Seca Turbo System Thought

unforutnately, i do not have an intimate working knowledge with the setup on the factory turbo xj's. I have had some experience with turbo cars though (my daily is a wrx) so I just thought i'd throw in my .02 on the automotive bypass/bov.

subaru's use an open under vaccum/ closed under boost via a reference vac source on the wrx/sti/05+turbo legacy. it is actually plumbed back into the intake so it's considered a recirc valve. i believe that 1st gen dsm's use a similar design (flanges likely vary from application to application)
