**This is a REPLACEMENT set of stroker pistons which ONLY work with a MWR 1.9L or 2.0L 2ZZ stroker kit. Do not buy this piston set unless you already have a 1.9L or 2.0L stroker kit from MWR. We do not sell the stroker kits minus pistons.**
These 2ZZ pistons from Wiseco are forged from 2618 aluminum and machined to exceptional tolerances. They are designed for tight piston to cylinder clearances 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.
82.5mm (0.5mm overbore) requires the use of Darton Sleeves. MWR strongly recommends using 82.0mm pistons for a new sleeved engine build. This allows one more overbore to 82.5mm later if you wear out or damage your 82.0mm pistons.
