Mazworx 2JZ-GTE Stage 1 Cylinder Head

The Mazworx 2JZ-GTE Stage 1 Cylinder Head delivers a precision-built solution for Toyota 2JZ engine enthusiasts seeking reliability and performance. Crafted using advanced CNC machining and rigorous quality processes, each cylinder head is prepared meticulously to ensure a ready-to-install component that meets exacting standards.

Key Features

• Thorough Cleaning: The cylinder head undergoes a comprehensive hot tank cleaning to remove oil and grime, followed by sand blasting to eliminate corrosion and present a uniform satin aluminum finish.
• Oil Port and Freeze Plug Service: Oil port plugs are removed, re-tapped, and reinstalled to facilitate thorough cleaning of oil galleries. Freeze plugs are also removed and replaced to maintain system integrity.
• Port and Polish Stage 1: This step involves blending the seat and bowl areas while retaining the OEM casting for the remainder of the port, improving airflow without aggressive modification.
• EGR Port Modification: The EGR port is fully plugged with aluminum rod and smoothly ported to enhance flow and prevent exhaust gas recirculation interference.
• Valve Guide Replacement: Valve guides are removed, re-installed, and reamed, then replaced with high-quality Supertech bronze guides for durability and precision.
• Multi-Angle Valve Job: Optional upgrade involving cutting multiple angles on the valve seat to improve airflow efficiency.
• Head Surfacing: Precision resurfacing is performed using a poly-crystalline diamond (PCD) tool to ensure a flat sealing surface.
• Valve Seals and Assembly: Old valve seals are replaced with new Viton seals, followed by assembly with valves, springs, and retainers set to camshaft specifications.

Included Parts

• Supertech Standard Size Valves
• Supertech Titanium Retainers
• Supertech Dual Valve Springs (80lb)
• Supertech Bronze Valve Guides
• Viton Valve Seals
• Oil Port Pipe Plugs
• Freeze Plugs

Core Requirements

• Cylinder Head with Cam Caps (customer supplied or select new OEM core)
• OEM Buckets

Additional Options and Recommendations

• Core Submission: Customers can send their existing head for machining or purchase a new OEM core. For Variable Valve Lift (VVL) heads, cores are sourced from complete motors. Additional parts can be requested with the head.
• Valve Springs and Retainers: Selection between spring and retainer sets is available to suit different applications.
• Camshaft Recommendations: Kelford 184-T cams are suggested for high-RPM turbo applications. For race engines, removing the VVL lobe reduces valvetrain mass and improves bottom-end oil supply at high RPMs.
• Hall Sensor Machining: Available machining to accept Hall Effect Sensor Kits.
• 1/2″ Head Stud Machining: For power outputs above 600hp, machining for 1/2″ head studs including dowel pin re-location is recommended to accommodate stronger fasteners.

This Stage 1 cylinder head build from Mazworx combines precision machining, high-quality components, and tailored assembly to deliver a reliable foundation for your 2JZ-GTE engine upgrades.
