WHAT IS A 3.0L STROKER PISTON?
Stroker pistons feature a larger bore, larger oil squirter notches, modified piston dish, and properly place wrist pins allowing you to up the displacement by increasing the stroke and bore of the engine. Along with these specialty designed stroker pistons, the increased displacement to 3.0 liters is accomplished by using a larger 92.8mm stroke crankshaft and 154X21 connecting rod. This stroker kit results in a 3.0L 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.
TECHNICAL SPECIFICATIONS
- Bore: 82mm or 83mm
- Stroke: 92.8mm
- Rod size: 154X21
- Compression Ratio: 8.5:1
COMPRESSION RATIO
JE stroker piston sets for the Audi 2.7T 30V engine are offered in an 8.5:1 compression ratio. This compression will allow higher boost levels on lower octane ratings with less chance of knock and cylinder detonation than higher compression ratio pistons. This compression ratio is a perfect match for engine builds running high boost, high torque, or race fuels/nitrous requiring this type of forged piston.
INCREASED BORE SIZE
Requires machine work! To reach the increased displacement and stroke on a 2.7T block, stroker pistons require to be 82mm 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. For engines with cylinder damage past 82mm bores, an 83mm bore option is also available.
