Racing Valve Set, R32-R34

Tomei high-flow intake and exhaust valves for the RB26DETT is a must for any performance, race or street build. Designed with race spec high heat-resistant alloy, these valves can take the punishment faced by boosted motors. Tomei waisted stem necks down the valve in order to gain that extra air normally resistant against the valve on stock or other aftermarket designs. Made with the serious Skyline owner in mind, we are proud to offer these Tomei valves in our performance line-up.

• 65mm Intake Head Diameter
• 97mm Intake Stem Diameter
• 30mm Intake Length
• 15mm Exhaust Head Diameter
• 94mm Exhaust Stem Diameter
• 20mm Exhaust Length

The waisted stem allows a greater volume of air/gases to enter and exit the combustion chamber as the valve extends.

Each valve is designed and precision machined specifically for the intended engine/application. The head, face, stem and lock groove designs have also been optimized to enhance sealing performance, efficiency and durability.

The intake valves are made using SUH35 HEAT RESISTANT STEEL which is more commonly used to make exhaust valves. These are then coated with a special formula that further improves the valves' resistance to heat, wear and corrosion. In order to withstand temperatures of up to around 1000℃, the exhaust valves are made using a nickel based heat resistant alloy, INCONEL 751.
