keep the pcv valve in the valve cover, cap it. Take the nipple from the intake manifold and cap that as well. Deleted.

Or do what he said, but you can utilize the PVC port as an extra crankcase relief line so you don't have to tap one yourself.

Here is a nice thread regarding some EVO guys running high boost: Fucking Crancase Pressure & Stupid PCV Valves

That should give you some ideas on what to do.

As for the PCV valve, I believe the RR style is different than all other SRs. It has a floating valve in a grommet type fitting. I've never taken mine out so I'm not sure if there is a thread pattern in there. The idea would be to cap the entrance to the intake manifold and install an open fitting in the valve cover in place of the PCV valve. You would ideally vent this fitting, and any other vacuum hoses coming from your valve cover, to a catch can/crankcase breather of some type. This will allow for more crankcase ventilation under boost.

Also, you will get flamed by many people for deleting the PCV valve, but in my experience it's not needed and is only there to draw in crankcase gases to be burned in the combustion chamber at low throttle and idle. The benefit from deleted the PCV valve will be a rock solid idle, and less oily gases entering your engine, while creating an extra port for your crankcase to vent under boost.

The RR pcv valve fits into a grommet, it's not a threaded type pcv valve.

That exactly what I was thinking, just throw a couple of vacuum caps on and be done with it. Does it matter where you put other breather on the intake before the turbo?

I recommend you learn how the system works and why, and then you can make up your own mind about what to do.

Here's a write-up someone did that seems to explain it: http://www.sr20-forum.com/information-library/44727-crank-case-ventilation-fully-explained-turbocharged-edition.html
