JE Pistons FSR Forged Piston Kit for VW/Audi 2.0T TSI 83mm 22mm Pin - 353850

VW/Audi 2.0T TSI | 83mm Bore | 9.6:1 | Forged 2618 | FSR | 22mm Pins | Skirt Coated | Set of 4

When you're building a Volkswagen or Audi 2.0T for more boost, a larger turbocharger, or a fresh performance short block, choosing the right pistons is one of the most important decisions you'll make. The JE Pistons FSR Forged Piston Kit, part number 353850, is designed for the 22mm wrist pin version of the 2.0T TSI engine, providing a stronger foundation for demanding turbocharged street and track applications.

These American-made 2618 forged aluminum pistons feature an 83.00mm bore, 9.6:1 nominal compression ratio, and -7.80cc dished crown. JE's Forged Side Relief construction helps reduce unnecessary reciprocating weight and piston friction, while accumulator grooves support ring stability under elevated cylinder pressure. Coated skirts and precision-honed pin bores address wear, operating noise, and assembly accuracy. With JE Pro Seal rings, steel wrist pins, and retaining locks included, the kit provides a complete piston package for enthusiasts looking to build their 2.0T properly rather than simply replace the original internals.

About the JE Pistons VW/Audi 2.0T TSI Forged Piston Kit

Built for Demanding Turbocharged Performance

Volkswagen and Audi 2.0T engines are popular platforms for turbocharger upgrades, but increasing cylinder pressure means the rotating assembly needs to be prepared for more demanding operating conditions.

JE's 2618 forged aluminum pistons provide strength and ductility suited to performance applications. They're a practical choice for builders repairing piston damage or assembling a stronger engine intended for increased boost and harder driving.

The 83.00mm bore is 0.50mm larger than the standard 82.50mm bore, making this set suitable for cylinders professionally machined to the required finished diameter. Its 9.6:1 nominal compression configuration provides a defined starting point for matching the pistons to the intended engine geometry.

Lightweight Forged Side Relief Construction

JE's proprietary FSR design reduces piston skirt width to minimize friction and unnecessary reciprocating mass. It also accommodates a shorter wrist pin, helping reduce overall piston assembly weight.

For a turbocharged engine that sees rapid changes in RPM, frequent acceleration, and demanding track use, reducing unnecessary reciprocating mass is a valuable part of an efficient rotating assembly.

Accumulator Grooves for Ring Stability

During high-load operation, combustion gases passing the top piston ring can increase pressure between the top and second rings.

JE machines an accumulator groove into this area to provide additional gas volume. The design helps reduce pressure buildup and ring flutter, supporting consistent top-ring sealing under demanding cylinder pressures.

Coated Skirts and Precision Pin Fit

JE's skirt coating is designed to reduce friction and wear against the cylinder walls while helping minimize operating noise.

The wrist pin bores are precision-honed for controlled pin clearance. JE identifies typical pin-to-bore clearances of 0.0003 to 0.0010 inches, with actual installation measurements determined during assembly.

The kit includes case-hardened 5115 steel wrist pins, JE Pro Seal rings, and retaining locks, giving engine builders the essential piston components for a properly prepared short block.

Whether you're rebuilding a damaged 2.0T engine or preparing for more ambitious turbocharged performance, JE Pistons 353850 offers forged construction, lightweight FSR design, and ring-control features in a complete four-cylinder piston kit.

Fitment & Installation Notes:

• Volkswagen / Audi 2.0T TSI: Designed for compatible engines using the 22mm wrist pin configuration and specified piston geometry.

• Engine Application: JE identifies the 2013-2015 2.0T TSI 22mm-pin configuration. Confirm the exact engine code and connecting rod design before ordering.

• Required Finished Bore: 83.00mm.

• Overbore: +0.50mm compared with the standard 82.50mm bore.

• Wrist Pin Diameter: 0.866 in., approximately 22mm.

• Connecting Rod Compatibility: Verify connecting rod small-end design and wrist pin fit. Some applications require aftermarket connecting rods with non-tapered 22mm small ends.

• Compression Ratio: Nominal 9.6:1 for the intended engine geometry. Actual compression depends on the cylinder head, gasket thickness, and deck clearance.

• Piston Configuration: -7.80cc dished crown with 1.165-inch compression height.

• Cylinder Machining: Measure the actual pistons and finish the cylinder bores to JE's required piston-to-wall clearance.

• Piston Ring Installation: Measure and adjust ring end gaps for the intended fuel, boost pressure, and operating conditions.

• Piston-to-Valve Clearance: Verify clearance during assembly, especially with modified cylinder heads or aftermarket camshafts.

• Engine Tuning: Fuel delivery, ignition calibration, boost control, and supporting components should match the completed engine build.

• Horsepower Rating: No fixed horsepower rating is specified for part 353850. Engine capability depends on the complete build, assembly, and tuning.

The JE Pistons 353850 kit combines American-made forged 2618 aluminum construction, an 83mm overbore, 22mm wrist pins, FSR forging, accumulator grooves, and coated skirts for performance-focused VW/Audi 2.0T TSI builds.
