High-Performance Forged Piston – Alfa Romeo 2000 Nord

Description

Certainly. Here’s the technical product description rephrased specifically for forged 4320 alloy pistons designed for Alfa Romeo Nord engines:

Forged Pistons – 4320 Alloy – Alfa Romeo 200 Nord Engines

High-performance forged pistons, precision-manufactured from 4320 nickel-chromium-molybdenum alloy, specifically engineered for Alfa Romeo NORD-series twin cam engines (1300, 1600, 1750, and 2000).

The use of 4320 alloy, renowned for its exceptional fatigue strength, toughness, and thermal stability, ensures these pistons withstand the extreme loads and elevated temperatures typical of racing and high-output applications. Closed-die forging improves structural uniformity and durability by aligning the grain flow along stress paths, significantly increasing resistance to failure under cyclic loading.

Key technical features:

• CNC-machined crowns tailored to the hemispherical Alfa combustion chamber
• Reinforced pin bosses for compatibility with heavy-duty piston pins
• Pressure accumulator grooves to stabilize ring pack performance at high RPM
• Anti-detonation bands to mitigate pre-ignition in aggressive tune setups
• Graphite or moly skirt coating to reduce drag and prevent cold-start scuffing
• Available with custom compression ratios and bore sizes (Ø84–Ø86mm)

Designed for naturally aspirated and forced induction NORD engines, including 105/115-series cars. These pistons are ideal for builds targeting increased displacement, higher compression, or competitive endurance performance.
