COMPRESSION RATIO:

JE piston sets for the VW/Audi 1.8T 20V engine are offered in 8.5:1 or 9.25:1 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 (9.25:1). Speak with your engine tuner about the fuel and boost pressures you will be using to determine the best compression for your engine.

BORE SIZE:

JE offers your choice of bore size to suit your build. You have the option of stock bore sizing (81mm) or +.5m to +2mm oversized bores. Overbore pistons require additional machine work including a cylinder bore and hone. This work must be performed by a machine shop. For most performance engine builds, we recommend overboring the engine block when installing aftermarket pistons. This additional work 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.
