JE Forged Piston Set, SET OF 6. Porsche 911S 2.2L / 2.4L › 0089118

This OE Match set contains six JE forged pistons for Porsche 911S 2.2L and 2.4L engines. Rings, six gudgeon pins and retaining clips accompany the pistons.

Fits

• Porsche 911S 2.2L / 2.4L
  
  

The broader application grouping above does not replace the specific 911S engine application. Check fitment for your specific vehicle (model, year, engine) before ordering.

What This Product Does

Pistons receive combustion pressure and pass that force through the connecting rods to the crankshaft. Together with correctly fitted rings and suitable cylinder bores, they help maintain compression and manage oil at the cylinder wall.

Functions

• Transmit combustion force to the connecting rods.
• Support cylinder sealing through the piston rings.
• Provide the piston crown and valve-pocket geometry required by the selected engine specification.
  
  

Technical Details

• JE forgings use 2618 aluminium alloy, with zero offset and additional material beneath the crown for valve pockets.
• Engine capacity: 2.2L / 2.4L; crankshaft stroke specifications: 66mm / 70.4mm.
• Contents: six pistons, piston rings, six gudgeon pins and retaining clips.
• 84mm high-compression option: 10.1:1 compression with a 66mm crankshaft stroke; 10.6:1 with a 70.4mm stroke.
• 86mm low-compression option: 9.2:1 compression with a 66mm crankshaft stroke; 9.5:1 with a 70.4mm stroke.
• 86mm high-compression option: 10.5:1 compression with a 66mm crankshaft stroke; 11.2:1 with a 70.4mm stroke.
  
  

Symptoms of Fault

• Compression readings that are low or differ between cylinders.
• Increased oil use, exhaust smoke or excessive crankcase blow-by.
• Cold-running piston slap or persistent internal knocking.
• Scored skirts, damaged crowns or fractured ring lands found during inspection.
• Metal particles discovered in the lubricant or filter.
  
  

These findings require diagnosis; they do not establish piston failure on their own.

Why Replacement Matters

Worn or damaged pistons may no longer seal correctly against their cylinder bores. During rebuilding, assess piston condition alongside bore measurements, ring condition and lubrication. Investigate overheating, detonation or oil-supply problems before assembly rather than replacing damaged components without addressing the cause.

FAQs

Which option should I choose?
Match the piston diameter and compression specification to the measured cylinders, crankshaft stroke and intended engine build. Do not select solely by engine capacity.

Are cylinders included?
The stated contents cover pistons, rings, pins and clips; cylinders are not listed.

What checks should precede installation?
Have an engine specialist confirm bore condition, piston-to-cylinder clearance and ring fit, and inspect the associated bearings and oil supply.
