I did all the work myself, so not much at all. Replaced the rings, water pump, gaskets, belts, bearings, top to bottom seals the only thing I didnt touch was the valves as they were still pretty good. Got a new clutch, cv boots and all fluids around. After I was done it had cost me about $1100.oo on all that the engine gearbox and loom/ecu was picked up off medicine man for $550. Had to change the fuel tank and add lines so got them cheap off a wrecking sx. If you were to take this to a shop and get it done I'm sure it would cost a bit in labour as well.
