Engine size: 2000cc
Stroke: For use with 71mm to 78mm Crankshafts
Pistons: Hypereutectic aluminium alloy
Compression Height: 35.50mm
Pin: 24mm

Set includes: 4 pistons, 4 pins and a set of rings

The piston set converts combustion pressure into rotational force by transferring energy through the connecting rods to the crankshaft. The flat top piston design promotes efficient combustion while maintaining the intended compression ratio for compatible engine builds, ensuring smooth power delivery and reliable engine operation. Over time, pistons can suffer from wear caused by excessive heat, friction, detonation, or inadequate lubrication, resulting in piston slap, cracked ring lands, excessive oil consumption, reduced compression, and declining engine performance. Replacing worn pistons restores engine efficiency, reliability, and smooth operation.  

What This Product Does:

• Converts combustion pressure into crankshaft rotation.
• Restores engine compression and combustion efficiency.
• Supports smooth piston movement within the cylinders.
• Provides reliable sealing when used with new piston rings.
• Improves engine performance and reduces oil consumption.
• Replaces worn, damaged, or heat-affected pistons.
• 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.
• Piston slap or knocking noises.
• Loss of engine power or acceleration.
• Damaged piston crowns or cracked ring lands.
• Excessive cylinder blow-by.
• Damage identified during engine overhaul.

Why Replacement Matters:

• The pistons are among the most heavily loaded components within the engine, converting combustion energy into mechanical power while maintaining compression and efficient combustion. Worn or damaged pistons reduce engine performance, increase oil consumption, create excessive blow-by, and accelerate wear throughout the engine. Replacing pistons during an engine rebuild restores correct operating clearances and supports reliable long-term performance.
• Replacing worn pistons with this OE Match Flat Top Piston Set restores engine compression, improves combustion efficiency, reduces oil consumption, and delivers dependable engine performance. Manufactured as a direct replacement and produced to OE-style specifications, this OE Match Flat Top Piston Set, 96 x 71mm provides reliable fit, performance, and durability for classic Porsche engine maintenance, performance upgrades, repairs, and restoration projects.
