Re: 4.2 Turbo or not ???

As far as I know, and I'm pretty damn sure about this, but the station wagon NEVER came out to SA in a 4.2 with Nissan factory turbo only a N/A TD42 ( TD42 ). Only the Pick Up came out with a factory fitted turbo ( TD42Ti). They stopped producing/supplying South Africa the TD42 stationwagon end of 1999. So it may be that that one is a 1998 or 1999, but only registered in 2000. Prior to 1998 was only the GQ model with a TD42 motor (TD42).

That will definitively be an aftermarket turbo and Intercooler.

Take a pic of the Injector pump too if possible. That will also ensure the pump has the compensator on to deliver the correct fuel for the turbo's demands.

Does it have an EGT gauge fitted? I would be cautious if one is NOT fitted. The aftermarket turbos do push high EGT's and that can cause issues even to the legendary bullet proof TD42 motor.

Re: 4.2 Turbo or not ???

Def not a factory setup
The thin pipe on the thermostat housing is leading to the turbo for cooling. This means its not a Nissan turbo to start with as they are not water cooled.
Intercooler is also not a TD42 cooler like on the pickups.

Can be a nice buy if all is well on it.

As Cedric said, take a pic of the diesel pump as it will give an indication on the tipe of conversion done

Re: 4.2 Turbo or not ???

Same intercooler that I have, and my car also (originally) had a water-cooled turbo.

My guess is that you're looking at an Alpine turbo kit...

Re: 4.2 Turbo or not ???

Dustin, Maybe you can get hold of Frans ( tour de Frans on the forum), He is the TD42 guru in the Cape in my opinion, and he has worked on my Patrol. maybe you can make an arrangement with him to have a look at the Patrol.

As for the top mount IC, I wouldn't stress too much about spending unnecessary money for a system that does work..... he will be able to service and set it up properly for you.

Tell him Cedric told you to get hold of him. He is a really lekker genuine straight up guy !!

Re: Turbo charging a TD42 engine


Tinus, you talk about an "Aneroid" fitted to the diesel pump. What is that exactly ?

Here is a link to give you an explenation of exactly what the aneroid/boost compensator does.
But in short it mechanically gives more fuel to match the more air that is being forced into the engine via the turbo

Re: Turbo charging a TD42 engine

You'll also be fine without the boost compensator (an "aneroid" really sounds like something you should be taking pills for!)...

The problem when tuning the engine without an android is that the diesel pump won't increase it's delivery according to the boost level (which is what you want), so you have to optimise the pump delivery for either on-boost or off-boost. Obviously you'll adjust it for on-boost fueling, which means that the pump will supply too much fuel when the turbo is off-boost. That causes momentary over-fueling, resulting in some smoke when pulling away briskly.

Because the puff of smoke is always behind me (unless I storm off in reverse gear!) and it only happens for a brief moment, I am very happy to save the money I would have spent on an android and rather spend it on nice set of tires, a fridge/freezer, or something for my wife (how did this end at the back of the sentence?). As you may have guessed by now my TD42 does not have a hemorrhoid...

PS: This is a problem that only afflicts the old TD42 engines. The later engines had an ECU that controlled the fuel delivery based on air-flow, accelerator pedal position, engine temperature, phase of the moon, etc. It also took all the fun out of endlessly fussing with the fuel screw on the diesel pump :lol:

PPS: Inter-coolers cool the turbo-charged air down, allowing for higher boost than without them (yes, please!), and for increased engine life (cold air is less likely to result in detonation, overheating, etc.).

PPPS: There's no need to worry about blow-off valves for your turbo on the TD42 engine, because the engine does not have a butterfly valve on the intake manifold. As a result there is never a chance of boost building up (like it would on a petrol engine when you release the pedal), unless the engine stalls. Boost level is controlled by the turbo's wastegate, and that is controlled only via the wastegate actuator. Unless you drive a 3.0 diesel, in which case the ECU gets involved big time in controlling boost levels...

Re: Turbo charging a TD42 engine

Dustin, I would write down all I know on the black top vs silver top, but it would take ages..... :rolling: :rolling:

Have a look at this here.... pretty much covers it. But in a nutshell, it seems the GU TD42 motors we got were a bit of a mix of bits and pieces of both. whereas the GQ or Y60 model TD42 that managed to get into SA were the pure silver top.

