looks nice. whats the extra pipe there on the air intake hose by the air filter housing for?

I did not read the whole topic, but I would like to clarify that you monitor the turbo diesel in the following way:
(just skipping any questions all the precautions, only about monitoring for now)
- EGT measurement by pyrometer gauge somewhere on exhaust manifold or where it mates to the turbo
- Same kind of pyrometer somewhere on the engine head?
Can I use these kind of devices to measure that? They have the right range, and can be connected under some existing bolt.

- Monitor oil temp?
- And a more precise coolant temp measurement I understand. Although I must say, the original one is responding very fast (don't ask me how I know haha something with a bad radiator cap)
Now on the precautions. I have a snorkel, and the air intake/filter is separated from the engine room, so that is nice.
I guess that an intercooler would also help. Or am I overestimating it?
Next to that, would an oil cooler help? And where in line would you place it? On oil return line coming from the turbo?
Thanks I’m pretty stoked with it!
Is this what your refering to? (Picture below)
Cause I have no idea I got it like that haha should I delete it?
Cheers

ja, that. only reason i ask is bc it looks like the end is open to the air? there fore rendering the air filter useless?
although im still new to the 2L-TE, i do have a lot of experience with other diesels, and i would not personally be using a thermocouple like that. all thats going to do is give you the temp of what ever bolt you have it under. you want to know what the coolant temp is. so you want a thermocouple that goes into the coolant galleries, or the thermostat housing, or the rad housing.
same thing with the EGT thermocouple, you want it in the exhaust, either pre or post turbo, not just bolted to the outside. its not going to give you a true reading of what you want
also, a oil cooler is going to cool your oil, not your coolant or head.
an intercooler is always a great thing on any diesel engine, especially a turbo.
I have a pre-turbo EGT gauge on my Chevy 6.5TD. I installed the sensor myself, using a place on the exhaust manifold I could reach with my drill.
First, I chose a drill bit sized for the threaded adapter for the EGT probe. Then, with a cold motor, I drilled what I estimated to be almost through the cast iron of the exhaust manifold. Next, using a bit of grease on the tip of the drill to catch metal bits on the tip, I started the motor. This pressurized the exhaust manifold with exhaust gas, and blew out any extra metal bits. I had the tap ready to use as soon as the hole was drilled, and the manifold wasn't very warm yet. I then tapped the hole for threads for the probe, using the exhaust pressure from the running motor and grease on the tap to catch any metal particles before they could possibly go into the turbo.
Using this method I was able to successfully drill and tap the exhaust manifold without removing it, or getting any metal particles in the turbo. I hope this helps you.

Hi Guys
I am new to the forums and landcruisers! I have just purchased a 1992 LJ78 Landcruiser Prado EX for work
I will add some photos below. The truck is a fresh jap import super tidy inside and out with a verified 110,000km on the clock.
I am wondering what you guys think my first upgrades/mods should be to the 2L-TE
?
I am thinking I will add a K&N Air Filter, does anyone know the exact one I need for an LJ78?
Also thinking of swapping out the factory exhaust pipe with a 2.5inch one
I want to add the proper gauges to monitor this ( water temp, exhaust gas temp and maybe boost gauge?)
After reading some of the other threads/forum I am thinking about putting in a Air to Water intercooler as well.
Don't have a lot of money currently to spend on upgrade/mods atm but what would the first couple of things you guys recommend doing to counter the overheating issues with the 2L-TE?
Much appreciated
Joe
That tube is probably sealed on the end, and used for tuning out a resonant frequency/wave or something along those lines.
Thanks for the advice!
I was wondering what you would say your number one best upgrade/mod would if you could only do one thing?
I think I will remove that tube too and am looking for a manual boost controller for tuning.
What is the EGR system and how to I get rid of it?
Thanks for you help
Joe
EGR stands for Exhaust Gas Recirculation; the system pumps a certain amount of the exhaust back into the intake to re-burn it to reduce emissions. It is very easy to remove/disable, and I would recommend it highly, as there is almost no cost but time. I posted some photos when I did mine, about halfway down the first page here: 1990 LJ78 in Montana
Wow that is interesting. I have heard from and spoken to a number of people who are always telling me to put a K&N into my truck haha
Thanks for the feedback on the EGT sensor.
So this means that such a unit would be good to insert into the manifold? (by tapping a hole)

I don't have any feeling for the quality of these kind of things, but this one would do the job it seems. I'm listing what is needed so I have an idea of the cost involved in the modifications.
I have no idea the quality of the one you posted, but an EGT probe isn't something I'd shop for based on price alone. If the tip breaks off and goes through your turbo, you'll wish you'd spent the extra $30 or so on a quality one, lol.
