there's no nipple on the stock turbo. 1 hose to WGA and the other to the pressure source of your choice.
Yeah it's a terrible idea, which is why I ran them on both of my turbo Mazdas. **** no its not a bad idea. Don't believe everything that some people type on here! My turbo, wga, bpv, engine are 100% original with over 105,400 miles on them. I have no intention of opening up this engine and my other engine had 216,000 miles with the same parameters.
