what is this doing under my bonnet?

[the monstrosity]

Hello to all on this great site,
The cruiser is a 1981 hj47 tray top engine is 2h, all the rest is a mystery.
there is a power steering unit fitted and this turbo thingy that only whistles when changing through gears.
I read in the forums about many things about turbos like boost, intake even chips???? this has NO attached anything just as u see in the pics.
The engine was a reconditioned long motor 137k's ago
Will be using this cruiser to drag a 1.3 tonn caravan around australia for next 3 months...............here's the question

1.will it increase fuel consumption?
2. will it shorten my motor's life?
3. looks like a real backyard installation..........the exhaust manifold has been turned upside down and the turbo welded to what was the exhaust outlet/flange
4. the plate attached says "Schwitzer"
5. there's an oil leak when the circular metal band holds it all together........seems an expensive repair

do i rip it off pronto ??????????? don't reckon there's theres been any techo considerations involved in installation
regards to all 4 the new year.

#1 Yes
#2 Yes
#3 Yes it does
#4 Ok
#5 that not good at all
#6 I would........

 

[RPM1135]

Does it make good power? I'd start with a compression check to get the whole picture and then for sure rip-that stuff off pronto no matter what!

 

[the monstrosity]

thx grant and RPM

just bought the beast last week from a 'roo' shooter in the wheat belt in west aussie, reckon he might have saved bullets and just run them over with that bar attached.
the unit goes well with plenty of rattling sounds ha ha do you think i could just crimp that oil line off where it comes from the filter ??? wonder if i could find a plug.

 

[grant5127]

I'd plug it Man, if something were to happen to a crimp off job, your livelihood would be spewed onto the ground at a very fast rate.........

I've always had a fancy for the frontal protection you folks come up with...... that thing is cool.......

Kinda sends out a message: We don't swerve or slowdown for anything, We just run the BITCHES over........

I like that........

Well, maybe I'm missing something, but why are you guys recommending tearing it off? In most of the diesel literature i read, -I'm a bit of a diesel hot rodder and coniseur; most of my sources are american diesel publications- if a turbo is done right, it can not only give you more power which in turn can give you better mpg (if your foot isn't in it all the time), but can also help to lower your EGTs (Exhaust Gas Temps). Granted it can be very detrimental to your motor if allowed to create to much boost, but with a good waste gate, that is not a danger if it is set to blow off excess boost at reasonable levels. But again, maybe I am missing something...

HOKIE ASS fab job and it has problems...........

 

[twoturtlesracing]

Another quick thought- if I understand you correctly... If that oil line goes to the turbo, and you plug it off, you will, in very short order, sieze your turbo and who knows what all the damage that would cause. If you're dead set on getting rid of it, I imagine that there is someone that would be interested in paying you for it. Shoot, if I was closer- I might even be interested in it!

HOKIE........

That air cleaner leaves a lot to be desired.........

I love turbos on diesels. Turbo is to diesel what key is to lock.

But THAT turbo setup is kind of lame. Here are the problems I see:

• The oil leak. This is the dangerous part for your engine. This MUST be fixed.
• The air filter looks lame. I bet it is more sieve than filter.
• It is a generally booty-fab job. But that fact doesn't otherwise indicate that it will damage anything (just the two points above)

The turbo is welded to the manifold? That's lame, but not necessarily a deal killer. A flipped 2H manifold is pretty common for a turbo, but if it's welded then you've got a problem fixing that oil leak.

If it were my truck, I'd redo it, but if I could fix the oil leak quickly, then I'd probably run it as it is until you get a good turbo setup put on there. Don't just pinch the oil line, because you will cause the turbo to seize and the motor will barely run that way, if at all. If you can't fix the leak, then I'd pull the whole thing off and drive it normally aspirated. It's better than killing your motor or stranding youself somewhere scary.

I might suggest getting this moved to the diesel section. Lots more 2H/turbo experience in there.

