A "DROP-IN" SOLUTION

The IAG Performance Hand-Built 600 Subaru FA20F (DIT) Long Block Package is a complete, valve cover to valve cover, timed, crate engine. These engines offer significant ease of installation for customers seeking a complete "drop-in" engine package for their 2015+ Subaru WRX. 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.

IAG 600 FA20F (DIT) SHORT BLOCK

IAG 600 FA20F DIT Short Block for 2015-21 WRX

The IAG 600 Long Block Package is ideal for clients looking for an engine to support up to 600 BHP applications. The IAG 600 FA20F (DIT) long block features our highly popular IAG 600 FA20F (DIT) WRX Short Block.

The IAG 600 FA20F Short Block starts with a new Subaru FA 2.0L engine case half set. Our engine builders modify the oil passages inside the case for improved oiling. Once the oiling modifications are completed the case is bored and honed to 86.1mm on our in-house Sunnen SV-30 cylinder hone. This computer controlled hone is the most advanced automotive cylinder hone available. Through our specialized in-house honing process we are able to set piston to wall clearances tighter, for a quieter running engine. The short block is measured and assembled using a new 2015+ Subaru 2.0L FA20 WRX crankshaft which is matched to IAG Spec main bearings. IAG Spec H-Beam connecting rods with ARP2000 rod bolts are utilized, along with King or ACL rod bearings. The case halves are sealed with new OEM case bolts and sealant. Finally, IAG-Spec JE FSR 86.1mm forged pistons are carefully measured and installed, along with an OEM oil plug to finish off the short block.

FORGED RODS
TO SUPPORT MORE TORQUE

It's no secret that the OEM connecting rods are the weak link when it comes to the FA20F engines. Any increases in low end torque can stress the OEM rods to the point of breaking. When a rod breaks it causes catastrophic damage inside the engine, sometimes even leaving big holes in the engine case. With this in mind, all of our FA20 short blocks feature upgraded rods. The IAG 600 FA20 DIT Long Block features IAG Spec H Beam connecting rods with ARP 2000 hardware, which are a significant upgrade from the OEM components. You can feel confident when increasing your horsepower and torque that the rods are designed to handle the stress.

IAG 600 FA20F DIT WRX JE Pistons

FORGED PISTONS
DESIGNED FOR BOOST

Each IAG 600 FA20F DIT WRX Short Block features IAG Spec JE FSR 86.1mm Forged Pistons. These 2618 T6 Alloy high-strength pistons have been specifically designed to support increased cylinder pressures which come with more boost. FSR forgings reduce mass and wear caused by friction without sacrificing strength. This is accomplished by using an asymmetrical skirt design instead of the traditional full-round skirt, also this reduces weight significantly. Featuring smooth flowing radii on the domes and dishes, the design promotes excellent flame travel. The pistons are secured to the rods with .905 x 2.250" x .150" wall 9310 tool steel wrist pins with Tru Arc locks.


IAG 600 FA20F (DIT) CYLINDER HEAD PACKAGE

IAG 600 FA20F DIT WRX

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.
