I"ve got 5 sets of CP pistons that are a drop in for ej257 blocks. They are an exact copy of the stockers, only forged.

Pistons with pins, rings $600 shipped
Pistons with pins, no rings $500 shipped

These pistons are designed to utilise the stock Subaru piston rings and pin clips.

Weight is 398 grams

Piston to bore clearance is .0035"


These pistons will make some slight engine noise on startup until engine is warm. Then noise should suppress nicely.
