Fitted mine on the weekend, I won't lie it's not easy lol Start by removing your radiator, gives you loads more room and doesn't take long. Then remove the efi pipe off the turbo - you need long nose pliers for the clip and can access that from underneath the car. While your under there undo the 2 bolts on the oil feed pipe and take off the oil return hose. The hardest bolt on the manifold is the bottom left nut, we removed the bracket on the power steering pump so we could access it. And as above like the others have said, just leave the turbo and decat/cat together and lift it out as one unit. Just undo the 3 bolt flange on the exhaust. I replaced my gasket from manifold to block with a genuine Toyota one. Hope this helps, good luck
