OE MATCH Pistons and cylinders

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.

• 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.

Fits: Porsche 356 C / SC 1963-66 & Porsche 912 1965 and Up with the 3 piece case.

JE Forgings are made from 2618 Aluminum, They have a 0 offset with extra material under the top for the valve pocket and the 30° Angle. This is a High Compression Piston kit 11.5:1 more commonly used in race-cars .

Engine size: 1600cc
Stroke: 74mm
Pistons: JE 2618 Forged
Dome Height: .295
Compression: 11.5:1
Piston Angle: 30°

Kit includes: 4 Pistons, A set Piston Rings, and 4 wrist pins and clips.

The forged construction provides excellent strength and durability under demanding operating conditions. Compared with conventional cast pistons, forged pistons are particularly suited to performance-oriented engine builds where increased cylinder pressures, higher temperatures, and elevated engine speeds may be encountered. The high-compression design is intended to increase the engine's compression ratio when combined with the appropriate cylinders, cylinder heads, deck height, and combustion chamber specification.

What This Product Does:

• Forms a critical part of the engine's combustion chambers.
• Contains combustion pressure within each cylinder.
• Transfers combustion force through the connecting rods to the crankshaft.
• Provides a big-bore configuration for compatible engine builds.
• Uses JE forged construction for increased strength and durability.
• Uses a high-compression design for compatible performance applications.
• Can contribute to increased engine displacement when used with the appropriate cylinders and engine configuration.
• Helps maintain effective cylinder compression and sealing when correctly installed.
• Provides a strong foundation for performance-oriented engine builds and rebuilds.
• Replaces worn, damaged, or unsuitable existing pistons.

Symptoms Of Wear Or Failure:

• Low or uneven cylinder compression.
• Excessive engine oil consumption.
• Blue smoke from the exhaust.
• Reduced engine power or poor performance.
• Excessive crankcase pressure or blow-by.
• Piston slap, knocking, or abnormal internal engine noises.
• Scoring or excessive wear on the piston skirts.
• Cracked, burnt, or damaged piston crowns.
• Worn, cracked, or broken piston ring lands.
• Excessive piston pin or pin-bore wear.
• Cylinder wall scoring or abnormal bore wear.
• Poor compression or leak-down test results.
• Evidence of detonation or piston crown damage.
  
  

Why Replacement Matters:

• Pistons are among the most highly stressed components inside an engine and are fundamental to compression, combustion, and power production. Worn piston skirts, damaged ring lands, cracked crowns, excessive clearances, or other piston defects can compromise cylinder sealing and lead to reduced performance, increased oil consumption, excessive blow-by, abnormal noise, and accelerated internal engine wear.
• Correct component selection and engine setup are especially important with big-bore high-compression forged pistons. Increasing bore size or compression can significantly change combustion characteristics and mechanical clearances. Incorrect compression ratio, ignition timing, fuel specification, piston clearance, deck height, or piston-to-valve clearance can contribute to detonation, overheating, piston damage, or severe engine failure.
• Replacing worn components or building a compatible performance engine with the correct OE Match Big Bore JE Forged High Compression Piston Set – 0081182JEP or 0081183JEP provides a strong foundation for increased performance and dependable operation. JE forged construction offers the strength required for demanding applications when the engine is correctly specified, machined, tuned, and assembled.
