I bought a 94 FZJ80. I was able to find a new short block and obviously have to get the top rebuilt. I also found a remanucater company that will use OEM parts. I get different opinions. What seems obvious to me is to go with the new. Other's say the remanufactured will last as long be less expensive and a better warranty. I should include that the motor starts right up. There is an engine knock and that is the reason for the engine replacement. Any ideas?
