GKTech Nissan S13 SR20DET T28 turbo clocking adapter plates

The GKTech T28 Turbo Clocking Adapter Plates are designed to make turbo clocking simple and secure when installing or adjusting T28-style turbochargers on your S13 SR20DET. These plates allow you to rotate (or “clock”) the compressor and exhaust housings independently for optimal positioning of intercooler piping, oil, and water lines—especially useful when fitting larger turbos, relocating lines, or improving clearance in tight engine bays.

Each adapter is CNC-machined from billet aluminum for precision fitment and includes extended mounting hardware for a clean, bolt-on solution. No cutting, welding, or guesswork required—just fast, efficient turbo positioning exactly where you need it.
