2004 2.3L Engine swap HELP?

Hi.

I'm here to ask about my 2004 Ford Ranger 2.3L 5-Speed

My current engine just called it quits on me and I'm looking to do a swap with a few friends. So, what could I throw inside of my truck? What years are compatible? I'd love something with more power because I'm tired of barely being able to pass a mini-van on the highway lol.

So is it possible to drop a V6 4.0L in it? Or would it blow the rear end or is incompatible with my current transmission? I'm completely ok with putting a new 2.3L in it again because I'm looking at getting this thing back on the road as soon as possible I'm just curious as to what is compatible with my truck and if it's possible to put something in it that has more power.

Any suggestions or advice is greatly appreciated. This is my first ranger. Thanks!!!

The old 4.0l OHV, popular swap, only had 160HP, your 2.3l Duratec had 144HP, so not a good swap

Ford switched Rangers(1983-2000) from the Lima family of engines 2.0/2.3/2.5, 4 cylinder 119HP, to the Duratec 4 cylinder in 2001, first the 2.3l(2001-2010) then the 2.5l(2011-up)
Lima and Duratec engines are not related in any way, so you don't get confused when looking at engine info posts.

Swapping to a different size engine always requires swapping engine wiring harness and computer, Ford added PATS(passive anti-theft) to the Ranger computers in 1998 so that adds another layer of complications.
And yes, 4cyl trans may not fit or last with more torque from a larger engine, same with axles.

IMO, your best bet is to find a low mile 2.3l duratec engine and put that in.
Put vehicle up for sale and buy another Ranger with a 4.0l SOHC engine 207HP

Great! Thanks a lot.

It has rear end body damage so it's not likely I'll get much for a re-sale so i'm going to drop another 2.3L into it and just keep it as my daily drive. Even though I'd love a 4.0L 4x4
