Description Applications

IAG Stage 2 FA20 DIT Short Block

The IAG Stage 2 short block starts with new Subaru FA 2.0L BRZ engine case halves that are bored and honed to 86.1mm on our in-house Sunnen SV-10. 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 DIT Subaru crankshaft that is matched to King main bearings. Brian Crower H-Beam rods with ARP2000 rod bolts are utilized along with King rod bearings. The case halves are sealed with new OEM case bolts and sealant. Finally, lower compression Manley 86.1mm 10.0:1 Compression Ratio Platinum Series Forged Pistons are spec'd and installed finishing off the short block. The lower compression ratio is perfect for BRZ / FR-S forced induction conversion applications.
