Haha,well it was a little more than I wanted to spend. I bought the truck without a motor,well it was sitting in the bed. So I had planned on doing some kind of swap anyways. My plans started off with a 3.5 gas out of a 2001 Montero xls, I didnt want to mess with all the wiring. If you want to actually plug it in and go,my opinion would be the 4d56. It cost me $2500 for motor and transmission. My truck had an automatic already, an I wanted to keep it that way. I've had diesel for 15 years,the gas mileage pays for themselves.
