R56 N14 Sneed Forged Race Series Piston Set — OEM Size 77.00 mm
Overview
The R56 N14 Sneed Forged Race Series Piston Set — OEM Size 77.00 mm is a performance-grade piston upgrade engineered by SneedSpeed for R56 MINI Cooper S models with the turbocharged N14 engine. These forged pistons are built to handle greater loads and elevated thermal stress compared with standard pistons, making them well suited for high-performance street, track, or race-oriented builds.
Purpose & Application
This piston set is designed as a direct replacement for the factory pistons in the N14 turbo engine with 77.00 mm bore size, enabling a precision fit without machining modifications. Whether you’re rebuilding an engine or upgrading for increased performance, these forged pistons provide enhanced strength, durability, and response for demanding use cases.
Key Features
-
OEM-Size 77.00 mm Fitment: Installed as a direct replacement for the stock pistons with exact sizing to original specification for straightforward installation.
-
High-Strength Forged Construction: Machined from premium aluminum alloy with a forging process that increases material integrity and resistance to fatigue under load.
-
Performance-Oriented Design: Optimized piston crown and skirt profiles improve combustion efficiency and reduce drag within the cylinder to support consistent power delivery.
-
Advanced Surface Coating: Engineered surface treatments reduce friction and improve heat resistance for more consistent performance under elevated temperatures.
-
Lightweight Yet Durable: Maintains low reciprocating mass to support quicker engine response without sacrificing strength or reliability.
Performance Benefits
-
Enhanced Load Capacity: Forged pistons provide greater strength against increased cylinder pressures typical of performance tuning and sustained high-RPM operation.
-
Improved Thermal Stability: Refinement in material and design helps resist distortion and maintain performance under elevated heat conditions.
-
Smooth Operation: Precision machining and design support consistent power delivery and reduced internal friction.
Ideal Build Scenarios
-
High-Performance Street Builds where stronger pistons ensure longevity under spirited driving
-
Track and Competition Engines requiring pistons capable of handling repeated high loads
-
Engine Rebuilds Where Reliability Is Critical and OEM components no longer meet performance needs
