UPGRADE TO THE TOUGHEST JE PISTONS FOR 1.8T 20V
This is a complete custom set of 83mm 9.0:1 compression ratio JE forged FSR 2.0L stroker pistons designed to IE race spec for all 06A 1.8T 20V VW/Audi engines. This is the piston set used in all high horsepower IE race engine builds. Engineered to withstand extreme race punishment, JE's trademarked coating Tuff Skirt ® and JE's own thermal barrier crown coating is utilized. This piston set features oil ring rail support allowing the piston rings to be moved further down on the piston. Furthermore, upgraded lateral gas ports also come standard to build up pressure behind the compression ring and seal it against the cylinder wall. The overall strength is completed with a set of JE upgraded tool steel wrist pins. The added displacement by increasing the bore and stroke of your engine block yields more power and torque on the same boost pressure, less chance of detonation at a given power level (Lower peak cylinder pressures), faster spool, and increases out of boost power levels.

JE's state of the art FSR forgings reduce mass and wear caused by friction without sacrificing strength. This is accomplished by using an asymmetrical skirt design instead of the traditional full-round skirt, also this reduces weight significantly. Designed specifically for boosted applications, FSR forgings utilize a larger, stronger skirt on the side of the piston which receives all the side loading during the high-pressure combustion process. The opposite skirt is smaller for lightweight. FSR pistons still use a full-width wrist pin and optimal large, wide pin bosses to carry the load of a turbocharged engine without wearing or ovaling out the pin bosses. In order to combat in cylinder noise commonly found in lightweight pistons, these feature an offset pin and keep very quiet in the bore. FSR pistons receive strict quality control and 23 point post-production inspection to ensure exact finish and tolerances in critical areas making the lightest, truly heavy duty piston on the market.
JE FSR design requires oil squirters to be modified or spaced out for clearance on some 1.8T blocks.
- Stroker pistons are not recommended for early 058 1.8T engine blocks
