Lower compression pistons (8.5:1) are typically used on boosted engines, resulting in 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 naturally aspirated engine builds we recommend using a higher compression ratio piston (11.5:1). Speak with your engine tuner about the fuel and boost pressure used to determine the best compression for your engine.\u003cbr\u003e\u003cstrong\u003e\u003cbr\u003e \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBore Size\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eJE offers your choice of bore size to suit your build. You have the option of stock (84mm) bore sizing, +.5mm overbore sizing (84.5mm) or +1mm (85mm) 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.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMeasurements And Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"text-decoration: underline;\"\u003eStock bore size:\u003c\/span\u003e\u003cbr\u003eBore: 81mm\u003cbr\u003eStroke: 86.4mm\u003cbr\u003eRod size: 144X20\u003cbr\u003eDome CC (8.5:1): -8.1\u003cbr\u003eDome CC (9.25:1): -2.7\u003cbr\u003eWeight (8.5:1): 296 grams\u003cbr\u003eWeight (9.25:1): 299 grams\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"text-decoration: underline;\"\u003e+.5mm bore size:\u003c\/span\u003e\u003cbr\u003eBore: 81.5mm\u003cbr\u003eStroke: 86.4mm\u003cbr\u003eRod size: 144X20\u003cbr\u003eDome CC (8.5:1): -9.3\u003cbr\u003eDome CC (9.25:1): -3.6\u003cbr\u003eWeight (8.5:1): 310 grams\u003cbr\u003eWeight (9.25:1): 303 grams\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"text-decoration: underline;\"\u003e+1mm bore size:\u003c\/span\u003e\u003cbr\u003eBore: 82mm\u003cbr\u003eStroke: 86.4mm\u003cbr\u003eRod size: 144X20\u003cbr\u003eDome CC (8.5:1): -9.3\u003cbr\u003eDome CC (9.25:1): -3.6\u003cbr\u003eWeight (8.5:1): 310 grams\u003cbr\u003eWeight (9.25:1): 308 grams\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"text-decoration: underline;\"\u003e+2mm bore size:\u003c\/span\u003e\u003cbr\u003eBore: 83mm\u003cbr\u003eStroke: 86.4mm\u003cbr\u003eRod size: 144X20\u003cbr\u003eDome CC (9.25:1): -6.5\u003cbr\u003eWeight (8.5:1): 310 grams\u003cbr\u003eWeight (9.25:1): 312 grams\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eManufacturing Details\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"text-decoration: underline;\"\u003eForged from 2618 T6 aluminum\u003c\/span\u003e\u003cbr\u003eEngineered for extreme operating environments found in professional motorsport competition, JE manufactures this light yet strong piston from high tensile strength 2618 T6 aluminum.
