I did Rocky 1 about 4 years ago. Cost about $6k all up. A lot I know...
Wasn't until I tallied it all up that I realised.
Costs were:
Brand New Daihatsu OEM head $1300
Injector pump and injectors $1300
Bottom end (below the head) proffesionally rebuilt by Southcott's in adelaide $2500 (included new bearings, pistons, liners, valves for the new head - they dont come with valves, machining, etc).
Plus other assorted junk (water pump, hoses, etc, etc).
Mind you, the engine was still running when I did the rebuild. Was just a bit tired thats all. Have done 100,000km's since and still going well.
To be completley honest I probably wouldn't do it again. Just get a second hand turbo motor with low km's and chuck that in. It's probably the same cost by the end of it.
Other thing is, cos the DL motor uses liners, you can have difficulty getting the new liners to fit properly. Like most cast Iron block diesels, the blocks warp slightly and unless you get proper heat conduction from the new liners to the block, they will crack. It's difficult to explain but it all makes sense.
Good luck
