Welcome to the forum

2.3l engine?
There are quite a few
Ranger use 2 different ones, well 3 counting the 2.3l Diesel
2.3l SOHC Lima engine
2.3l DOHC Duratec

Ford used a turbo version of the 2.3l Lima in some cars in the 1980s
And then 2.3l DOHC got turbo'ed and Ford called it 2.3l Ecoboost and its used in the new 2019/20 Rangers

The turbo'ed Lima engines were pretty much the same as the NA Lima engine, just forged pistons and a stronger crank
2.3l Lima engine was first used in 1974 Pinto, so not very recent technology
But they can still be turbo'ed, and reports are they can take 7psi boost as is, if you want more then you need to get the turbo engine internals

None, if you don't use more than 5psi boost, if you want to go higher then forged pistons and forged crank
The problem with boost is the gasoline octane, regular gas will pre-detonate which damages stock pistons, so you should run 93 octane and then you could maybe do 7psi boost as is
So if you decide to boost any engine, then plan on spending more on gasoline for that engine, factory turbos use Knock Sensors, to change spark timing or limit boost so they can run regular gas(87 octane), when you add a turbo you don't have that option

The forged pistons can handle a bit more pre-detonation so boost can go higher, and the forged crank can handle the higher horse power

There is no "safe" boost number, engines fail with just regular driving, anytime you increase the horse power you place more stress on "the weakest link" in the power train, and you can try to guess where that weakest link is, lol, but it may popup somewhere else

Anything is possible

For tunes and add-ons try Mustang forums, Mustangs used the 2.3l Lima engine from 1974 to 1993
And those guys loved to play around with their engines

And have a read here: https://www.route66hotrodhigh.com/2300.html

Bro I was being a wise guy. Its a honda motor. You'll need a whole machine shop to fab one into that engine bay. Doesn't mean its impossible before.... I saw a video once of a 92 civic hatchback with a 6.0 powerstroke diesel wedged into the engine bay (no hood) and converted to RWD. Depends on how much you wanna empty your wallet.
