Planning a stronger Volkswagen or Audi 2.0T TSI build for increased boost, a larger turbocharger, or demanding street and track driving? The JE Pistons Forged Piston Kit, part number 345814, provides a performance-focused alternative to factory-style pistons for compatible 22mm wrist pin engines. Manufactured in the USA from 2618 forged aluminum, these pistons are designed for the elevated cylinder pressures and demanding operating conditions found in modified turbocharged engines.
With an 83.00mm bore, 9.6:1 nominal compression ratio, and -7.80cc dished crown, this kit is suited to properly machined 2.0T TSI short blocks requiring a 0.50mm overbore. JE uses a round forging design with accumulator grooves to support piston ring stability, precision wrist pin fitting for accurate assembly, and a smooth crown finish to reduce potential stress concentrations and hot spots. The complete set includes four forged pistons, JE Pro Seal rings, wrist pins, and retaining locks, giving builders the essential piston components for a carefully planned performance engine.

Volkswagen and Audi's 2.0T engines are popular choices for turbocharger upgrades, but increased boost also puts additional stress on the pistons and rotating assembly. Once you're planning a more demanding engine setup, forged pistons become an important consideration.
JE manufactures these pistons from 2618 aluminum alloy, selected for its strength and ductility under demanding combustion conditions. This makes them a performance-oriented option for enthusiasts rebuilding a damaged engine or assembling a stronger bottom end for future modifications.
The 83.00mm bore is particularly useful when rebuilding an engine that requires cylinder machining beyond the original 82.50mm diameter. Rather than returning to a standard-bore piston, this kit allows the engine builder to work with a properly finished 0.50mm overbore.
Maintaining effective piston ring sealing becomes increasingly important as cylinder pressure rises.
JE's accumulator groove provides additional volume between the top and second compression rings. This helps reduce pressure buildup from gases that pass the top ring, minimizing ring flutter and supporting consistent sealing during high-load engine operation.
It's a useful feature for turbocharged engines that regularly experience elevated combustion pressure.
The smooth crown finish removes sharp edges around the piston crown and valve relief areas.
These refinements help reduce potential hot spots and stress concentrations, which are important considerations when building an engine intended to operate under demanding thermal and combustion conditions.
Unlike JE's skirt-coated FSR piston configurations, part 345814 uses a round forging design with a smooth crown finish and does not list a skirt coating.
The wrist pin bores are precision-honed to provide controlled clearance between the pistons and pins. JE identifies typical pin-to-bore clearances of 0.0003 to 0.0010 inches, with final installation dimensions established during engine assembly.
The included 5115 case-hardened steel wrist pins measure 0.866 inches in diameter, corresponding to the 22mm configuration required by this kit.
With JE Pro Seal piston rings and retaining locks included, part 345814 provides a complete four-piston package for a properly engineered 2.0T TSI performance rebuild.
Fitment & Installation Notes:
Volkswagen / Audi 2.0T TSI: Designed for compatible engines using the 22mm wrist pin configuration.
Engine Application: JE identifies a 2013-2015 2.0T TSI engine configuration with 22mm wrist pins. Confirm the exact engine code and internal dimensions before ordering.
Required Finished Bore: 83.00mm.
Overbore: +0.50mm compared with the standard 82.50mm bore.
Compression Ratio: Nominal 9.6:1 for the intended engine geometry. Final compression depends on the cylinder head, gasket thickness, and deck clearance.
Piston Configuration: -7.80cc dished crown with 1.165-inch compression height.
Wrist Pin Diameter: 0.866 in., approximately 22mm.
Connecting Rod Compatibility: Verify the connecting rod small-end design. Compatible aftermarket connecting rods with non-tapered 22mm wrist pin ends may be required.
Cylinder Machining: Measure the actual pistons and finish the cylinders to JE's recommended piston-to-wall clearance.
Piston Ring Installation: Measure and adjust ring end gaps according to JE's instructions and the intended boost, fuel, and operating conditions.
Piston-to-Valve Clearance: Confirm clearance during assembly, particularly when using modified cylinder heads or aftermarket camshafts.
Engine Calibration: Fuel delivery, ignition timing, boost control, and ECU tuning should match the completed engine build.
Horsepower Rating: No fixed horsepower rating is specified for part 345814. Engine capability depends on the complete assembly, supporting components, and tuning.
For VW and Audi enthusiasts rebuilding a 2.0T TSI or preparing for more demanding turbocharged performance, the JE Pistons 345814 kit combines American-made forged 2618 aluminum construction, a 9.6:1 compression configuration, accumulator grooves, smooth crown finishing, and precision wrist pin fit in a complete four-cylinder piston package.
