| Manufacturer's Description: Description: The IAG Performance Hand-Built 800 Subaru FA20F (DIT) is a great choice for those looking to get more out of their modified WRX. Each 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. Every IAG 800 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. The IAG 800 Long Block Package is ideal for clients looking for an engine to support up to 800 BHP applications. The IAG 800 FA20F (DIT) long block features our highly popular IAG 800 FA20F (DIT) WRX Short Block. The IAG 800 short block starts with new Subaru FA 2.0L engine case halves that are machined for improved oiling. Then IAG machines the case halves assembled together in our Haas VF-4SS CNC mill to accept the IAG Closed Deck Inserts that transform the block into a solid deck. The unique inserts feature small passages that allow needed coolant flow to the deck surface. The case halves are then CNC machined with O-ring receiver grooves around the bore surface as well as drilled and tapped to accept 1/2" head studs that greatly reduce head gasket failure during high cylinder pressure scenarios. Next, the short block is Deck Plate bored and honed that to 86.1mm on our in-house Sunnen SV-30 cylinder hone. IAG's in-house honing process is able to set piston to wall clearances tighter for a quieter running engine. The short block is measured and assembled using a new 2020 Subaru 2.0L WRX crankshaft that is matched to ACL or King main bearings. IAG-Spec H-Beam 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 86.1mm forged pistons are installed, along with an OEM oil plug finishing off the short block. 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 800 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. Each Stage 2 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 .210" wall 9310 tool steel wrist pins with Tru Arc locks. Our unique closed deck system significantly increases the strength of the OEM case halves. This process supports the cylinder walls at the top of the case in order to prevent flexing and possible cracking where the case bolt reliefs are cut into the back of the cylinder wall. During the installation process we machine the assembled case halves in our Haas VF-4SS CNC mill to accept the IAG Closed Deck inserts. Once the case has been machined we heat it in an oven while freezing the specially machined inserts with liquid nitrogen. The inserts are then pressed into place and then machined to a mirror finish. To ensure proper head gasket sealing for high boost an o-ring groove is added to the deck and a copper wire is installed. The unique inserts feature small passages that allow needed coolant flow to the deck surface. This means that the closed deck system does not affect the block's cooling ability and will not cause overheating, even in daily drivers.
