Welcome to the forum. First off, start reading and looking for swaps of a similar type. Second, might check the laws in you state to be sure the swap can legally be done. Some states don't allow swaps where the engine is older than the vehicle. This vehicle is like brand new. Curious as to why a swap? You'll probably run into some computer issues. Everything on your vehicle is controlled by a computer and nothing on that engine will be. If the engine in the skid steer has its ID plate on the side of the front gear housing, you can look up your engine on Cummins Quick Serve on line. It will show you every part of the engine as originally manufactured. If you decide on a swap,then you need to do some measuring to make sure a fit is possible. Also, have to figure out what transmission you'll use, whether your axles are strong enough, and all kinds of wiring issues. These engines are not a feather. Typical 4bt will weigh around 750 lbs. They like to run in the 1700-2000 RPM range so you need to be sure your gear trains fits that. Also need to think about a budget. Figure the engine will need some amount of rebuild. Things like gaskets, seal, and bearings are normal basics. May want some improvements to the power level. Possibly a better turbo, depending on what the engine has now. Injectors need to be checked to be sure they are within tolerance. May replace basics like water and oil pump just to be on the safe side. One main thing is to find out which injection pump your engine has. There are 6 or 7 different ones and some of those aren't very useful for road vehicles. Replacing an injection pump can get quite expensive. If you can find the engine serial # on that ID plate I can look up the engine on my quick serve to see what you have.

 

Wow I didn’t think about all of that, thank you for the advice I’ll look around and see if I can find someone on the forums that has done a similar swap. I’m part of a 4Runner group on FB and no one has done one in a new model and was just curious about doing it to mine.

 

If you'll find the serial number for the engine I'll look at its specs to see if it has potential for your project. On a vehicle that new, one would sort of lean toward the new Cummins R2.8. Main issue there is you're looking at quite a bit of cash outlay. Engine in a crate will cost you $8000 and then you have to adapt it. Main plus for that one is it's 50 state smog legal.
