Full Atmospheric or Recircular

i've been wanting to put a BOV on my04 wrx for some time now, but have been reading mixed opinions on which is better. the car is completely stock, with my hks exhaust coming in next week sometime. the bov that i have now is a blitz dual drive that came off my 99 eclipse gs-t. i've gotten the bov flange off of a turboXs bov that seized up on my friend. just need the 411 on which to use.

Get a GFB and you can go either way.

Atmo makes more noise, recirc will help you stay spooled up. Go with whatever you like better.

will going full atmospheric cause any drivability factors?

Nothing really to worry about.. You will run a tad bit more rich between shifts.

I have been running my GFB at 50/50 for about a year with no problems whatsoever, I just switched it to 100% atmospheric and still no problems after about 30 min of driving. no bogging, no stumbling.

had a m8 who had a blitz d/v installed into his 97 uk impreza turbo and whenever he changed gears the rev's would drop and the engine would try to stall, idling the car would be on the verge of conking out.....but when he re-fit his oe d/v it ran fine....
