I need help with what exact tools is needed to replace the factory evo 8 o2 housing to replace it with a external dump. I need info on what parts is needed to take off for an easier work. Thanks in advance.

 

it's easiest if you take the manifold and turbo off. You almost have to because the bolts are going to be so damn tight. So with that you need to take the radiator out, disconect the down pipe and remove the IC piping. Good luck! I paid $175 to have mine put on.
