Cool thread. Can't wait to see what you end up with the roof tent and turbo.

Thanks for the input. I was wondering if it would overwhelm the DOC eventually.
I guess it's not like a gasoline Cat, which might last forever if you keep your engine tuned.
I kept waiting and waiting for the original cat on my 4runner to die so I could get a modern higher flow one and do a cat back exhaust, but it just wouldn't. I eventually gave up and replaced it after 34 years and 270,000 miles (and I am keeping it as a spare!).
I've been researching turbos and I am leaning towards an HX30. I'm looking to help with maintaining hill and freeway speed, and also clean it up a bit.
I'm planning on doing the flipped stock manifold, a top mounted intercooler and 2.5" exhaust at the same time.
From the various posts I found on Mud, the 44mm HX30 is the correct one for the application?
I'm looking at you @GLTHFJ60

Get a great deal on the popular HX30 turbo with a 44mm compressor wheel!www.benzforce.com
Should be pretty close, but these turbos can produce a ****in ton of boost with enough RPM. I'm not sure how much your engine can hold.
The 46mm inducer "super" hx30 is what I have had for years. They make 40mm inducer all the way up to 46mm in the same frame size, so if you want one that's bigger or smaller it's a bolt-in affair more or less.

The general consensus for the 2H is less than a ****in ton of boost. I should be able to control that with the wastegate (right?) and I need a blowoff valve anyway since the 2H is weird and has a throttle plate.
This is my first foray into Turbos so any and all help is appreciated!
I have seen plenty of turbos fitted to 2Hs in Australia.. I have never seen a blowoff valve fitted.
I can tell you all about tuning and whatnot with turbo diesels, but turbo selection is very engine specific. Most of the 2H turbo setups I've seen on here use a CT26.
You can control overall boost with the internal wastegate yes, up till a point. Too small of a turbo and you won't be able to pass enough exhaust through the wastegate to control boost. Conversely, too large of a turbo and it won't "light" till too high of an RPM and it'll annoy you.
You have to do the turbo selection research yourself. I'm not familiar enough with the toy diesels to recommend anything.

Interesting. I guess boost and power is low enough not to cause surge problems from the throttle closing?
My diesel mechanic friends thought I might need one, but they are used to big diesels: Cummins, Caterpillars, Detroits (real ones, not the gm 6.2 lol). And also gasoline V8's in their muscle cars.

The sign shop finished my roof panel. Everything lined up and it installed without much difficulty.
I was also recommended some light reading material:

This week I made a box for the Altimeter/Thermometer that is more up and out of the way.

I took my mom out to see the wild flowers for Mother's day. Lots of Owl's Clover, Paintbrush, lots of things I don't know the names of, and one Yucca spike starting to bloom. There was also one white Owl's Clover among the zillions of purple ones.
Happy Mother's Day to all the Mudder Mothers and Mothers of Mudders!

What are people's opinions on Kinugawa Turbo's?

It followed me home! Can I keep it?!
This 2H popped up on craigslist somewhat locally so I went and nabbed it as a spare. It's supposedly from an HJ60 from Canada that had 386,661 km's before it rotted out and got chopped up (It came with a gauge cluster). It has been sitting for awhile but I was able turn the crank by hand until I hit a compression stroke. It's from an automatic truck so the injection pump has a different governor.
@duncanrm is there any advantage to running the governor off of the automatic truck vs the pneumatic governor?
It also came with the automatic transmission, vacuum shift transfer case and an assortment of bits and bobs that I hope to pass on to other cruiser heads.

I cant think of any advantage that this pump offers.. I am unsure what the implications of running it on a manual are, its an interesting question!

On the auto tranny 2H, it looks like the "throttle plate" is only used for engine shutdown, activated by a diaphragm with a VSV. The governor appears to have a manual stop lever on the side as well. If so, the engine could be shutdown with a pull stop cable and the "throttle plate" could be removed for slightly better air flow. This seems like it would suit a turbo build.
It would also remove the diaphragm as a maintenance item, but I don't know if that is a big deal since I haven't done mine, or if it adds another maintenance item elsewhere.
I understand the 2H Auto pump and throttle body are pretty much the same as the 12HT. A stop cable can work on the 12HT pump so you're all good there.

Thanks! This is me thinking far (hopefully) into the future. Harumi only has 270,000 Km's on her so the 2H that's in there should last awhile longer.

Nice to have spares. Oil pan etc etc. 
Fantastic write up. I know the time it takes to take pics, post them, write about them and all that. Thats why I never do it.

For the more complex pieces (like your overhead gauge pod)....is that cut at 'work'?
Did you design and extrude the tent mounting walls?
What are you using to sand and smooth all of those welds? Especially in the corners/hard to reach areas?
What are you doing for the underside of all the welded areas? Some places you can't paint after closing them up.
