Its around $3,000 for an F6 short motor, plus R&R engine, strip, and change over all parts, gaskets etc. I would say around $6-7,000 all up. that's providing there is nothing else wrong with your engine. Your cylinder head would need doing up, and other possible repairs(turbo maybe) I have just done my ute, engine blew, and I fitted a new F6 long motor. I needed quite a few parts, that's why I went with the long. Had turbo rebuilt, new radiator, all new belts, and hoses. Dont ask on the total price
