[Irace86.2.0]

I did some searching. I came across opinions on setups, on different manufacture's offerings, etc, but I didn't find what I needed or didn't search enough.

I'll be running a Harrop SC with their CARB tune when it is released. I've been told to buy the WRX FA20DIT PCV valve, and I plan on running a PCV catch can, but not a dual catch can. I just doubt it is necessary, as I am not a track junky. My limitations are that I can't run an open system, not with putting filters on valves and venting to air, and not with putting filters on catch cans and venting to air. CARB allows for catch can/s to be installed, but the can/s can't modify the emission equipment more than routing a few new hoses, and the can/s need to be a closed system.

I figure I can replace the PCV valve as described above and get a universal catch can to route the hoses and be done with it, but some have said that the WRX PCV valve isn't needed when using a catch can, so I was hoping to get that clarified, and I also wanted opinions on catch can setups for NA vs forced induction. The only difference seems to be people recommending two vs one catch can, but I have seen multiple posts from people saying their catch can for their breather hose gets almost no output, and those are from people putting down some track time, so I am curious if a dual setup is worth the money, and I am curious if the install is different than putting a catch can between the PCV valve and the line running to the intake like on NA applications.
