These items are designed to replace the factory Intake and Exhaust side Valves. Select materials and design developed for improved flow efficiency on tuned engines. In addition to smoother flow into and out of the combustion chamber these items are developed to be lighter and stronger than the factory counterparts for enhanced durability on high revving high heat applications.

Brand: Tomei
Product: Oversized ValveSet - SR20DET
Part Num: 163401
SPECIFICATIONS:
Valve Diameter (mm):
- Intake: 35.15
- Exhaust: 31.15
Stem Diameter (mm):
- Intake: 5.97
- Exhaust: 6.94
Stem Length (mm):
- Intake: 101.4
- Exhaust: 102.4
PRODUCT NOTES:
- Sheet Cut is Required
FEATURES:
1mm OVERSIZED WAIST SHAPE:
- 1mm oversized valves were designed for increased flow efficiency on both the intake and exhaust side. The stem has a thinner design for maximizing air flow rate within the port with the reduced air flow resistance. This design with the materials used also allowed for a lighter product as well.
PRECISION DESIGN:
- To maximize the potential of the valves purpose each factor was addressed during the design process from the surface of the valve head (umbrella section) & the Valve Seat, from Stem to Cotter are all optimized with precision for optimum operating & sealing capabilities when needed most during extreme conditions.
SURFACE TREATMENT (INTAKE SIDE ONLY):
- Improved Wear Rate
- Improved Fatigue Rate
- Improved heat resistance
- Improved corrosion resistance
HIGH HEAT RESISTANCE:
IN: SUH35 MATERIAL:
- The SUH35 material which is known for it's high heat resistance properties are usually used for the exhaust side. We chose to use it for the Intake side to suit the the demands of today's users for big power applications and for increased life.
EX: INCONEL 751 MATERIAL:
- Since the exhaust side can experience extreme exhaust gas temperatures of 1, 000 degrees C (1, 832 degrees F) during high power use the Inconel 751 material was no doubt the best option to choose to suit serious needs when every detail counts.
COMPATIBILITY NOTES:
- Only for Silvia with SR20DET engines.
