IAG Performance : 600 FA20 Low Compression 10.5:1 Short Block - Subaru BRZ/Toyota 86

POWER RATING

The IAG 600 Long Block has a power output rating of 600BHP.

DESIGNED FOR STRENGTH

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. The IAG 600 short block features IAG Spec H-Beam forged connecting rods. The upgraded connecting rods and race bearings are able to support additional engine load produced by aftermarket turbochargers or increased boost which the OEM rods and pistons found in the stock short blocks cannot support reliably.

BUILT WITH 100% NEW COMPONENTS

Each IAG 600 Short Block starts with brand new FA20 BRZ/FT86 2.0L, 86mm stock bore engine case halves as standard. The case haves are carefullly bored and honed to 86.1mm then measured and assembled using a new 2015+ Subaru 2.0L FA20 crankshaft, which is matched to ACL or King race main bearings. The IAG 600 Short Block features IAG Spec H-Beam Connecting Rods with ARP2000 rod bolts, along with ACL or King race rod bearings. The case halves are sealed with new OEM main case bolts and sealant. Finally, IAG Spec JE FSR 86.1mm Forged Pistons are carefully selected, measured, and installed to finish off the short block.

MODIFIED OIL PASSAGES FOR INCREASED OILING

Adequate oil flow is critical to performance and relibility. It's no secret that the OEM cases from Subaru leave something to be desired in the oiling department. Our machinists carefully inspect and modify the internal oil passages of each new OEM case used in the IAG 600 Short Block to ensure proper flow and reliability.

QUALITY GUARANTEED

We stand behind every hand-built engine we produce. IAG's Standard Long Block Workmanship Warranty covers your long block for 12 months or 12,000 miles.