Whats behind door #5........

What kind of problems?

Depending on the owners abilities and or cash flow to pay to get it fixed, plus parts availability might be enough to kill the deal........

Ive seen turbo setups more hokier than that and have run for hundreds of thousand kms
Fix the oil leak you must have oil to the turbo and put on a Donaldson filter or the OEM filter.

Dan,

You are my kind of man! I love diesels! Btw, I was checking out your FJ45 and it looked liked one I stopped to look at a little ways out of ABQ here a while ago... I stopped and asked the guy if he'd be interested in selling it, and he said no. If it was yours, now I understand! If not, there's still hope. I'm going to stop every so often and ask the guy if he'll sell it. Maybe one of these days he'll decide he doesn't want me to bug him any more and he'll sell it to me!

I understand what you're saying about the air filter not being in a good spot, but that could be remedied. As far as the air filter goes, it looks very similar to some K&N, Donaldson, and AEM filters that I have seen? If so, it probably filters at least as good as stock- while moving more air- and is probably a reusable filter which, I would think on an expedition style rig, would be a good thing?

 

[grant5127]

That turbo sits up so high in the bay I'm surprised the bonnet isn't scorched.........

He stated ....... "Will be using this cruiser to drag a 1.3 ton caravan around Australia for next 3 months."

Can you imagine that air cleaner providing adequate protection trudging the back roads of OZ ?

I don't, looks more suited for one of those low rider fast & furious civics.......

I would think a sealed filter and snorkel with a pre-cleaner on top would be in order.........

Besides, I don't believe that setup has been used much as it sits, everything is too clean plus the outlet pipe at the turbo shows no discolor..........

Wasn't me. I bought my HJ-45, trailered it home and it has been behind a locked gate at our shop for the past two years (not getting enough love--soon though...)

I understand what you're saying about the air filter not being in a good spot, but that could be remedied.

K&N is not an upgrade in filtration, if you ask me. I run stock Toyota paper filters in the faux-lux, and Donaldson in everything else. Here is how I think the filter setup SHOULD be done (to add to Coolerman's link, and because I feel so strongly that this is "right" that I did it--this is my Dad's 40).



Those are on a 3B, so the turbo is on the other side of the truck from his 2H. But here's a common way to mount a quality air filter to a 40... This would be pretty easy to do for his truck. It would also be super easy to add a snorkel to this setup.


The Donaldson filters have cyclonic air flow that acts as a centrifugal dirt separator and causes the dirt and dust to collect/fall out at the bottom of the filter before it even gets to the paper filter. The Toyota filters do a little bit of that, but not to near the same degree. Either way, a cone filter doesn't do ANY of that, and probably has oils and junk on it that will just congeal when they meet the dust.

I agree 150% Coolerman! That is a beautiful job that AWL_TEQ is doing. The man has an eye for detail with a skill set to back it up obviously. Very, very, nice work!

1. Sorry Dan, I wasn't paying the attention I should have been when I typed that. I knew yours was an HJ45 but was thinking about the one I had looked at which I think was an FJ.


2. Maybe not. You are probably right. Now that you mention it I seem to remember reading some of the actual test results with K&N and factory filters and yes, you got more airflow with the K&N, but at the cost of filtration capability.


3. Good filters. I run there oil filters and Amsoil synthetic on my Cummins...

 

[grant5127]

but with a good waste gate,

Waste gate?

Me no see.......

Damn, this thread just died out.....

Hoping to get more controversy.........

Open this: any defunk? turbo boost against "butterfly vacuum/pressure" fuel controlled type injection pump?

 

[wesintl]

fix the oil leak and run that biotch. air filter does the job. Fix it or not who cares. A roo shooter drove that thing all over the dust so if it isn't toast by now I'd not worry bout it. It may look hokie but I'm generally function over form. Pleanty of people flip the manifold to turbo these old beasts.
