Four cylinder, 6 cylinder, 8 cylinder, air cooled or water cooled, opposed or V, we've built them all. The Pacific Power Motorsport team has rebuilt literally hundreds of engines. Our most recent project is a 4.0L air cooled engine which ran a recent 25 hour enduro race. We were leading our class when we had an unfortunate incident, and though aerodynamically disadvantaged, we finished the race 3rd in class. A post race engine tear down showed minimal wear!
