Cylinder Kit, Big bore VW 86mm.
Increase engine capacity and restore dependable performance with this OE Match Big Bore VW 86mm Cylinder Kit. Produced to OE-style specifications, this precision-engineered Big Bore cylinder kit is designed for compatible classic Volkswagen air-cooled engines and Porsche applications using the same engine platform where applicable. Manufactured from high-quality cast materials with precision-machined cylinder bores, the kit delivers exceptional durability, excellent heat dissipation, and reliable sealing under demanding operating conditions. The larger 86mm bore increases engine displacement, making it ideal for performance engine builds, complete engine rebuilds, and restoration projects.

Fits:

• Porsche 911 1965-1968 2.0L / 912 SWB (F)
• Porsche 356 1950-55
• Porsche 356A 1955-59
• Porsche 356B 1959-63
• Porsche 356C 1963-65  

The cylinder kit forms the combustion chamber walls, providing the precision-machined surfaces required for the pistons and piston rings to generate efficient compression and combustion. The increased 86mm bore enlarges engine displacement, allowing greater air and fuel volume to enter the cylinders, which can improve torque and overall engine performance when used with compatible components. Over time, cylinder bores can become worn, scored, tapered, or distorted through continual piston movement, heat cycles, and normal engine wear, resulting in reduced compression, increased oil consumption, and declining performance. Replacing worn cylinders restores engine efficiency while providing the performance benefits of a Big Bore configuration.  

What This Product Does:

• Provides precision-machined cylinder bores for the pistons.
• Increases engine displacement with an 86mm bore.
• Restores engine compression and combustion efficiency.
• Supports correct piston and piston ring operation.
• Improves engine performance and torque potential.
• Replaces worn, scored, or damaged cylinders.
• Provides an OE-style fit for straightforward engine rebuilding.

Symptoms Of Wear Or Failure:

• Low engine compression.
• Excessive oil consumption.
• Blue exhaust smoke caused by oil burning.
• Loss of engine power or performance.
• Excessive crankcase blow-by.
• Scored, worn, or tapered cylinder bores.
• Piston slap or abnormal engine noise.
• Damage identified during engine overhaul.

Why Replacement Matters:

• The cylinders are fundamental to maintaining engine compression, efficient combustion, and reliable piston movement. As cylinder bores wear, engine performance declines, oil consumption increases, and internal engine wear accelerates. The 86mm Big Bore design increases engine displacement, offering greater performance potential while restoring the engine's ability to operate efficiently and reliably.
• Replacing worn cylinders with this OE Match Big Bore 86mm Cylinder Kit restores compression, reduces oil consumption, improves engine performance, and supports long-term engine reliability. Manufactured as a direct replacement and produced to OE-style specifications, this OE Match Big Bore VW 86mm Cylinder Kit provides reliable fit, performance, and durability for classic Volkswagen and compatible Porsche engine maintenance, performance upgrades, repairs, and restoration projects.
