I have slowly been building a list of improvments I want to make to my KT4 when I start to rebuild it . Engine type and size is one of those considerations . I hear alot about the new turbo diesels but then for years the snow cat companys ran their snowcats with gas engines . Is there an advantage of Diesel or Gas over the other ???? I have been looking at the small pickup diesels that are turbo powered and wondering if they might work . There should be a ton of them in the auto dismantlers to choose from ????? I figure I'll need about 80-100 horsepower . What are the pros and cons ???
