well yeah, they are 11 mm top feed injectors. Snag a 11 mm top feed rail and its plug and play for a Rb20/26 . For the 25, you still need the adapter for the injector ports (from the site noted), to make them fit into your manifold. Once again the rail will fit any injector as long as its the same diameter top (10mm to 10mm, 11 to 11)
