Do you reckon you would be able to put an aftermarket ( or even stock maybe) BOV onto the capped hole at the end of the stock elbow ( check pic) ? I think it has something to do with the old warmup system. I've heard a lot of people say that a BOV nearest to the throttlebody is best so I'm figuring that this is already in a good place, what sort of problems might you expect if any?

 

i have a stock bov plumed in there now that i have a single turbo set up. work well

 

I had some friends who did this as well~~~ and yes it does works well~~~~
