The 1HD FTE will be an electronic engine where as your older 80 won't be so wiring of ECU's and harness's will test you. You have to get the correct ECU for auto or manual as well.
My suggestion is to look in 4x4 trader as some toyota dealers are selling brand new engines for around the 7 grand mark. If you decide to put a 1HDT in, which will bolt straight up and you don't need to source flywheels etc, this is my recommendation. You will have to get a fuel pump, turbo and some minor parts but would be worth the investment.
If you purchase one of these I suggest you do a main and big end bearing replacement prior to fitting for a bit of insurance so you know you won't get one with the bodgy bearings.

would also be much easier to source engine and trans along with wiring and black boxes all together. There are often big differences between engines conn to auto's and manuals especially regarding ancillaries.
Could end being much cheaper to buy complete donor vehicle to ensure all parts necessary are obtained. eg does donor vehicle have fly by wire or cable? etc etc.
Could also be much cheaper and easier to trade 80 in or get engine (as has been suggested) out of same vehicle series.

Thank you guys. Looks a bit more complicated ( = expensive) than I had first thought. Gotta love this forum and all its helpful advice.

I would suggest the 1HD-T, which is a mechanical injection diesel, in fact it is nothing more than a direct-injected version of the 1HZ you are pulling out. This engine will bolt straight in, but I would recommend an up-rated Daikin clutch kit to handle to extra torque of this engine. Some minor exhaust work to match your system and a couple of different intake ducts to the air cleaner box and away you go. It would be judicious to have the bottom-end bearings inspected too. Every thing else is a direct match up.This engine will pull the queen Mary out of dry dock, is simple to work on and returns excellent fuel economy along with the huge torque it develops from just 1600 rpm. Some people will can it because of a poor history of main bearing failure, but this is usually traced to poor driver habits along will the engines ability to lug from very low rpm's.

Hey
If you have sourced the hdfte, then you might be able to still use it....it has an electronic pump, so the options there is to use it with a wiring harness and computer out of a 100. There might also be diffeences in sumps as all hdfte were independant front ended...
Your flywheel will bolt to the hdfte or hdft or hdt, and the easiest motor to fit would be the hdft, as you dont need any glow system for it if you dont want to change things.
A few people have done the hdft to their 1hz 80's in lcool circles...and one i know of in a 105.
Same block, same starter, alt, engine mounts...no engineers on the 80 motor in the 80, as they came factory with one....
You may need to fit a pump to the diesel line, as the t/d hdt(ft) line is larger and they dont like restrictions...
Have fun....i would start looking at the damaged vehicles auctions if you want a complete conversion, but for the extra $$, a brand new long motor would be all you need.
