Sure looks like a Coaster 15BFT to me. Mine had the larger flywheel and half of the two piece bellhousing setup. I took that off and fit a smaller flywheel and the old 3B bellhousing and associated components. The 8 bolt smaller flywheels are hard to find, so if you have the right one you're lucky! NB, my 15BFT came with a front hump sump, and you'll likely need a rear hump sump and associated internal oil pickup for diff clearance. A 3B sump can be modded to fit (just weld the front holes, grind clearance, drill new holes) - NB: not all 3B sumps are the same so you need the matched pickup to avoid bottoming it out on the sump. A megacruiser sump is rear hump and potentially also larger capacity, but may be hard to source.
From what I've been told, that turbo shares a core with the 1KZ CT12B but the compressor housing and wastegate are different. YMMV. If it is tired, a replacement core from the 1KZ v version may be suitable, or there are large bore front housings from some aftermarket suppliers in Asia.
You need the starter that went with that bellhousing, AFAIA nothing else will fit. Lots of toyota starters are 50% the same, but the piece that mounts to the bellhousing is model specific. You can actually swap the motor part over etc but have to be attentive as some may rotate other directions etc. I am confident you need the starter, or at least the piece that mounts to the bellhousing, that went with the bellhousing you have. The clutch fork and slave etc will also likely be specific to that bellhousing and should have been sourced at the same time. Is it a BJ7X bellhousing, clutch fork, slave, and B spline H55F that you're using? I would imagine these are not common parts in Texas unless coming from Canada or down south?
Yeah, the feed pump is down there but the primer isn't, there's something in the way of the usual position of the primer on a toyota diesel, and I assume they also put it the primer up high on the intake manifold so that it can be reached from the top of the service hatch. What setup does yours have for the accelerator? Sometimes the wreckers remove the whole linkage so people jury-rig something down at the IP.

Red is the accelerator linkage, you can just see the bit at the top where you need to connect the throttle cable. Mine is missing some bits, and all of the idle up components.
Purple is the vacuum engine stop actuator from memory, just zoomed on old pic from my phone so sorry about poor angle etc. The 12V VSV from a 12HT is suitable for this from memory, so should be normally open (12V applies cuts of vacuum to that actuator, allowing the engine to start).
Also pictured is the 24V Coaster starter. I also have a BJ7X 3B starter and bellhousing setup somewhere in storage but it's a 24V starter. If you have a BJ7X bellhousing, you need to get on the EPC's and find a PN for the matching 12V BJ7X starter.
In a 40 series the 15B series power steering reservoir needs to be moved for clearance to the firewall. It's tight but fits, the coaster 15bft manifold is smaller than some of the others! Mine is RHD, so can't help you re: brake booster / master clearance. Check out Harvard's conversion, from memory he has a thread on mud and this blog. I think he needed to move the proportioning valve or something RHD:
I was planning to put a 1HDT in my 42, but for many reasons i will not go into i ended up with a 15B-F. The 15B-F is a 4.1 litre 4 cylinder diesel engine. Often found in the big Dyna trucks, and al…
