IAG 600 FA20 Subaru Short Block

The IAG 600 Short Block is designed for stock or modified FA20 Subaru BRZs that need a stronger short block to support increased cylinder pressures created by modifications, or aftermarket turbo kits. It features IAG Spec H-Beam forged connecting rods with ARP2000 rod bolts, ACL or King race rod bearings, and IAG Spec JE FSR 86.1mm Forged Pistons. Each short block starts with brand new FA20 BRZ/FT86 2.0L, 86mm stock bore engine case halves, which are bored and honed to 86.1mm. It is assembled using a new 2015+ Subaru 2.0L FA20 crankshaft matched to ACL or King race main bearings. The case halves are sealed with new OEM main case bolts and sealant.
