VTI Forged Piston & Ductile Iron Liners Kit – Twin Spark 8V – Performance Rebuild

Description

Technical Product Description:

High-performance piston and cylinder liner kit specifically engineered for Alfa Romeo Twin Spark 8V engines, designed for competition and performance street applications.

This kit combines forged 4320 alloy pistons with advanced ductile iron cylinder liners — offering superior mechanical properties compared to conventional CrMo alloy sleeves.

The ductile iron liners provide excellent tensile strength, wear resistance, and fatigue life under extreme thermal and mechanical loads, making them ideal for engines operating under high cylinder pressures and temperatures.

Kit Contents:

• Forged Pistons (4320 Alloy): Ø85mm bore, forged from high-strength Ni-Cr-Mo alloy, featuring reinforced pin bosses, CNC-machined crowns, and graphite-coated skirts for reduced friction and enhanced scuff resistance
• Ductile Iron Cylinder Liners: High-performance sleeves with superior structural integrity and exceptional wear resistance, designed to outperform standard CrMo alloy liners under high stress
• Piston Rings: High-tension performance ring set included, pre-gapped for standard applications
• Piston Pins & Locks: Heavy-duty floating wrist pins with locking clips for secure installation

Key Features:

• Suitable for both naturally aspirated and forced induction Twin Spark 8V engines
• Direct-fit replacement for Alfa Romeo 2.0 Twin Spark (8-valve) engines
• Ductile iron liners offer enhanced durability, better heat dissipation, and longer service life in high-output engines
• Custom compression ratios and bore sizes available on request
• Designed for high-performance rebuilds, racing, and demanding street applications

Recommended for: Engine builders and performance specialists seeking maximum reliability, high compression capability, and improved long-term durability in Twin Spark-powered applications.

Note: Custom machining services and piston compression ratio adjustments available upon request.
