You may want to check out the diesel forum. Tons of info on diesels, also check out the diesel link in the tech links. I have a 1HZ w/ a turbo, but it is sitting in a shop waiting to be installed. I drove a non turbo 70 series w/ a 1HZ in Costa Rica and it was very fun. Good solid power with more to give. Had a pretty steep hill to climb up to the hotel, no problem. It also can get very good milage. 20-25+. But they are not cheap. Do lots of research.
