
a bit of timing on the pump would probably help a decent amount as well. nice work!
Awesome video mate. Was just looking at buying a PZJ70 today and the plans to turbo it. Anymore of this truck would be wicked
sweet, will do if it comes back after clutch is fixed
Next try the baby cones.. You know those little ones. lol🤷♂️

How much tourqe tho? Its a diesel
@@Garage4age I always have loved the toyota diesel engine sounds 👌 😍
@@stanley4290 a measly 230 Nm
edit: stock at the crank
@@poptartmcjelly7054 damn thats not much, if i would compare to my 2005 passat ist a 100less
congratulations! need a mac truck dog on front
That's pretty straight old cruiser hard to find them like that these days
such a good video in 4:22 minutes!!

BTW thank You for video!
Great job, as usual.
Venezuelan model 1fz fe 4.5 engine.... Good sound..... Good torque

Would've thought the exhaust housing be a bit small for that engine

leaning out hard..put a boost compensator on, then you will see how hard these go!

@@Garage4age Thank you.
How many bar was the pressure on these runs?
@@cga3067 it's in the graphs in psi
@@Garage4age Thank you for your reply. Sorry I missed that graph.

Next video "how much psi does it take to send a rod out the block " 🤔
maybe this one should have been called how much psi till the clutch slips
Don't think diesel cares as long as EGTs and RPM within acceptable limits. It's too much fuel that'll kill it, not boost.

Intercooler next with an up graded clutch?
I would run a intercooler if it were mine. but this simple setup should have a bit more in it. maybe a little bit more fuel and boost when clutch fixed

Little surprised you didn't do a wheel swap for the dyno.
Yeah, It would have showed a bit more power on the dyno with some smaller road tyres, run up in 4th gear. Was more interested in the comparison rather than the numbers, so the low speed 3rd gear runs are fine
@@Garage4age fair enough sounds bloody good though.

Hey man, where did you get the oil feed and drain from/to? Cheers
used a double banjo on the vac pump oil feed. and welded fitting to sump.
@@Garage4age oh awesome man cheers for that
Surely it couldve benefitted from a mild boost increase, say 10psi total ?
Probably. Was basically at the point were it needed more boost before adding more fuel. as owner didn't want to be smokey. but clutch issues. owner was happy with how it went after fixing clutch. so it hasn't come back for more.
Christina Shoals
Why does that 12mm flange suspiciously look like two bits of 6mm welded together?
Ha ha, you said flange.
What turbo kits you used ?
How much it cost if i put turbo in 1pz
And how much the EGT raise up? :P

No timing adjustment?
Only fuel. Will have a bit more left in it with more adjustments. but will need at least a clutch first. its not doing too bad for stock uncompensated injector pump.

You should think at motor swapping, we expect much more from you, Lol
That was sick.
Imagine if it had an extra piston.🙂

i found a PZJ75 for sale. car look decent but more focused on motor. Is the PZJ75 worth buying or should i just buy the HZJ75?
from what i can tell, the "1PZ" engine is the same as the "1HZ" just missing a cylinder. so yeh obviously the 1hz will make a small amount more power. but otherwise i wouldn't be too worried either way
@@Garage4age thanks man.
More boost is needed
Its only just getting enough fuel into it for the little boost its running. Got to get that balance right, May try for more fuel and boost if the owner wants more, once clutch fixed
@@Garage4age You have to run a boost compensater... It will never get enough fuel otherwise

Weird looking 4age but ok?
such a sellout

Sell me this cruiser?
Not mine to sell !
what are the "Turns" you are revering too ?
