GSC 4B11 Evo X Intake Valves

Description

GSC 4B11 Evo X Intake Valves

Firstly, BUY GSC 4B11 Evo X Intake Valves for Mitsubishi Evolution X 4B11T engines, Upgrade or rebuild your Mitsubishi Evolution X 4B11T cylinder head with GSC 4B11 Evo X Intake Valves, engineered for performance-focused engine builds, cylinder-head rebuilds, and demanding turbocharged applications. Manufactured by GSC Power-Division, these performance intake valves are designed specifically around the 4B11T Evo X platform and are available in standard 35mm and +1mm oversized 36mm configurations.

The intake valve is a critical component of the 4B11T valvetrain. It controls the entry of air into the combustion chamber and must maintain accurate movement, sealing, and durability as engine speed, boost pressure, and cylinder pressure increase. For Evo X owners building a stronger cylinder head, replacing worn valves, or preparing an engine for increased performance, choosing quality performance valves can be an important part of the overall build.

GSC 4B11T Intake Valve Options

GSC offers two primary intake valve sizes for the Mitsubishi Evolution X 4B11T:

Configuration	Head Diameter	Part Number	Quantity
Standard Size	35mm	GSC2022-8	Set of 8
Standard Size	35mm	GSC2022-01	Single
+1mm Oversize	36mm	GSC2024-8	Set of 8
+1mm Oversize	36mm	GSC2024-01	Single

The standard-size GSC2022 intake valve uses a 35mm head diameter, while the GSC2024 +1mm version increases the head diameter to 36mm. Both versions use a 5.5mm valve stem and have an overall length of 113.15mm.

Standard 35mm Intake Valves

The GSC2022 standard-size intake valves are an excellent choice for Evo X 4B11T cylinder-head rebuilds where the factory-size intake valve diameter is preferred. They can be used when replacing worn or damaged valves or when assembling a performance-oriented cylinder head while retaining the standard valve diameter.

The standard 35mm configuration is particularly useful for builders who want a straightforward performance-valvetrain replacement without moving to an oversized intake valve setup.

+1mm 36mm Intake Valves

For more extensively prepared cylinder heads, GSC also offers the GSC2024 +1mm intake valve with a 36mm head diameter. The additional valve diameter can be incorporated into a properly prepared cylinder head to support increased airflow potential.

Because the 36mm valve is oversized compared with the standard 35mm configuration, proper cylinder-head machining and valve-seat preparation are important before installation. This option is best suited to engine builders who are deliberately upgrading the cylinder head rather than simply replacing standard-size valves.

Performance-Focused GSC Valve Design

GSC Power-Division states that its performance valves are developed using 3D design and simulation processes, with prototype valve heads flow tested for the specific application. The design incorporates features intended to improve airflow and reduce valve weight and distortion.

The intake valves feature swirl-polished heads designed to promote smoother airflow across the valve. GSC also uses a back-cut design to reduce valve weight, which can be beneficial for high-RPM applications and aggressive camshaft configurations.

The valve stems are micro-polished to reduce friction between the valve stem and guide. GSC specifies modified 21-4N stainless material for its intake valves, while the valve tips and keeper-groove design are developed to support proper valvetrain durability and geometry.

Why Upgrade Your Evo X Intake Valves?

Firstly, quality intake valves are essential when rebuilding a 4B11T cylinder head. Worn, damaged, or compromised valves can affect sealing and combustion performance, making valve replacement an important consideration during a serious engine rebuild.

Secondly, GSC provides both standard and oversized configurations. This allows engine builders to select the valve size that best matches their cylinder-head machining, airflow goals, and overall engine combination.

Thirdly, these valves are suited to performance-oriented Evo X builds where the cylinder head needs components capable of handling increased RPM, boost, and demanding operating conditions.

For a complete cylinder-head build, consider pairing these intake valves with compatible GSC valve springs, retainers, valve guides, and valve stem seals. GSC also offers dedicated 4B11T valvetrain components for the Evolution X platform.

Evo X 4B11T Fitment

These GSC intake valves are designed for the Mitsubishi Lancer Evolution X equipped with the 4B11T turbocharged engine. GSC identifies the application as the Evo X 4B11T, including the 4B11T Evo 10 Dual MIVEC application.

Always verify the exact valve size and GSC part number before ordering, particularly when choosing the +1mm 36mm configuration. Oversized valves require the appropriate cylinder-head and valve-seat preparation.

Frequently Asked Questions

What size are GSC 4B11 Evo X intake valves?

GSC offers standard-size 35mm intake valves and +1mm oversized 36mm intake valves for the Evo X 4B11T.

What is the valve stem diameter?

Both configurations use a 5.5mm valve stem diameter and have an overall length of 113.15mm.

What is the standard GSC 4B11 intake valve part number?

The standard 35mm intake valve is GSC2022, with GSC2022-8 being the set of eight.

What is the +1mm intake valve part number?

The +1mm 36mm intake valve is GSC2024, with GSC2024-8 being the set of eight.

Are these valves suitable for a high-performance Evo X?

Yes. GSC develops these valves specifically for performance applications, with design features intended to support airflow, reduced valve weight, durability, and high-RPM operation.

Do the 36mm +1mm valves require machining?

Yes. Since the 36mm intake valve is larger than the standard 35mm valve, the cylinder head and valve seats should be properly prepared by a qualified engine builder before installation.
