Most pistons are in-stock; custom pistons typically take about four weeks; coatings and additional engineering may add one to two weeks extra to manufacturing of your custom JE Pistons. Where possible, we design our JE Pistons to accept OE Porsche Goetze rings and ensure that any rings supplied are the best possible for any given bore size or application.
Porsche 356 90mm JE Piston shown with all standard upgrades as well as optional lighten combo, mill under crown, and thermal barrier coating. Also available in 19mm wrist pin size for use with R&R Pro Billet connecting rods for Porsche 356 models.
All LN Engineering's forged JE Pistons are designed to work with any cylinder kit, but perform the best when paired with our very own Nickies™ cylinders: The Original Solid Aluminum CNC Billet NSC-Plated Cylinders for Porsche and Volkswagen. Where a Mahle piston best suits a Mahle cyliner, the proprietary alloy used for our Nickies™ cylinders is designed for optimal piston to cylinder clearance using JE's forgings.
Good quench allows for faster burn and better thermal efficiency, leading to
better gas mileage, lower potential for detonation, and more power. Whatever the case, here’s the bottom line: we work with you to provide ideal pistons and cylinders for your application, period.

Our
custom forged pistons are the best
of their kind.
The “Ultra-quench” dish shape design as shown above and to the left
mimics the shape of the combustion chamber and is sized to allow the
compression ratio you want while maintaining optimal .040-.060” deck height for
maximum quench, as with all our pistons. This results in a faster burn for better thermal efficiency,
leading to better gas mileage, lower potential for detonation, and best of
all, more power, and are exclusive to LN, available for the VW Type 1 and Type4.
