Cylinder kit, Biral VW 82.5mm. Porsche 356/912  ❭  0081182BL

Cylinder Kit, Biral VW 82.5mm.
Restore or upgrade your engine with this OE Match Biral VW 82.5mm Cylinder Kit. Produced to OE-style specifications, this premium Biral cylinder kit is designed for compatible classic Volkswagen air-cooled engines and Porsche applications using the same engine platform where applicable. Featuring cast iron cylinder liners bonded to aluminium cooling fins, Biral cylinders combine the excellent wear resistance of cast iron with the superior heat dissipation of aluminium. Manufactured to precise tolerances, the kit delivers outstanding durability, efficient cooling, and consistent engine performance, making it ideal for engine rebuilds, performance upgrades, and concours-quality 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 in conjunction with the pistons and piston rings, providing the precision sealing surfaces required for efficient compression and combustion. The Biral construction offers improved thermal management compared with conventional cast iron cylinders, helping to maintain stable operating temperatures under demanding conditions. Over time, cylinder bores can become worn, tapered, scored, or distorted due to heat and continual piston movement, resulting in reduced compression and increased oil consumption. Replacing worn cylinders restores engine efficiency and long-term reliability.  

What This Product Does:

• Provides precision-machined cylinder bores for the pistons.
• Restores engine compression and combustion efficiency.
• Combines cast iron wear resistance with aluminium cooling.
• Improves heat dissipation for stable engine temperatures.
• Supports correct piston and piston ring operation.
• 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 engine performance, providing the precision-machined surfaces required for effective piston sealing and efficient combustion. As cylinder bores wear, engine compression decreases, oil consumption increases, and overall performance suffers. Biral cylinders offer the additional benefit of superior cooling performance, helping to reduce operating temperatures while maintaining excellent wear characteristics.
• Replacing worn cylinders with this OE Match Biral 82.5mm Cylinder Kit restores engine compression, improves cooling efficiency, reduces oil consumption, and supports long-term engine reliability. Manufactured as a direct replacement and produced to OE-style specifications, this OE Match Biral Cylinder Kit provides reliable fit, performance, and durability for classic Volkswagen and compatible Porsche engine maintenance, performance upgrades, repairs, and restoration projects.
