Product Summary

This is a custom set of forged JE pistons for VW & Audi 1.8T 20V engines, made to your specifications. These pistons are made from JE's 2618 alloy with several options available for bore, stroke, compression ratio, and additional features. These pistons all come standard with 20MM wrist pins, which can be used with Integrated Engineering 144x20MM connecting rods.

CUSTOM PISTON OPTIONS

Compression ratio
Lower compression ratios are recommended for higher boost applications. When using a middle sized turbo on a street car, compression ratios around 9.0:1 are recommended. Anything above 9.5:1 is for naturally aspirated use only.

Cylinder bore
Factory bore on the 1.8T engine is 81MM. Increasing the bore will increase displacement, thus increasing power. Boring the engine out is always recommended, especially for stroker engines. If you start with the maximum bore, you will not be able to remachine the block if any damage is caused to the cylinder walls.

Piston Stroke
The factory stroke of the 1.8T engines is 86.4MM. There is the option to use the 2.0T FSI crank, which is the 92.8MM stroke crank. That along with an 83MM bore will put the displacement to 2008cc. The other stroker option is the TDI crank which uses the 95.5MM crank, and with an 83MM bore will increase displacement to 2067cc. You must use the correct crank for the stroke provided, or serious engine damage can occur.

Tool Steel Wrist Pins
The tool steel wrist pin option is to upgrade from the standard mild steel pins, to JE's thick wall tool steel wrist pins. They are recommended for ~400+ WHP.

Piston coatings
There is two coating options that we offer with the JE- Thermal Barrier Crown, and Tuff Skirt. The Thermal Barrier crown coating is applied to the top of the piston, and is designed to keep heat out of the piston, and deflect it into the combustion chamber. This will increase exhaust gas velocity, as well as extend piston life. The Tuff Skirt coating is an anti-friction coating applied to the skirt of the piston. This coating will help reduce wear on skirts and cylinder walls.

Target HP
Please select an approximate target HP goal. We will be able to recommend any additional features, if needed.

IMPORTANT NOTES

  • All pistons include rings, wrist pins, and wire locks.
  • Pistons take 2-3 weeks for manufacturing, and another 1-2 weeks with coatings
  • All sales on custom pistons are final, no returns will be accepted
  • Please contact us before purchasing with any questions
