Thank you, Roma. I thought this would have much more interest since these are very nice little engines.
Here is a write-up from Stranden's Garage where he installed a 15BF into a BJ42 for reference:
15B-F engine in a Land Cruiser BJ42 - https://strandensgarage.wordpress.com/2011/12/18/15b-f-engine-in-a-land-cruiser-bj42/
These engines will come from Hong Kong from the Toyota Coaster Bus application. The five (5) engines we have brought in already have around 170,000 Kilometers on them (slightly over 100K miles). On the Coaster models, the deep part of the sump is forward from the center of the engine, therefore you will need to find the sump from a Dyna (like the one shown on the link above) and modify one of the "wings" to clear the front Land Cruiser driveshaft or buy the one from the Mega-Cruiser which will be a direct fit with no modification. When replacing the oil sump (whether from a Dyna or Mega-Cruiser), the oil pickup tube will also need to be replaced to match the respective sump. Additionally, on the Coaster iteration, the dipstick is mounted on one of the sump "wings", so a Mega-Cruiser dipstick and dipstick guide will also need to be replaced. The beauty about these engines is that Toyota already drilled the block to accept the other dipstick mounting location and blocked the hole with a freeze-plug like plug. When replacing the sump, you simply knock the plug out and install the new dipstick guide. Super simple.
These 3 parts are the "must" replace parts when buying one of these engines and planning to drop them into a Land Cruiser (oil sump, oil pickup tube, and dipstick). They are around $500 for all the parts (maybe slightly north of $500). Other parts would be regular maintenance items like water pump, belts, thermostat and such. Also, these engines have a glow-screen (no glow plugs).
Hope this helps,

Relatively "bolt in" setup, but there are lots of things that add up, especially with the 24V coaster version 15BFT, will likely add up to significantly more than USD500:
- as noted above: late B series rear hump sump + oil pickup (3B ones can be modified but having done this I wouldn't recommend it), B series block mounted dipstick and tube
- all 24v parts swapped with 12V versions: sensors (most original 3B ones work and make it relatively simple swap), alternator (there's a 1HZ twin belt version which fits some Coaster 15BFT), etc
- glow screen likely not required unless sub zero temps are common, 12V version from 1HD variant *may* fit
- new alternator/charge wiring to suit internal reg alternator, and matched belts as alternator likely to shift position if using the above substitute
- large 2 piece bellhousing style 15BFT flywheel won't fit in a landcruiser bellhousing, need to buy the smaller version new from Toyota or find a later 3B / 3Bii with an 8 bolt flywheel, LC 3B flywheel is smaller and 6 bolt so won't work
- 40series cast iron bellhousing will need grinding/clearance to fit larger flywheel, aluminium/70series version may not
- new clutch disc and pressure plate to suit chosen flywheel, chosen pressure plate might required different throw out bearing and mods per StrandenGarage (mine didn't)
- assorted plumbing/hoses/intake/exhaust components
- p/s hoses and reservoir relocation to clear 40series firewall
- may require new rad or top thermostat cover depending on whether ideal port position for application is on right or left
- factory 15BFT A/C bracket has to be removed to fit 40 series engine mount brackets in forward position
- rad/fan cowl may need mods/repositioning
I'm sure there's a few more things I've missed. My 15BFT swap has been sitting unloved for quite a while so it sin't fresh in my mind
