All components are BRAND NEW and there is NEVER a core charge required. SOLD COMPLETE, TIMED & READY TO INSTALL Every IAG 600 FA20 Long Block is sold complete with all new timing components pre-installed, making the installation process straightforward and minimizing timing-related risks during assembly. This is especially helpful on FA20 engines, which have a more complex timing system than many Subaru platforms. Most installations can be completed in a day. BUILT WITH 100% NEW COMPONENTS The IAG 600 long block is built to support up to 600 BHP applications. The FA20F (DIT) short block begins with new Subaru FA20 engine case halves modified for improved oiling, bored and honed to 86.1mm using precision in-house equipment, and assembled with a new Subaru FA20 WRX crankshaft matched to high-performance ACL or King race main bearings. Upgraded IAG-Spec H-Beam connecting rods with ARP2000 rod bolts and forged JE FSR 86.1mm pistons complete the internals for enhanced strength and performance. FORGED RODS & PISTONS To overcome the known weaknesses of OEM FA20 connecting rods at higher torque levels, the IAG 600 features IAG-Spec H-Beam rods and ARP hardware. This upgrade provides greater reliability under increased cylinder pressures. Each short block also includes high-strength JE FSR 2618-alloy pistons with an asymmetrical skirt design for reduced weight and improved combustion characteristics. IAG 600 FA20F (DIT) CYLINDER HEAD PACKAGE The 600 FA20F head package uses brand new AW20 WRX OEM head castings. These are machined with multi-angle valve jobs, deck resurfacing, and ultrasonic cleaning before reassembly. Performance components include Kelford dual cylindrical valve springs with titanium retainers and new GSC Viton valve stem seals. The head assembly also incorporates Kelford 264-EZ camshafts for a broader power band and improved driveability.
