Well, we can start off with the actual engine mounts, how will you have them made unless you know how to weld? (keep in mind at this point your truck is sitting with no engine, and the 2jz dangling by an engine hoist. Will you contract a fabricator to come over to your house? measure everything, then run back and forth between your place and his machine shop?), then what will you use to adapt the 2jz to your transmission? What will you use for a torque converter because the splines are very unlikely to match up. Custom torque converters, not that cheap.
BTW, good luck finding a good used 2jzgte for anywhere near a reasonably price. Enough time has passed that you can't just find a bunch of JDM ones in a warehouse, and everyone from Supra guys, Lexus guys, hell, even Mustangs, 350z's, 240's are putting those into their cars.
Next, it's very unlikely the factory turbo system to exhaust will just line up to the 4runner chassis, cross members, etcso I'll give you a break and just assume an eBay manifold puts the turbocharger in a reasonable enough place and you won't have to have one made, you still need a fabricator to work out all the wastegate recirculation to exhaust plumbing.
Next we have wiring, engine management, tuning. Do you know how to do these things? --And have the speedometer, gauges, warning lights, shifter all work. Do you know how to do all that? Without it being months of work?
Then comes all the trivial stuff, finding the right intercooler to fit behind the stock bumper, fabricating mounts, fabricating intercooler plumbing, the stock ecu will work, but might throw 10 different engine codes including emissions codes, so you'll either have to hunt every single one down or go with an aftermarket engine management system and tune.
Next we can move onto reliability, those one-off wastegate recirculation pipes might not like the bit of flex from those one-off engine mounts or the flex of the factory 4Runner transmission mount, the vast, vast majority of stand alone engine management setups need constant attention. That 20-25 year old engine harness that you found used from that guy on craigslist has now been hacked, cut, extended, etc, runs across hot spots in the engine bay, etc. This also assumes there is absolutely nothing wrong with that used engine, electronics, etc. Good luck getting your money back for them after you've had them for months trying to get it to work in a one-off setup.
Finally, some day, that sweet 2jzgte is going to make some good power, mild setups will make 450-600 crank horsepower. The 4Runner stock transmission probably won't hold that and will blow up. What now? Keep blowing up stock transmissions? Find someone to build a one-off built one? Figure out a way to adapt the Supra transmission to your transfer case? Repeat step one.
So we have...
Good used engine
Custom engine mounts
Engine harness
Intercooler
Custom plumbing
Turbocharger
Wastegate
Blowoff valve
Custom plumbing for all the above
Custom torque converter
Custom engine to transmission adapter
Stand Alone Engine management
Tuning
Electrical's unless you're really good with these.
Then any frankenstein car, you better be good at troubleshooting and working on stuff on your own. Most shops won't want to touch it.

Why is it so wrong?
How do you know it's so expensive? Did you try it, spend a crapload, and then just want to dog someone else because you learned the hard way?
bring up some factual information instead of opinions..
