My '89 Cruiser gets both horrible gas efficiency and performance. I have been hearing about people putting diesels in their Cruisers. I was wondering if there is a production FJ60 Diesel Cruiser or if they are fabricating their Cruisers to fit the engines. If they are fabricating to make the engines fit what else is entailed. New tranny? Driveshafts? Axles? Ect. I would just like to know more about what is involved in putting in a diesel engine and what is the engine of choice. Thanks in advance!
