By adding structural support around the tops of the cylinder walls, the design limits cylinder wall movement and reduces the potential for cracking in high-stress areas like the case bolt reliefs. The assembled case halves are machined in our Haas VF-4SS CNC mill to accept IAG Closed Deck inserts, then the block is heated while the inserts are cryogenically cooled so they can be pressed into place for a secure mechanical fit. Once installed, the deck surface is machined to a smooth, mirror finish. Each insert is designed with built-in coolant passages so proper flow to the deck surface is maintained, meaning you get the added strength of a closed deck without sacrificing cooling performance.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cimg alt=\"IAG FA20F 1000 Series Closed Deck Short Block Parts\" loading=\"lazy\" src=\"https:\/\/i.shgcdn.com\/42ea0511-7a81-4121-a254-55d7e27c68a3\/-\/format\/auto\/-\/quality\/best\/\" style=\"display: block; margin: 0 auto;\"\u003e\u003c\/p\u003e\n\u003ch2 style=\"text-align: center;\"\u003eBUILT WITH 100% NEW COMPONENTS\u003c\/h2\u003e\n\u003cdiv class=\"product-text\"\u003e\n\u003cp\u003eThe IAG 1000 FA20 DIT Subaru Closed Deck Short Block for the 2015–2021 WRX begins with brand-new Subaru FA20F engine case halves that are precision-machined in our Haas VF-4SS CNC mill to accept IAG Closed Deck inserts, converting the factory open deck into a much stronger closed deck foundation built to handle serious cylinder pressure. Once the inserts are installed, deck plates are bolted on, and the block is bored and honed to 86.25mm using our Sunnen cylinder hone, allowing us to dial in exact piston-to-wall clearances for proper ring seal, quiet operation, and reduced oil consumption. While it’s on the mill, we machine a groove at the top of each cylinder for the Fire-Lock head gasket system and drill the head bolt holes to accept 14mm head studs. From there, the case halves are assembled with a brand-new Subaru FA20 DIT crankshaft, IAG-Spec H-Beam forged connecting rods with ARP 625+ rod bolts, and ACL or King Race rod and main bearings. Finally, every short block is balanced, blueprinted, and sealed with new OEM main and case bolts and factory sealant, delivering a rock-solid foundation built to handle up to 1000 BHP.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cimg alt=\"IAG FA20F Closed Deck Fire-Lock System\" loading=\"lazy\" src=\"https:\/\/i.shgcdn.com\/b4d709a6-923f-4123-9754-45defd90ee96\/-\/format\/auto\/-\/quality\/best\/\" style=\"display: block; margin: 0 auto;\"\u003e\u003c\/p\u003e\n\u003ch2 style=\"text-align: center;\"\u003eIAG FIRE-LOCK SYSTEM\u003c\/h2\u003e\n\u003cdiv class=\"product-text\"\u003e\n\u003cp\u003eThe IAG 1000 FA20F Subaru Closed Deck Short Block features our proprietary “Fire-Lock” Head Gasket System. This system has been proven in our record-setting race cars to be the strongest Subaru head gasket system ever produced. To achieve these results, our engineers separated combustion sealing from the oil and coolant sealing functions of a traditional head gasket. Each cylinder is precision-machined with a counterbore step at the top to accept the Fire-Lock ring that mechanically locks into place and creates an extremely secure combustion seal. The independent gasket bodies handle sealing the oil and coolant passages, keeping fluids out of the combustion chamber where they don’t belong. The entire assembly is secured using 14mm head studs for maximum clamping force (Fire-Lock Gaskets and 14mm Head Studs sold separately).\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cimg alt=\"IAG-Spec FA20F JE Forged Pistons\" loading=\"lazy\" src=\"https:\/\/i.shgcdn.com\/1da7207e-c072-4886-b49c-c9f42d051204\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\" style=\"display: block; margin: 0 auto;\"\u003e\u003c\/p\u003e\n\u003ch2 style=\"text-align: center;\"\u003ePISTONS DESIGNED WITH POWER IN MIND\u003c\/h2\u003e\n\u003cdiv class=\"product-text\"\u003e\n\u003cp\u003eThe pistons in the IAG 1000 FA20 DIT Subaru Closed Deck Short Block are built to handle the demands of serious performance use.

This solution is loosely derived from diesel technology, where a counterbore step is machined around each cylinder bore, allowing specially sized fire rings to drop into the machined area and head gasket bores. The shims are designed to create a compression seal once the heads are installed and torqued into place. IAG fire rings are manufactured to a very strict tolerance from a proprietary alloy and are then put through a heat treatment process. The gaskets are manufactured from an asbestos-free composite raw material and feature a silicone-based beading applied to critical areas to improve sealing around all water and oil passages. The combination of the alloy compression shims and gaskets assures maximum sealing for a Subaru FA20 turbocharged engine.\u003c\/p\u003e\n\u003cp\u003eThe IAG Fire-Lock gaskets require machine work for installation and are recommended for use with 14mm head stud hardware.\u003c\/p\u003e\n\u003cp\u003eThe gaskets are sold in pairs with four Fire-Lock rings.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch2 style=\"text-align: center;\"\u003eOIL PICKUP\u003c\/h2\u003e\n\u003cdiv class=\"product-text\"\u003e\n\u003cp\u003eOil pickups are a critical failure point in the FA20F engines, especially when pushing your Subaru to its limits. The factory pickup can lead to severe engine damage or catastrophic failure due to the screen dislodging under high oil pressure, allowing debris and even fragments of the screen itself to enter the engine. Subaru’s design is also notorious for restricting oil flow, creating the potential for oil starvation. The IAG Performance Oil Pickup for the 2015-2021 FA20F WRX is designed to solve these issues. With an enhanced design that improves oil flow and durability, it offers a dependable solution to the common problems with OEM oil pickups.
