Hello, My appologies if this is the wrong section for this, but here goes... I've got a 78 fj40 with a 81-83 2F engine in it. Runs good, but I think it will need to get rebuilt fairly soon. I am considering just getting a diesel and 5 spd tranny instead of rebuilding the 2F. It's daily driven, on (70%) & off (30%) road, and it gets very cold here. I've been reading up on the diesel swap subject and have gone from a cummins 4BT or GM 6.2L to a toyota 13bt or 1HZ with H55 trans. So, between the 2 mentioned toyota diesels, which would be the best for a swap? Has anyone here done a similar swap? I want to know if this seems foolish or if it is possible. Some of my concerns are parts availability and fuel economy. I'm not that concerned with having lots of HP, just a reliable engine that won't be parked for weeks waiting for parts.... Sorry to ramble, and thanks for reading.
