| IE Race Spec JE Forged Pistons (83MM / 9.5:1 CR / 92.8MM Stroke)
This is a complete custom set of 83mm 9.5:1 compression ratio JE forged FSR 2.0L stroker pistons designed to IE race spec for all belt-drive 2.0T FSI 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 ﾮ 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 over all strength is completed with a set of JE upgraded tool steel wrist pins. The added displacement by increasing the bore 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. These pistons require 20mm wrist pin connecting rods such as Integrated Engineering h beam 144X20 or Integrated Engineering Tuscan I beam 144X20 connecting rods. IE race spec JE FSR pistons are custom made to order, please allow up to 5 - 6 weeks for delivery. JE FSR Forged Pistons
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 high pressure combustion process. The opposite skirt is smaller for light weight. 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 recieve strict quality control and 23 point post production inspection to ensure exact finish and tolerances in critical areas making the lightest, truely heavy duty piston on the market. JE FSR design requires oil squirters to be modified or spaced out for clearance on some 2.0T blocks.

Tuff Skirt ﾮ
JE Pistons trademarked coating Tuff Skirt is a lubricating, anti-friction / anti-wear coating applied to the piston skirt designed to withstand many different types of endurance racing. Thermal Barrier Crown
The thermal barrier crown coating is applied to the piston dome and is designed to reflect heat into the combustion chamber. This increases exhaust gas velocity, greatly improves scavenging potential, and extends piston life by decreasing the rate of thermal transfer. JE Tool Steel Wrist Pins
JE Tool Steel Wrist Pins are through-hardened high-carbon bearing steel for forced induction or nitrous-fed racing applications and offer high-strength with low ductility. Employing the latest in technology, each pin is checked to ensure the highest quality and roundness |
