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, Manley 86.1mm 10.0:1 Compression Ratio Platinum Series Forged Pistons are spec'd and installed finishing off the short block.
