Hey Guys, How is everyone? I have an 89 Trooper with a 2.8. My goal is to get the best possible gas mileage and I am wondering if anyone has any suggestions. In my mind the options are to rebuild the 2.8 in a way that would optimize gas mileage or upgrade to the 3.4 and build it to optimize gas mileage. Diesel is also a remote possibility in my mind. Does anyone have any insight on how I can accomplish the best gas mileage with the options listed above or any options I have not thought about. I would like to try and get 25 mpg or better and also improve power... (I know I am asking for a lot). Is this possible? All suggestions are welcome.
