Supertech Nissan RB20DET (w/Solid Lifters) Inconel Exhaust Valve - +1mm Oversize - Single (D/S Only)

If you're rebuilding the top end of your Nissan RB20DET engine and it uses solid lifters, this Supertech Inconel exhaust valve is a solid choice for replacing worn or damaged valves. This particular valve is oversized by 1mm, which can help restore compression and proper sealing in engines with worn valve seats or guides. The Inconel material is chosen for its exceptional heat resistance, making it ideal for the high temperatures found in the exhaust port of a performance engine like the RB20DET.

This valve is designed specifically for the driver's side (D/S) of the engine and is intended for use with solid lifters, meaning it requires manual adjustment for valve lash. Using Inconel helps prevent valve distortion and burning under extreme heat, which is common in turbocharged applications. The +1mm oversize means it's slightly larger in diameter than the stock valve, so it will require matching valve seats to be machined to accommodate the new size for a proper seal.
