GReddy Superior Spec. 2.1L FA20 / 4U-GSE Engine Stroker Kit
Engine strengthening is crucial for safety and reliability of FR-S and BRZ over the 350hp mark.

The kit features 9.5:1, 86mm bore. 2618 T6 forged aluminum pistons with specially designed shape ideal for high boost applications. This is connected to extra strong H-beam 433OM steel alloy forged connecting rods with a factory style 18deg. split line.
