IAG Stage 3 FA20 DIT Short Block
The IAG Stage 3 short block starts with new Subaru FA 2.0L 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 2015-17 Subaru 2.0L WRX crankshaft that is matched to King main bearings. Manley I-Beam rods are utilized along with King rod bearings. The case halves are sealed with new OEM case bolts and sealant. Finally, Manley 86.1mm Platinum Series Forged Pistons are spec'd and installed finishing off the short block.
