when I done it changed sump,oil pump/pick up,bottom crank pulley,engine mounts,had to buy a bailey turbo damper(due to head) also have to rewire the temp sender wire(make it longer as it on the other side)and also changed the turbo oil feed pipe iirc
ps: you can use the 4x4 oil pump and p/up but you have to grind abit of the inside of the sump to clear the pump thou!
