GReddy Superior Spec. 2.1L FA20 / 4U-GSE Stroker Kit


Engine strengthening is crucial for safety and reliability of FR-S and BRZ over the 350hp mark.  GReddy engineers have drawn from our FR-S race experience to assemble a complete stroker kit for the FA20/4U-GSE boxer engine, using only superior components.  



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.  And at the heart of the 2.1L kit is our dynamic balanced, E4340 Cr-Ni-Mo alloy billet steel stroker crankshaft.
