I don't have a BOV on my RB26DET..if you're looking at the pink part near the turbo then no,that's not a BOV. It would've been placed on the piping between the intake manifold and the intercooler. If you want the BOV onto the single turbo setup,you can try to look for it's SCX and TEX in the DETT meshes and swap it or something. 🙂
