JE Pistons

JE Piston - Set of 6
Forged from 4032 Aluminium Alloy



Fits:
Porsche 911 3.2ltr (10.0:1)

Engine Size : 3.2ltr
Bore Size: 98.00mm
Stroke: 74.40mm
Rod length: 127.00mm
Compression Distance : 32.77mm
Compression Ratio: 10.0:1
Oversize: 3.00mm
Material: 4032 Aluminium Alloy

JE designs are specifically engineered for extreme applications up to and including professional competition. In this environment, the higher compression ratios, high boost or heavy nitrous use necessitate the higher tensile strength of 4032 and 2618 aluminium alloy, which has been optimized for aftermarket Nikasil cylinders. The JE Piston Porsche series now include low friction skirt coatings and are lighter than before, improving both performance and longevity.

The Dome/Dish require no deburring or preparation and feature a smooth flowing radii for excellent flame travel.

4032 Aluminium Alloy
Pistons manufactured from 4032 wrought aluminium alloy are designed for high performance applications where a strong and quiet piston is required. These pistons require less initial piston to cylinder wall clearance and are quieter at start-up. Ideal for street/road use

Piston Features:
• Accumulator Grooves
• Contact Reduction Grooves
• Double Broach Oilers
• Skirt Coating
• Under crown Milling for Weight Reduction
• Pin Fitting, Wire Locks and Rings Included

JE Piston - Set of 6
Forged from 2618 Aluminium Alloy



Fits:
Porsche 911 3.2L 12V (10.5:1)

Engine Size : 3.2
Bore Size: 95.00mm
Stroke: 74.40mm
Rod length: 127.00mm
Compression Distance : 32.80mm
Compression Ratio: 10.5
Dome volume: 41.7cc
Oversize: STD

Designed for Porsche Air-cooled 911 engines compatible with a Nickel Ceramic bore, these pistons are machined from forged 2618 alloy for greater strength. The valve pockets are machined to accommodate high lift cams, and accept the stock stroke and rod length. The ring grooves are precision CNC machined and all new applications include skirt coating and 3D undercrown milling. Piston clearances designed for aluminum cylinders, steel/iron cylinders may require additional clearance.

2618 Aluminium Alloy
Pistons manufactured from 2618 wrought aluminium alloy are designed for racing and very demanding applications. These environments necessitate the higher strength 2618 aluminium alloy. When exposed to heat, 2618 aluminium alloy expands 15% more than 4032 aluminium alloy therefore the initial piston to cylinder wall needs to be 15% greater. This difference is most noticeable during cold start. When running at operating temperature both 2618 and 4032 pistons have approximately the same clearances.  

Includes:
• Accumulator Grooves
• Skirt Coating
• 3D Lightweight Undercrown Milling
• Pin fitting and wire locks
• 9310 high carbon alloy or tool steel wrist pins
• Rings Included
