JE Pistons FSR Forged Piston Kit for VW 2.0T TSI 82.5mm 23mm Pin - 353859

JE Pistons | VW 2.0T TSI | 82.5mm Forged Pistons | 9.6:1 Compression | FSR | 23mm Pin | Set of 4

Building a stronger Volkswagen 2.0T TSI for increased boost, spirited street driving, or weekend track use? The JE Pistons Forged Piston Kit, part number 353859, gives your turbocharged four-cylinder engine a performance-focused foundation without requiring a different bore size from the standard 82.5mm configuration. Whether you're repairing a damaged bottom end or planning a more ambitious turbo setup, these American-made 2618 forged aluminum pistons offer the strength and ductility needed for demanding engine builds.

Designed around the VW 2.0T TSI 23mm wrist pin configuration, this set features a 9.6:1 nominal compression ratio, -7.10cc dished crown, and JE's lightweight Forged Side Relief (FSR) design. Accumulator grooves help improve ring control under high cylinder pressure, while precision pin fitting and coated piston skirts address friction, wear, and operating noise. With JE Pro Seal rings, wrist pins, and retaining locks included, this is a complete four-piston package for enthusiasts who want to build their engine properly the first time.

About the JE Pistons 2.0T TSI Forged Piston Kit

A Stronger Foundation for Turbocharged Performance

Volkswagen's 2.0T TSI is a popular engine for performance builds, but additional boost and cylinder pressure place greater demands on the rotating assembly. Choosing the right forged pistons is an important part of preparing the engine for more aggressive use.

JE's 2618 forged aluminum construction offers strength and ductility suited to elevated combustion pressures. These pistons provide a performance-oriented alternative to factory-style internals for builders who want to upgrade the bottom end while retaining the specified 82.5mm bore and 9.6:1 compression configuration.

The 23mm wrist pin design is especially important when selecting compatible connecting rods. This set is intended for the later 23mm-pin TSI engine configuration rather than earlier variants using different wrist pin diameters.

Lightweight Forged Side Relief Design

JE's proprietary FSR forging reduces piston skirt width to help minimize friction and unnecessary reciprocating mass. The design also accommodates a shorter wrist pin while maintaining a structure suitable for demanding performance applications.

Reducing friction and reciprocating weight can be valuable in an engine that sees frequent acceleration, sustained high RPM, and increased turbocharger output.

Accumulator Grooves for Ring Control

As cylinder pressure increases, combustion gases trapped between the top and second piston rings can affect ring stability.

JE's accumulator groove adds volume between the rings, helping reduce pressure buildup and limit ring flutter. This supports more consistent top-ring sealing during demanding operating conditions.

Skirt Coating and Precision Pin Fit

JE's skirt coating is designed to reduce friction and wear between the piston skirts and cylinder walls. It also helps reduce operating noise, which can be especially useful in a street-driven engine using 2618 forged pistons.

The precision-honed wrist pin bores provide controlled pin-to-piston clearance. JE identifies typical pin-fit clearances of 0.0003 to 0.0010 inches, with final measurements determined by the engine builder.

Together with the included JE Pro Seal rings and wrist pin hardware, these features make the 353859 kit a practical choice for a properly engineered turbocharged Volkswagen engine build.

Fitment & Installation Notes:

• Volkswagen 2.0T TSI: Designed for the 23mm wrist pin engine configuration.

• Engine Application Reference: 2013+ European / 2015+ USA 2.0T TSI configurations identified by JE. Verify the specific engine code before ordering.

• Bore Requirement: 82.50mm finished cylinder bore.

• Wrist Pin Compatibility: Requires connecting rods compatible with the supplied 23mm wrist pins.

• Pin Configuration: Not interchangeable with 21mm or 22mm wrist pin applications without compatible engine components.

• Compression Ratio: Nominal 9.6:1 for the specified engine geometry. Final assembled compression ratio depends on combustion chamber volume, head gasket dimensions, and deck clearance.

• Piston Configuration: -7.10cc dished crown with 1.165-inch compression height.

• Engine Stroke: Designed around the listed 3.654-inch stroke.

• Cylinder Machining: Measure cylinder bores and establish the correct piston-to-wall clearance using JE's specifications and the actual piston measurements.

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

• Valve Clearance: Confirm piston-to-valve clearance during assembly, particularly with aftermarket camshafts or modified cylinder heads.

• Connecting Rods: Verify rod length, small-end diameter, and wrist pin compatibility before assembly.

• Engine Calibration: Proper fuel delivery, ignition timing, and boost control are essential for a reliable modified turbocharged engine.

• Horsepower Rating: No specific horsepower limit is published for part 353859. Engine capability depends on the complete rotating assembly, cylinder preparation, supporting components, and tuning.

Whether you're rebuilding a tired TSI engine or assembling a stronger bottom end for a bigger turbocharger, the JE Pistons 353859 kit brings forged 2618 construction, FSR design, improved ring-control features, and skirt coating to a complete four-cylinder performance piston package.
