A few other people actually pull the entire tube out, and weld the hole shut. I'm assuming that it is there for perhaps the extra stress/flow that the STi has compared to the RS, so I wouldn't pick 'yes' or 'no' because my application with my EJ257 is higher compression non-turbo....

But before I siliconed it shut, I had oil spewing everywhere out of that breather. The whole block was covered in oil and the oil was burning off under the hood, creating a large cloud of smoke. Other cars beside me looked quite nervous.

No there's no need for a turbo crossmember unless you want to eventually use turbo exhaust components. I reused my old oil pan and headers. Using a turbo crossmember is mainly for clearing an uppipe.
