Along with these specially designed stroker pistons, the increased displacement to 2.1 liters is accomplished by using a larger 95.5mm stroke crankshaft and 144X20 connecting rod. This stroker combination results in a 2067CC displacement that yields more horsepower and torque on the same boost pressure, less chance of detonation due to lower peak cylinder pressures, faster spool, and produces more power on low octane fuel. JE stroker piston sets for the for VW/Audi 1.8T 20V engine are offered in 8.5:1 or 9.5:1 compression ratios.
Lower compression pistons (8.5:1) will allow higher boost levels on lower octane ratings with less chance of knock and cylinder detonation than higher compression ratio pistons. Lower compression will sacrifice out of boost power, spool time, and power/torque per pound of boost. Choose your compression ratio accordingly. For most engine builds we recommend using a higher compression ratio piston (9.5:1). Speak with your engine tuner about the fuel and boost pressures you will be using to determine the best compression for your engine.
To reach the increased 2067CC displacement and 95.5mm stroke on a 1.8T block, stroker pistons require to be 83mm (+2mm overbore). Overbore pistons require additional machine work including a cylinder bore and hone. This work must be performed by a machine shop.
Not only does overboring allow the increased displacement, but this additional work also ensures a proper piston to wall clearance and in most cases results in stronger compression, longer piston life, increased ring life, and quieter piston operation. JE Tuff Skirt coating upgrade.JE's race-bred Tuff Skirt coating is self-lubricating and provides improved anti-friction and reduced wear. This coating is applied to the piston skirt designed to increase piston life and withstand many different types of endurance racing. Coating upgrades are non-stock and manufactured by order, all coatings have a 4-6 week lead time.
JE thermal barrier crown coating upgrade The thermal barrier crown coating is applied to the piston dome, designed to reflect heat into the for combustion chamber. This increases exhaust gas velocity, greatly improves scavenging potential, and extends piston life by decreasing the rate of thermal transfer. JE 180 "Tool Steel" wrist pin upgrade JE 180 Tool Steel wrist pins are through-hardened 52100 high-carbon bearing steel for extreme 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 dimensional measurements and roundness.Recommended upgrade for all engines exceeding 125HP per cylinder. JE 210 "Drag Race" wrist pin upgrade For drag race use only!
Manufactured from the same through-hardened 52100 high-carbon bearing steel as the optional 180 tool steel wrist pins, the 210 Tool Steel pin offers the ultimate in JE wrist pin strength for the most extreme boosted, nitrous, and high torque applications. With strength comes weight, due to the increased wall thickness on JE 210 drag race wrist pins we only recommend this upgrade on non-street drag race only applications. Running this pin option on street driven vehicles will likely result in decreased engine life. When selecting your wrist pin wall thickness, keep projected cylinder pressure, endurance, boost levels, torque onset, and weight requirements in mind.Don't see what you're looking for? If the options for compression ratio or bore sizing does not meet your build requirements, an IE customer service associate can help you custom order a JE piston to your specs. Custom pistons include a price surcharge and are made to order, expect a 4-8 week lead time. Works with all internal water pump 06A engine blocks only, will not fit early external / drive shaft 058 engine blocks. The item "8.51 CR JE-PVA-4" is in sale since Tuesday, October 1, 2019.
