Product Overview
Supertech Toyota Tacoma Exhaust Valves – 2RZ-FE / 3RZ-FE +1mm Inconel Set of 8
Upgrade your engine’s valvetrain with the Supertech Toyota Tacoma Exhaust Valves TEVI-1047-8, a high-performance set of eight Inconel racing exhaust valves designed for Toyota 2RZ-FE and 3RZ-FE 16-valve engines.
Manufactured for demanding performance applications, these Supertech valves feature a 31.5 mm oversize valve head, providing a 1 mm increase over the standard 30.5 mm exhaust valve diameter.
The nickel-based Inconel alloy construction offers excellent resistance to high exhaust temperatures and thermal fatigue.
Whether rebuilding a Toyota 2RZ-FE 2.4L engine or preparing a modified 3RZ-FE 2.7L engine for performance use, the TEVI-1047-8 valve set provides precision-engineered components for a professionally prepared cylinder head.
Why Choose Supertech Toyota Tacoma Exhaust Valves?
Exhaust valves operate in some of the hottest areas of an internal combustion engine.
During high-load operation, especially in modified or forced-induction applications, valves are exposed to elevated exhaust gas temperatures and repeated thermal cycles.
Supertech manufactures performance valves using carefully selected materials and controlled production processes.
The TEVI-1047 range uses Inconel material to provide excellent high-temperature strength and resistance to thermal fatigue.
Inconel Construction for High-Temperature Performance
Inconel is a nickel-based superalloy recognised for retaining strength under demanding thermal conditions.
This makes it suitable for exhaust valve applications where heat resistance and durability are critical.
Supertech’s Inconel racing valves are particularly relevant to properly engineered high-performance and forced-induction engine builds.
31.5 mm Oversize Exhaust Valve Head
The TEVI-1047 exhaust valve has a 31.5 mm head diameter.
This represents a 1 mm increase over the standard 30.5 mm exhaust valve specified for the Toyota 2RZ-FE and 3RZ-FE cylinder heads.
When combined with suitable cylinder-head machining and an appropriately designed engine build, oversize valves can contribute to improved exhaust flow capability.
Actual performance depends on valve-seat preparation, port design, camshaft selection and the overall engine configuration.
Precision-Manufactured Racing Valves
Supertech uses controlled forging and machining processes to manufacture its performance valves.
The valves are engineered to maintain precise dimensional tolerances and durability under demanding engine operating conditions.
The TEVI-1047 specification includes:
- 31.5 mm valve head diameter
- 5.96 mm stem diameter
- 103.60 mm overall length
- Inconel material
- Single-groove configuration
Toyota 2RZ-FE and 3RZ-FE Engine Compatibility
These Supertech racing exhaust valves are designed for compatible Toyota 16-valve cylinder heads.
Toyota 2RZ-FE 2.4L
The 2RZ-FE is a four-cylinder petrol engine used in selected Toyota pickup applications.
The TEVI-1047 valves provide a +1 mm oversize exhaust valve option for performance engine builds.
Toyota 3RZ-FE 2.7L
The 3RZ-FE is a four-cylinder petrol engine used in selected Toyota Tacoma and other Toyota truck applications.
These valves are suitable for compatible 3RZ-FE cylinder heads that have been professionally prepared for the larger valve diameter.
The manufacturer lists Toyota Tacoma applications from 1995 to 2004.
Compatibility must be verified using the engine code and cylinder-head specification.
What Is Included?
The Supertech TEVI-1047-8 package includes:
8 × Supertech Inconel Exhaust Valves
Each valve measures 31.5 mm × 5.96 mm × 103.60 mm.
Valve springs, retainers, keepers, guides and valve stem seals are not included unless separately specified.
Professional Cylinder Head Preparation Required
These valves are not direct standard-diameter replacement parts.
Because the valve head diameter is increased by 1 mm, the cylinder head requires suitable valve-seat machining and inspection.
A qualified engine builder should check valve-to-seat contact, installed height, spring compatibility, valve-to-piston clearance and other relevant clearances.
Correct machining and assembly are essential for reliability.
