I'd never dd one. They arent fuel efficient. Save it for off roading. To make it reliable it will need a total overhaul which wont be cheap but then youd have a super reliable rig. For a more modern engine put a 1hz or 1hdt in it and you will be able to get spares. Still a cheaper and better option than buying a fancy new spandangled 4x4 full of electronics to fail.
