Long Cast Iron Cylinder Kit – Set of 4

Build the ultimate high-capacity Type 4 engine with this OE Match Long Cast Iron Cylinder Kit, designed for Volkswagen Type 4 engines fitted to the Porsche 914 and Porsche 912E.

Fits:

• Porsche 914 (1970-1976)
• Porsche 912E 4CYL 1976

Available in 103mm, 104mm or 105mm bore sizes, these premium cast iron cylinders are specifically manufactured for long stroke and long connecting rod engine builds. Each cylinder is 14.6mm longer than a standard Type 4 cylinder and is supplied ready to be cut to the required height, allowing engine builders to achieve the exact deck height for custom performance applications.

Manufactured from high-strength cast iron for exceptional durability and wear resistance, these cylinders are intended for serious performance and competition engines where precision and flexibility are essential.

Please Note:
Available in 103mm, 104mm and 105mm bore sizes. Both the cylinder heads and crankcase must be machined to accept the larger bore. Cylinders are 14.6mm longer than standard and are designed to be cut to fit for long stroke or long rod engine combinations. Professional engine machining and assembly are recommended.

What Do Engine Cylinders Do?

Engine cylinders provide the precision-machined bores in which the pistons travel, forming the combustion chambers that generate engine power.

Their primary functions include:

• Guiding piston movement
• Maintaining combustion chamber compression
• Providing a durable wear surface
• Dissipating combustion heat
• Supporting efficient engine operation and reliability

Cylinder accuracy is critical for achieving optimum compression, oil control and long-term engine performance.

Why Do Engine Cylinders Wear Out?

Engine cylinders are continually exposed to high temperatures, combustion pressures and piston movement throughout their service life.

Common causes of wear include:

• High mileage
• Poor lubrication
• Engine overheating
• Worn piston rings
• Dirt or debris entering the engine
• Detonation and excessive engine loads

As the cylinder bores wear, compression decreases, oil consumption rises and engine performance gradually deteriorates.

Why Upgrade to Long Big Bore Cylinders?

Long cylinders are specifically designed for custom Type 4 engine builds using long stroke crankshafts or longer connecting rods.

Their extended length provides engine builders with additional material that can be machined to achieve the precise deck height required for a particular engine specification.

Benefits include:

• Suitable for custom long stroke engines
• Compatible with long connecting rod combinations
• Allows precise deck height adjustment
• Available in 103mm, 104mm and 105mm bore sizes
• Increases engine capacity and performance potential
• Strong cast iron construction for maximum durability
• Ideal for high-performance road and motorsport engines

This flexibility makes them the preferred choice for bespoke engine builds where maximum performance and accurate engine geometry are essential.

When Should They Be Replaced?

Replacement or upgrading is recommended when:

• Cylinder bores are worn, tapered or scored
• Compression readings are below specification
• Oil consumption has increased significantly
• The engine is undergoing a complete performance rebuild
• A long stroke or long rod engine is being built
• Existing cylinders have suffered heat damage or corrosion

Installing a new long cylinder kit during an engine build provides the foundation for a reliable, high-performance Type 4 engine.

Porsche 914 & 912E Type 4 Performance Engine Components

When building a custom Type 4 engine, every component must work together to achieve the desired capacity, compression ratio and deck height. Long cylinders provide the flexibility required for stroked crankshaft and long connecting rod combinations, allowing experienced engine builders to machine the cylinders to the exact dimensions needed for a precision-built engine.

Manufactured from durable cast iron, these OE Match long cylinders are engineered for demanding applications where strength, reliability and accurate machining are essential. Whether you're building a powerful fast road engine or a dedicated competition motor, they provide the ideal foundation for a bespoke Type 4 build.
