GSC P-D Nissan VR38DETT 33.15mm Head +1mm OS 91.95mm Long 6.6mm Stem Exhaust Valve - Set of 12

This set includes 12 GSC Power Division exhaust valves specifically made for the Nissan VR38DETT engine. Each valve features a 33.15mm head diameter, a +1mm oversize dimension, a total length of 91.95mm, and a 6.6mm stem diameter. These valves are a critical component for your engine's breathing system, responsible for letting exhaust gases out efficiently.

When you're rebuilding or upgrading the top end of a high-performance engine like the VR38DETT, the right valves make a significant difference. GSC Power Division is known for producing well-built engine components, and these exhaust valves are no exception. The +1mm oversize design allows for a larger valve seat contact area, which can help improve flow and sealing, especially if you're porting or modifying the cylinder heads. The 6.6mm stem diameter is a common size that works with many aftermarket valve guides and spring setups.

Installing these valves is typically part of a larger engine overhaul or performance build. It's important to ensure your valve guides are properly sized for the 6.6mm stems and that the valve seats are correctly machined to match the 33.15mm head diameter. If you're working on a VR38DETT, especially for boosted applications, ensuring your exhaust valves can handle the heat and pressure is key to reliability and performance. This set provides all 12 exhaust valves needed for a complete engine rebuild.
