  • The IAG Stage 2 short block starts with new Subaru FA 2.0L 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 2015-20 Subaru 2.0L WRX 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, IAG-Spec 86.1mm forged pistons are spec’d and installed along with an OEM oil plug finishing off the short block.
