HKS Cylinder Liner

1991–1993 Nissan Silvia SR20DET 2.0L

Part #: 2399-RN001

Overview

The HKS Cylinder Liner for the Nissan Silvia SR20DET is a high-performance ductile iron piston sleeve designed to enhance the durability and performance of your engine, especially in high-horsepower applications. Built for enthusiasts who are pushing their SR20DET motors beyond stock limits, these sleeves provide a reliable solution for rebuilding and strengthening your engine block.

If you're building a race motor or seeking to support horsepower levels over 500+ hp, these cylinder sleeves are an essential upgrade. They help prevent cylinder wear and deformation under extreme conditions, ensuring your engine maintains optimal compression and efficiency during spirited driving or competitive racing.

Designed with precision and durability in mind, the HKS sleeves are ideal for custom engine builds where bore reinforcement is critical. Please note that proper installation requires machining, as these sleeves are not compatible with stock 86mm or aftermarket 86.5mm pistons without bore adjustments.

Key Features

The HKS Cylinder Liner offers several key features that make it a top choice for high-performance SR20DET builds:

• Constructed from high-quality ductile iron, providing excellent strength and wear resistance for demanding racing conditions.
• Designed with .87mm piston-to-bore clearance, ensuring optimal fitment and thermal expansion management for high-horsepower engines.
• Engineered specifically for the Nissan Silvia SR20DET (1991–1993), ensuring precise fitment and compatibility.
• Ideal for engines being built from the ground up, offering reinforcement where the stock block may be insufficient under extreme power levels.
• Supports high-performance applications, including turbocharged setups exceeding 500 horsepower.
• Requires machining of the engine block for proper installation, as sleeves do not work with stock or 86.5mm pistons without bore adjustments.
• Designed to improve engine longevity and reliability during high-stress racing or tuning scenarios.

Construction & Design

The HKS cylinder sleeves are crafted from ductile iron, a material known for its exceptional toughness and resistance to fatigue. The sleeves are precision-machined to exact specifications, ensuring a perfect fit within the engine block after proper boring and honing. Their design includes a .87mm piston-to-bore clearance, which balances thermal expansion and piston stability, critical for high-performance engines.

The sleeves are intended for professional installation, requiring a machine shop to bore the block to the correct diameter and install the sleeves securely. This process ensures a tight, leak-free seal and optimal engine performance. The use of ductile iron enhances durability, making these sleeves suitable for engines subjected to high boost pressures and aggressive tuning.

Installation & Fitment

The HKS Cylinder Liner is a race-oriented component that requires professional installation. The engine block must be bored to the specified diameter to accommodate the sleeves, which involves precise machining. No cutting, drilling, or tuning is required beyond the machining process, but the installation should be performed by experienced engine builders to ensure proper fitment and sealing.

Once installed, these sleeves provide a reinforced cylinder wall capable of handling high boost pressures and aggressive tuning, making them ideal for race engines or heavily modified street cars.
