My 92 Turbo Sedan has a huge TurboXS adjustable blow-off valve (aka compressor bypass valve) with 1- 3/8" inlet and outlet. The stock cheap plastic cpv that came OEM from Subaru used 3/4" inlet and outlet. Initially I adapted my BOV down to 3/4", which added an unreasonable amount of length and was just dumb. The inlet nipple for the cpv on the rubber elbow that goes from the plastic resonator oil separater to the turbo is notoriously likely to crack and tear. I bought a short piece of 1-3/8" radiator hose, cut out the opening in the elbow and glued the two together with black Shoe Goo (available at shoe repair stores). After the initial round set up, I reinforced the joint by adding more Shoe Goo and layers of fiberglass cloth. I finished my handiwork with satin black paint, as the Shoe Goo was more shiny that the OEM elbow. Now my fancy BOV ducts perfectly into the stock turbo intake. When my original elbow nipple puked I made an on-the-road repair with Marine Goop, which is exactly the same as Shoe Goo, except it has UV stabalizers. I know for a fact that it holds well in this application. When I am in an aesthetically enhanced mood, I might wrap this elbow and my spliced on hose with bicycle handlebar tape just so it won't look quite as "Road Warrior".