Re: Turbo charging a TD42 engine

Dustin, the TD42 never had a common rail version

The factory pump also never had a boost compensator (as far as my knowledge), but rather a altitude compensator (which is useless) so that price is a bit steep because it will cost another 7k - 8k to get the pump reconditioned and modded to have a boost compensator.
Then 4k for a cooler is way too much, you can get a bigger and better top mount cooler new for cheaper than that
Turbo isn't bad, but again you can buy a brand new better suited turbo for thr TD42 for less than 6k.

Then on the ECU, this I am not sure exactly what it controls, but ist defiantly not the fueling nor the turbo as they all have normal waste gate turbo's.
I think it mainly works the EGR system and adjusts the pump timing only.......not the fueling as it is still a mechanical pump and they do not have a MAF. This is why the pump is too expensive as that system is not great and I have the diesel shops make the pumps 100% manual again.....just works better :thumbup:

Re: Camping trailer

Cedric, I am sure in some cases it will trip you up, while in others it will save your bacon. Imagine your trailer coming un-hitched while you are on your way down Van Zyl's, with lots of guys standing around trying to tell you where to drive?

Dustin, sounds like this was years ago, and the other party never actually went into production? If so, you can make it, because a patent lapses if the item is not in production within 18 months of the patent being granted...

TD42 Turbo Manifolds

Gents

There are quite a number of people looking to turbo their N/A TD42 and the biggest problem at this stage is the manifold availability and price.

The second hand ones are very scares and at the moment there are not any available as I am looking for one. New they cost around R8,000 from Nissan and I think that is just too much money to pay for a manifold.

One option is that we can get new ones "casted" and machined for half the price.

Who would be interested in going this route, the more we order the cheaper it will get so I recon we should get away for between R3,000 and R4,000 for a manifold.

Re: Diesel lubrication additive

Dustin

As far as I know 50ppm and 10ppm diesel are produced for emission purposes and nothing else. It is true that the sulphur aids as a lubricating agent in the old school pumps, but this matter has also been discussed a lot on many other forums.

It seems like the majority of old school oil burners add 2-strole oil to the diesel as the best additive. I have used it a couple of times, but not on a regular basis. Not sure what the effect the 50ppm really has on the pump.

I try to use 50ppm instead of 10ppm but not really fussy on what I throw in. We rarely find 500ppm in Gauteng these days.

Re: Diesel lubrication additive

Sasol has the 10ppm diesel. Luckily our old school motors can run with just about anything. I use the Castrol diesel ( 50ppm ) cause it was R11,28 a litre, and I have been filling up there for years now. Every now and again, I add 200 - 300ml of 2 stroke oil into the diesel tank. Does it do any good, does it do any damage..... who knows and who cares.... Its an unending debate !

What I can tell you is that it makes my motor run a LOT quieter. That typical diesel chunk chunk is definitively quieter. I used to even put 100ml into my SANI 3.0 V6 every 3rd or so tank full of petrol. It, in my mind, made that motor sound healthier. I also had an Isuzu 280 turbo diesel that I sold with over 500 000Km on, with its original turbo and un opened motor. Was it due to good regular servicing or the 2 stroke or a combination of all 2 ..... I don't know, but in my opinion it does make a difference. I was also told to rather use marine 2 stroke instead of normal 2 stroke, but as marine 2 stroke is a lot more expensive that normal 2 stroke, and my wallet is not looking very healthy, I have been using normal 2 stroke for about 8 months and the Iron Maiden still sounds very healthy !!

Re: The "Moose Test" - Will your rig pass it?

Dustin, I'm not knocking these deer whistles, but I did some research on them on the internet a few years ago, after a near hit with a cow on the Jozini road up to Kozi Bay. The information that I landed up getting was not very positive. But I do suppose having something is better that having nothing, so hence why I say I'm not knocking the product.

Have a read through this as it gives a little info about the deer whistles. The tests were based overseas but I was more concerned about the results. I assume dogs, goats, donkeys( even though they are as thick as pig sheeeet ) and various other animals hear in different ranges, it was still an interesting read....

Re: My '98 GU 4.2D

Dustin i had a k+n filter inside my aircleaner on my 4.8....worked amazing until you smell a bit of dust and that was it blocked .....had to clean every 1000km on tar even ....
The donaldson tipe filter that comes with the 3l and 4.2 out standard works Michael makes 180kw and 500nm with that one ....it fits and snorkel lines up ......my 2 cents worth :mytwocents:
