If you're rebuilding the top end of your Nissan RB26DETT engine, especially for performance applications, these GSC Power Division exhaust valves are a solid choice. They are designed to handle the demands of a high-output engine, ensuring reliable operation when you need it most. These valves are a direct replacement for your stock exhaust valves, but with an upgraded size to improve flow.

This set includes 12 exhaust valves, each measuring 101.74mm in length and featuring a +1mm oversized head diameter of 31.15mm.

When installing these, remember they are a direct fit for the RB26DETT engine. Ensure your valve guides are reamed to accommodate the +1mm oversized valve stems for proper fitment and function. This set is a great option for anyone looking to get the most out of their RB26DETT build.
