Is there any play in the shaft? What is required to make it work on my TII(s5)? Custom oil lines? Exhaust manifold?

you need a manifold with a TO4B flange. as far as the oil lines, you might need to buy new ones for the new turbo since the distance would be different with the new manifold. other than that, fuel upgrades, and maybe a front mount would help. normal stuff like that.....
