IAG Stage 2 FA20 Subaru Short Block for 2013-18 BRZ / FR-S (10.0:1 Compression Ratio)
The IAG Stage 2 short block starts with new Subaru FA 2.0L BRZ engine case halves that are machined for improved oiling. Then the case is bored and honed to 86.1mm on our in-house Sunnen SV-30 the most advanced automotive cylinder hone available. IAG‘s in-house honing process is able to set piston to wall clearances tighter for a quieter running engine. The short block is measured and assembled using a new FA20 WRX / BRZ Subaru crankshaft that is matched to King main bearings. Brian Crower H-Beam rods with ARP2000 rod bolts are utilized along with King or ACL rod bearings. The case halves are sealed with new OEM case bolts and sealant. Finally, lower compression IAG-Spec 86.1mm 10.0:1 compression ratio forged pistons are spec'd and installed along with an OEM oil plug finishing off the short block. The lower compression ratio is good for BRZ / FR-S forced induction conversion applications.
