    Stage 2.5 FA20 Closed Deck Short Block (12.5:1 Compression Ratio) by IAG

    The IAG Stage 2.5 short block starts with new Subaru FA 2.0L BRZ engine case halves, IAG machines the case halves assembled together in our Haas VF-4SS CNC mill to accept the IAG CLOSED Deck Inserts that transform the block into a solid deck.

    The unique inserts feature small passages that allow needed coolant flow to the deck surface. Next, the short block is Deck Plate bored and honed that to 86.25mm 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 modified case halves are then 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, standard compression IAG-Spec 86.25mm 12.5:1 compression ratio forged pistons are spec'd and installed along with an OEM oil plug finishing off the short block.
