What about the breather hose?
I am finishing my custom piping, and I wanted to know whether I should do a fitting to connect the breather hose coming from the valve cover to the pipe that is going to the turbo inlet.......I have seen some kits which do that, while others just use a breather filter.....But also I´ve heard that breather filters are bad because pressure builds up in the oilpan, and rings dont sit well........
What would you do?

I would do like Haberdasher did with his setup. Crankcase ventilation is very important. I would definatly put a fitting on the intake pipe. Look at his post that's titled "Pictures, pictures, pictures...." That should do it for you.

Ventilation will not be the same if you are releasing gases through a breather filter, than it would be if you were sucking through the intake pipe.......
Furthermore, there will be MUCH more venting if a T3 housing is sucking air :P

So, what happens when you hit boost? Does the crankcase get boosted? I don't even have a filter on mine. Just a hose.

Good god man. That would require 30 feet of extra hose under my already not-so-clean hood. I think I'll stick to atmospheric ventilation for now. :P

Re:What about the breather hose?
When you're under boost the crankcase does not see boost due to the PCV valve. It acts as a one-way valve so if there were a backfire through the intake manifold, it would blow flames back into the crankcase. The problem with that is while you ARE under boost the crankcase is not being vented due to the valve staying closed. Make sense?
