I have a question I just wanted to know what nipple the vacuum hose is suppose to go to the big one or the small one. I cant remember. I had it off for awile and right now I have it hooked to the small one on the bottom. I for some reason believe thats where it was suppose to go. Just want some confirmation on that. This is the purple Greddy BOV thats all I know. I bought it used from a guy on here awhile back it came with that pipe made for the FCs.
Thanks
Jeremy

interesting in deed...
Does this mean i shoudl hook up the lower small fitting onto the same fitting as the internal wastegate?

 

You can, but you don't have to. Only do that if you get surge no matter how you adjust it.
