question on evo parts

[DOHCSIDE BOOST]

ok say i get the evo manifold, O2 housing, and the (evo) big 16g. all this would bolt onto my 98 gs-t right, well my question is do i still need the hacker/tweeker kit from rre? or could i pull this off just doing the new oil/water lines?

still need the kit, turbine outlet still exits up top
