I'm sure you can find someone willing to swap their HZ engine for your HD-T.
From what I understand there aren't any factory turbo IDI engines from Toyota, is this corrrect? My best option is a 1HZ and install a turbo? Would this be a direct bolt in to my FZJ80 like the 1HD-T? Where could I find one?

You are better off getting a 1HD T.
1KZ-TE was their only respectable IDI turbo engine.
The L series and C series aren't really worth swapping into anything.
I am at a standstill right now. I have sold my 6.2 diesel Land Cruiser thinking I was going to convert my 97 FZJ80 with the same, then I found 1HD-T for about the same price it is going to cost me to go with the 6.2 so I started thinking about that. Then I came across a 1994 Mercedes G350DT (turbo diesel and the absolute best for WVO) for not a whole lot more than I will have in 97 FZJ80 after the conversion. I made an offer on the G Wagon and the seller accepted it but now seems to getting a bit wishy washy on the deal. I sent him a deposit and he says the deal is still going to go through but I think he may be having second thoughts about selling so cheap. So now while waiting on the out come of the G Wagon I am thinking about my options with my 97. I am going to try to get a commitment on the G Wagon this week, if not I will buy the 1HD-T add injector line heaters and a heated fuel filter and run a thinner WVO blend than I do with the IDI 6.2.
Decisions, decisions!

From what I have read, the G350 is a bad diesel, I think they had head issues. If you want a good diesel G you want a later version one that came after the G350, I am asuming that this is a 90's vintage one?

i was looking into a Gwagon for the wife a couple years ago and after some research i walked...

The 350 is the bad diesel. This one has had the engine rebuilt but he has had all kinds of problems with it even since then. He (mainly his wife) is tired of dealing with it. Right now it has a smoking issue at start-up. He is having the IP checked (it was rebuilt) and a compression and leak down test done this week. After the results of this test we will finalize the price. The problems with these engines was they took the 3.0L engine and stroked it to a 3.5L. Turns out they stroked it too much and it caused problems like bending rods and ovalizing cylinder bores. Nothing catastrophic happens to the engines they just don't last, average is about 100,000 miles before they start burning oil etc (even with the bent rods) They now have stronger rods, heads, head gaskets etc that somewhat solved the problems but still not up to Mercedes standards so they stopped using the engine after only about 2 years and went back to the 3.0 liter.
I think the problem with this particular vehicle is just mechanic errors. He has spent the past 6 months repairing things the rebuilder should have done.
I realize I am taking a chance with it but after speaking with the seller and the current mechanic I think it is going to be ok.
As far as expensive to own, this one is a 94, pre electronics so I can do most all of the repairs myself. The engines are 20 years old and in junk yards everywhere so parts are cheap for them. In fact I found a good 3.0 liter engine I am going to eventually swap in for $300. My plan is to go through this engine and when I start having problems I will swap it in.
I originally looked for a diesel G Wagon before converting my Land Cruiser and found out the non turbo diesels are incredibly slow and nearly impossible to find. The factory turbos are impossible to find, there are only 3 300TD's in the country and 3 of the 350TD's that I am buying, so as far as looking for another one it isn't going to happen.
There is an old G240D on ebay now that brought more money than what I am paying for the G350, I think I am getting a great deal even if I have to put a new engine in it. I am hoping to get a couple years out of the current engine but if I have to swap the 3 liter in right away that will be ok too.

Once the vehicle is warmed up, I don't think you need to worry about warming the fuel lines-- they get pretty warm all by themselves
so use a tank heater to keep the wvo flowing freely, then maybe a final 12v heater before it hits the IP, and you should be good to go.
post up your results, it'll be interesting

Toyota did - it's called the 1HZ. Same block as 1HDT but different head, injector pump, pistons, etc.
The more important question should be "why did Toyota not make a 1hz+t"? And the answer - they made the 1HDT instead.
Toyota did make a 1HZ-T, there's an entire thread dedicated to confirming its existence in this forum.
The post you responded to is from 2008 btw.
A different injection system, head, pistons etc makes it not a non turbo 1HD. A non turbo 1HD would have better fuel economy than a 1HZ.
Do the 1hz head and the 1hdt head use the same exhaust and intake manifolds? Another thread here suggests that the 1hdt head will take the camshaft and all the parts from the 1hz head? The 1hdt head will need different injectors and fuel pump mods is that correct?
Also wondering about the glow plug systems, I am lloking to build a 1hz hybrid.
