The Long Blocks feature a combination of our proven IAG Performance Short Block and Cylinder Head packages, along with other race-proven components to complete the assembly. When paired with our Long Block Installation Packages, you have a true plug-and-play solution to get you back on the road, FAST! All components included 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 and ready to install. Since their introduction to the WRX lineup in 2015, the FA20F has proven to be one of the more difficult Subaru engines to work on, especially for those who are inexperienced with the platform. The timing system on these engines is complicated. One wrong move can leave you needing a new set of valves. In building the IAG Long Block line we set out to make installation as easy as possible. To that end, we have decided to only offer the FA20 long blocks with all new timing components pre-installed. This means all your mechanic needs to do is swap over the manifolds, sensors, injectors, and external accessories to get you back on the road ASAP. Most installations can be completed in a day.
BUILT WITH 100% NEW COMPONENTS
IAG 600 FA20F (DIT) CYLINDER HEAD PACKAGE
The 600 FA20F (DIT) Cylinder Head Package starts with brand new AW20 WRX OEM head castings directly from Subaru of America. The heads are then fixtured in our Newen Contour Valve Guide and Seat Machine to cut all intake and exhaust seats with a multi-angle valve job that suits the flow characteristics of new GSC valves. The head decks are then resurfaced using our TS-3000 BlockMate, which cuts the aluminum to a smooth, even finish. To remove debris and oils from the machining process, the heads are ultrasonically cleaned. Finally, the lower portion of the heads are reassembled using Kelford Dual Cylindrical Valve Springs and Retainers along with new GSC viton valve stem seals. The heads are then attached to the short block using an OEM Subaru cylinder head gasket and secured with 11mm ARP 2000 head studs.
The IAG 600 FA20 WRX Head Package also features Kelford's new 264-EZ Camshafts, which are proven to add a significant bump in power across the rev range without sacrificing driveability. The cams are installed in the upper cam tower assembly and attached to the lower portion of the head casting. Valve lash is carefully measured and set at this time using new, OEM shims for proper clearance. New OEM valve covers are added for a complete valve cover-to-valve cover assembled long block. Once assembled, we add new OEM timing components and a Subaru FA20 timing chain cover with built-in oil pump.
