These 1ZZ pistons from Wiseco are forged from 2618 aluminum and machined to exceptional tolerances. They are designed for tighter piston to cylinder clearances than other aftermarket pistons to minimize piston slap and cylinder bore wear. These are excellent pistons for street or race.
Every piston set includes 4 pistons, premium quality piston rings, precision chromoly wrist pins and retainer rings.
0.5mm overbore requires that your block be bored and honed. Sleeves not required.
8.8:1 Compression Ratio for turbo and supercharged applications.
