All I have to say is the engine really looks great and is very clean. That is pretty much putting in a brand new engine into your Trooper. The results should be excellent when you do first drive it. I'd have to say you would be pulling down at least 30 MPG also since everything is new. And your power is going to be good too, after using a K&N air filter, you'll probably be around 85-90 HP. Isuzu diesel engines are awesome! Keep up the great work and good luck with the remaining project.
