You're not going to like this, but it's the answer that I have to provide.

From your post it seems you're pretty new to engine swaps. A very obvious issue is the I6 configuration. You're going to have to start measuring and you're going to find you'll need to cut up the firewall. There s no easy way to swap this engine, if fact, this would be one of those "expert level" swaps.

If you're looking for anything remotely "easy" or even "easier", a 4.0 swap would be a good start, or adding a turbo to your 2.3L for a little bit harder than that.

I'm quite certain no one has done one, due to said master level engine swap know-how.

There is a LOT that needs to happen when fitting a different engine into a vehicle that wasn't originally made for it. I would start browsing through some of the engine swap threads on this site and others. Read every thing you can about the difficulties and solutions, and even abandonment's of the projects.

If you ain't first you're last
Yeah totally agree^

You'd need an engine obviously, an R154 transmission at least (v16x is better). The slave cylinder and clutch kit for your engine/transmission combo, a custom hose for the hydraulic fluid to attach your master to the Toyota slave cylinder. You'd need all the accesories from a 2j and a custom power steering hose to attach the pump to the rack. You'd need to figure out how your radiator would fit and also get an intercooler and figure that part out too. You'd need to fab custom motor mounts, trAns mount and crossmember. You'd also need a custom driveshaft, and would probably want to swap an 8.8 from an explorer since that 7.5" diff ain't gonna put up to the 2j. Couldn't put up to my 4.0l haha. You're gonna need to definitely cut out and re do the hole for the stick shift. A custom shifter also since it'll be in a truck. An ecu and wiring harness, then for the fun part, figuring out how to make the 2jz sensors communicate with your ignition switch, dash gauges, fuses, relays, etc. you'd need to probably hook the fuel pump and starter to their own switches for ease. You'll also need at least a walboro 255lph fuel pump. A custom down pipe and exhaust system too, and custom intercooler piping. You'll also probably wanna run dual e fans since the fan clutch is most likely not gonna fit with the already limited room you're gonna have.

I could go on for forever

I recently swapped a 1jz into my mk3 supra (which had a NA 7mge in it to begin with) and even in that car it was a challenging swap. A car which has a straight six to begin with, and came stock with a 1jz in Japan. Wiring was quite fun... Not! And routing the intercooler piping even tho it was meant for that car and motor was also a pain. Luckily I didn't have to make custom motor mounts or a driveline all that bolted right in.

Point being unless you have a boatload of cash, and all the time in the world, I wouldn't attempt it.

Get a 5.0 from an explorer and hook a t5 transmission to it. Done.

Also just realized you have an auto.. Yank that thing out ASAP, and get a clutch pedal assembly and all that jazz from a junkyard

If you have the time and money do it. I'd do it from a Lexus is300 you can find those at junkyards easy and boost it done. It's easier to do a 5.0 swap. More hp and way cooler having a v8. Or just boost yours.

With the right amount of time, money, and labor you can swap anything you want into your ranger.

Also 2JZ engines are quite expensive so you also have to front the cash for one.
