This ultimate \"weekend racer\" block is engineered to handle up to 1000 BHP and built to dominate in any setting. The IAG 1000 FA24 Short Block features +2mm IAG Spec H-Beam forged connecting rods, IAG-Spec JE Pistons with electroless nickel-plated coating and H13 tool steel wrist pins. The block is precision-machined to accommodate our venerable \"Fire-Lock\" head gasket system and IAG 14mm head studs (sold separately). Each IAG 1000 short block is hand assembled using ACL rod and main bearings. The versatile IAG 1000 is the perfect setup that excels on the street, the drag strip and on the track.\u003c\/p\u003e\u003c\/div\u003e\n\u003cimg alt=\"Subaru FA24 WRX Heat Treated Crank\" loading=\"lazy\" src=\"https:\/\/i.shgcdn.com\/ccaa31e2-019a-4365-b3c8-ef5303627015\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\" style=\"display:block;margin:0 auto;\"\u003e\n\u003ch2 style=\"text-align:center;\"\u003eBUILT WITH 100% NEW COMPONENTS\u003c\/h2\u003e\n\u003cdiv class=\"product-text\"\u003e\u003cp\u003eThe IAG 1000 FA24 Short Block starts with brand new Subaru 2.4L WRX engine case halves. Our machinists machine the assembled case halves in our Haas VF-4SS CNC mill to accept the IAG Closed Deck inserts, transforming the block into a solid deck. Next, a pair of deck plates are attached and the short block is bored and honed to 94.25mm in our in-house Sunnen cylinder hone. IAG's in-house honing process allows us to set custom piston to wall clearances to ensure quiet operation and reduced oil consumption. The Haas mill also cuts a groove at the top of each cylinder to accept the Fire-Lock head gasket rings and drills each head bolt hole for 14mm head studs. The modified case halves are then assembled using a new 2022+ Subaru 2.4L heat treated WRX crankshaft and IAG-Spec Tuff H-Beam connecting rods with ARP rod bolts. IAG Short blocks feature ACL rod and main bearings and are all balanced and blueprinted. Finally, the case halves are sealed with new OEM main\/case bolts and sealant.\u003c\/p\u003e\u003c\/div\u003e\n\u003cimg alt=\"IAG Fire-Lock Head Gaskets for FA24 WRX\" loading=\"lazy\" src=\"https:\/\/i.shgcdn.com\/26c67381-a1be-4b30-ae68-66948191bdee\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\" style=\"display:block;margin:0 auto;\"\u003e\n\u003ch2 style=\"text-align:center;\"\u003eNEVER WORRY ABOUT HEAD GASKET FAILURES\u003c\/h2\u003e\n\u003cdiv class=\"product-text\"\u003e\u003cp\u003eThe IAG 1000 FA24 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 the combustion chamber sealing from the fluid sealing aspects of the head gaskets. Our machinists carefully machine a lip at the top of each cylinder to accept the \"Fire-Lock\" ring. With the ring locked in place, it stands proud above the deck, providing a superior seal. The separate gasket bodies take care of sealing oil and coolant passages and keeping them out of the combustion chamber. 14mm Head studs hold the assembly together. (Fire-Lock Gaskets and 14mm Head Studs Sold Separately).\u003c\/p\u003e\u003c\/div\u003e\n\u003cimg alt=\"IAG FA24 WRX Closed Deck Conversion\" loading=\"lazy\" src=\"https:\/\/i.shgcdn.com\/c2dcf376-ac55-49c3-8779-87f006dbcb32\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\" style=\"display:block;margin:0 auto;\"\u003e\n\u003ch2 style=\"text-align:center;\"\u003eCLOSED DECK FOR EXTRA STRENGTH\u003c\/h2\u003e\n\u003cdiv class=\"product-text\"\u003e\u003cp\u003eOur 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. 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. \u003c\/p\u003e\u003c\/div\u003e\n\u003cimg alt=\"IAG-Spec JE FSR Pistons for 2022+ Subaru WRX\" loading=\"lazy\" src=\"https:\/\/i.shgcdn.com\/099ed62c-3c87-4c72-91ea-17cadda57ce4\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\" style=\"display:block;margin:0 auto;\"\u003e\n\u003ch2 style=\"text-align:center;\"\u003ePISTONS SPECIALLY DESIGNED WITH POWER IN MIND\u003c\/h2\u003e\n\u003cdiv class=\"product-text\"\u003e\u003cp\u003eThe pistons used in the IAG 1000 FA24 Short Blocks are specifically designed to support the rigors of racing.

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 assure maximum sealing for a Subaru FA24 turbocharged engine.*The IAG Fire-Lock gaskets require machine work for installation and are recommended for use with 14mm head stud hardware.*The gaskets are sold in pairs with four Fire-Lock rings.Features:\u003c\/p\u003e\n\u003cp\u003eInstall Notes:1. If a block or cylinder head was previously o-ringed the groove must be filled and resurfaced before using this type of gasket.2. These gaskets require IAG ARP 14mm head studs to achieve the required torque necessary for proper installation.3. Due to the required torque, any block that was previously honed will need to go to the next size overbore.4. Future servicing will require cylinder head resurfacing due to an imprint left from the Fire-Lock rings.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"IAG Performance","offers":[{"title":"Default Title","offer_id":48066705260762,"sku":"IAG-ENG-S1024","price":6999.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0828\/8623\/0234\/files\/IAG-ENG-S1024-01__66951.1747754210.1280.1280.jpg?v=1781530707"}],"url":"https:\/\/www.iagperformance.com\/collections\/iag-built-fa24-short-blocks.oembed","provider":"IAG Performance","version":"1.0","type":"link"}
