GSC Standard Exhaust Valve – Toyota 2JZ-GE / GTE (29mm) – GSC2061-01
High-Flow Stainless Exhaust Valve for Toyota 2JZ Engines
The GSC Power-Division Standard Exhaust Valve is engineered for Toyota 2JZ-GE and 2JZ-GTE applications, offering a precision-machined 29mm head for optimized flow and durability. Built from modified 23-8N stainless steel, this valve is designed to handle high heat and extreme conditions without compromising longevity.
Advanced Design for Maximum Performance
Developed using advanced 3D modeling and simulation tools, GSC’s valve head geometry delivers superior airflow and reduced distortion under pressure. Each prototype is flow-tested in real-world engine platforms to ensure top-tier performance across the board.
Valve Features
