Mazda MX-5 NC/MK3 Clutch Pedal and Master Relocation kit

Description

Engineered for Clearance. Defined by Flow.

If you are running a turbocharged 2.0L or 2.5L powerplant with the Kraken.EU manifold, you are familiar with the “bottleneck” dilemma. Attempting to shoehorn a proper 3” downpipe against the firewall is nearly impossible with the bulky OEM clutch master cylinder occupying that critical space.

While most builders compromise with a restrictive 2.5” downpipe, our Clutch Master Cylinder Relocation Kit removes the obstacle entirely, allowing you to prioritize exhaust flow and turbocharger efficiency.

The 3” Advantage: Unrestricted Spool & Power

In high-boost applications, every millimeter of exhaust diameter counts. A 3” downpipe significantly reduces backpressure, facilitating earlier spool times and higher peak power ceilings compared to standard 2.5” alternatives. We’ve engineered the solution that makes this “absolute maximum” fitment a reality.

Bespoke Interior-Facing Architecture

We have eliminated the engine-bay footprint of the clutch hydraulics altogether. By redesigning the pedal assembly, the master cylinder is now relocated to the interior of the cabin, facing inwards.

• Maximum Clearance: Opens the firewall area completely for 3” downpipe routing.

• Thermal Isolation: By moving the cylinder and lines inside the cabin and exiting the high-pressure line via the passenger side (RHD), the hydraulic system is shielded from the immense radiant heat of the exhaust.

Enhanced Hydraulic Integrity

This kit does more than just move components; it upgrades the entire hydraulic strategy:

• Independent Reservoir System: We’ve transitioned from the shared factory brake/clutch reservoir to a dedicated, independent clutch reservoir. This thermally isolates the two circuits and prevents cross-contamination.

• Integrated Mounting: The new reservoir sits securely in front of the OEM brake reservoir using a precision-engineered bracket. The original feed is safely blanked off, ensuring a professional, leak-free conversion.

Precision Partnership: OBP Pedal Assembly

At the heart of this kit is a custom-spec pedal assembly manufactured by OBP Pedals. This competition-grade hardware features:

• CNC T6061 Aluminum Pedal Arm: Lightweight, high-strength construction for consistent pedal feel.

• Adjustable Foot-Plate: Allows for ergonomic fine-tuning to suit the driver’s preference.

• Increased Bore Diameter: Utilizes a compact, large-bore master cylinder to ensure crisp, decisive clutch engagement even with heavy-duty pressure plates.

What’s Included: The Definitive Kit List

Pedal & Master Cylinder Assembly

• OBP Custom Pedal Box: Interior-facing configuration with CNC T6061 Aluminum arm.

• Compact Master Cylinder: High-flow, large-bore unit for superior hydraulic leverage.

Hydraulic Routing & Management

• Independent Clutch Reservoir: High-temp polymer reservoir with bespoke mounting bracket.

• High-Pressure Line Kit: Braided lines designed for RHD passenger-side exit, keeping fluid away from the turbo manifold.

• Block-Off Hardware: Specialized bung to seal the factory brake reservoir feed.

Hardware & Finish

• Stainless Steel Fasteners: Corrosion-resistant mounting hardware for the reservoir and pedal assembly.

• Firewall Pass-throughs: Professional-grade seals to maintain cabin integrity.

Installation Requirements

• Compatibility: Optimized specifically for RHD vehicles utilizing Kraken.EU turbo manifolds.

• Pro-Tip: Ensure the new high-pressure line is routed with a natural sweep through the passenger-side firewall to maintain the “Twist-Free” integrity of the hydraulic circuit.

• Safety Warning: A full system bleed is required post-installation. We recommend high-boiling-point racing fluid to complement the kit’s thermal isolation capabilities.
