JE Pistons FSR Forged Piston Kit for VW 2.0T TSI 82.5mm 9.6:1 - 353849

VW 2.0T TSI | 82.5mm Bore | 9.6:1 | -7.10cc Dish | Forged 2618 | FSR | 22mm Pins | Set of 4

Building a Volkswagen 2.0T TSI for more boost, a bigger turbocharger, or a stronger street and track engine? The JE Pistons FSR Forged Piston Kit, part number 353849, gives enthusiasts an upgraded foundation for a properly engineered turbocharged four-cylinder build. Whether you're replacing damaged factory pistons or refreshing the bottom end before future performance modifications, these American-made forged pistons deliver the material strength and purpose-built features needed for demanding engine operation.

This kit retains the 82.50mm standard bore and features a 9.6:1 nominal compression ratio, -7.10cc dished crown, and 22mm wrist pin configuration. JE's Forged Side Relief design helps minimize piston friction and unnecessary reciprocating weight, while accumulator grooves support ring stability under elevated cylinder pressure. Precision wrist pin fitting and coated piston skirts further address wear, assembly accuracy, and operating noise. With four forged pistons, JE Pro Seal piston rings, wrist pins, and retaining locks included, this package is well suited to a carefully planned performance rebuild.

About the JE Pistons VW 2.0T TSI FSR Piston Kit

Forged Strength for a Performance TSI Build

Volkswagen's 2.0T TSI is a popular platform for turbocharger upgrades and engine performance projects. As boost pressure and cylinder loads increase, the pistons need to be selected for the intended engine combination rather than treated as ordinary replacement parts.

JE manufactures these pistons from 2618 forged aluminum, a material chosen for strength and ductility under demanding combustion conditions. The kit is a performance-focused option for enthusiasts rebuilding a damaged engine or putting together a stronger short block while retaining the standard 82.50mm bore.

The 9.6:1 nominal compression configuration provides a defined starting point for matching the pistons to the intended cylinder head, connecting rods, crankshaft, and head gasket arrangement.

Lightweight Forged Side Relief Construction

JE's proprietary Forged Side Relief design uses a narrower piston skirt to reduce contact area and friction against the cylinder walls. It also accommodates shorter wrist pins, helping reduce unnecessary reciprocating weight.

For engines seeing repeated acceleration, higher boost, or demanding track operation, reducing piston friction and excess mass is a useful part of the overall engine design.

Accumulator Grooves for Ring Stability

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

JE's accumulator groove creates additional volume for those gases, helping reduce pressure buildup and limit ring flutter. This supports more consistent top-ring sealing under elevated cylinder pressure.

Coated Skirts and Precision Wrist Pin Fit

JE's skirt coating is designed to help reduce friction, cylinder wall wear, and operating noise. These are useful characteristics in a forged-piston engine that may spend as much time on the street as it does under heavy boost.

The wrist pin bores are precision-honed to achieve controlled clearance between the pistons and pins. JE identifies typical pin-to-bore clearances of 0.0003 to 0.0010 inches, with final dimensions established during engine assembly.

With JE Pro Seal rings, 5115 steel wrist pins, and retaining locks included, part 353849 provides the essential piston components for a properly prepared Volkswagen 2.0T TSI short block.

Fitment & Installation Notes:

• Volkswagen / Audi 2.0T TSI: Intended for compatible 22mm wrist pin engine configurations using the specified piston geometry.

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

• Required Finished Bore: 82.50mm.

• Bore Configuration: Standard bore, not a +0.50mm oversize piston.

• Wrist Pin Diameter: 0.866 in. (22mm nominal).

• Connecting Rod Compatibility: Verify the rod small-end design and wrist pin fit. Do not substitute this kit for a 23mm-pin piston application.

• Compression Ratio: Nominal 9.6:1 for the intended engine geometry. Final compression depends on combustion chamber volume, head gasket thickness, and piston deck clearance.

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

• Oil Squirter Clearance: Confirm piston and oil squirter clearance during assembly. The JE 22mm-pin FSR application catalog identifies oil squirter removal or suitable spacing as a potential requirement.

• Cylinder Preparation: Measure the actual pistons and finish the bores to JE's specified piston-to-wall clearance.

• Piston Ring Installation: Check and set ring end gaps according to JE's recommendations for the intended boost, fuel, and operating conditions.

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

• Engine Calibration: Fuel delivery, ignition timing, boost control, and supporting engine components must match the completed build.

• Horsepower Rating: No specific horsepower limit is established for part 353849. Engine capability depends on the complete rotating assembly, machining, supporting components, and tuning.

For enthusiasts rebuilding or upgrading a Volkswagen or Audi 2.0T TSI, the JE Pistons 353849 kit combines American-made forged 2618 aluminum construction, lightweight FSR design, accumulator grooves, and coated skirts in a complete four-cylinder performance piston package.
