Around here,the straight engine swap, with a good donor(used) engine of the same type is about 3000 or 4000 dollars. Plus about 1800 if you decide to do a rebuild on the engine before you drop it in. There are a bunch of these lumps around, they found their way into all kinds of vehicles. A new one a bit more yet. By the way, I regularly get 18-21mpg here in semi-rural Fla., all two lane stuff, no highway. Oh yeah... when you buy a "donor" or a rebuilt engine they do not include the accessories,alternator,compressor ect. and often not the heads...no big deal just know what you are buying. This is relatively minor surgery, and no reason not to buy an otherwise healthy vehicle.
