4g64 is the engine name and they can be found in mighty max\d50 pickups aswell as a 16V version with coil packs instead of a dizzy in the montero sport plus most of the car line uses the 4g64 and 4g63 motors aswell but they are narrow block you'd want a wide block for the montero or pickup they are a little more work for a montero since they are front sump but on toastys swap he just spaced it the engine up to clear the front diff. It was also used in the pajero in japan with a rear sump config so chances are you could order a pan and pickup but they are a bit pricey. easier to just space it up or rework the pan your self.
