IAG has developed a process to greatly improve the strength of the OEM Subaru EJ25 Case Halves to combat the effects of high cylinder pressures brought on by increased power and boost. Our proprietary \"Closed Deck\" System works by supporting the top of the cylinder in the weakest areas and prevents movement and expansion which can lead to cracks and failures. Despite the additional material supporting the cylinder walls, there is no concerns with overheating or coolant flow because the area around the middle of the cylinder still maintains the same coolant area. The custom IAG closed deck inserts are machined with holes for oil and coolant to pass through the same as stock. The IAG 950 Closed Deck Case takes the strength one step further by adding provisions for our race-proven Fire-Lock™ head gaskets system, along with modifications for 14mm head studs. If you're one of those people who prefer to do your own builds we now offer our legendary closed deck case halves for purchase separately. Simply install your crank, rods, and pistons to your own specifications and be confident that the case halves will take the power and prevent common cylinder wall failures.\u003c\/p\u003e  \u003cp\u003e\u003cstrong\u003eTHE IAG CLOSED DECK PROCESS\u003c\/strong\u003e\u003c\/p\u003e  \u003cp\u003eThe IAG Closed Deck conversion is performed 100% in-house by our engineers and experts using state-of-the-art equipment. The IAG Closed Deck starts with a new OEM EJ25 bare case. The case is loaded and fixtured to a 4th axis rotary indexer in our Haas VF4-SS CNC Vertical Machining Center. It is supported by the main journals using a precision ground 2-inch bar and tailstock which ensures the datum is the main journals. This method gives us a true reference point to perform all machining operations. A Rennishaw probe is utilized to check that the case is fixtured true, and once confirmed the machining process begins.\u003c\/p\u003e  \u003cp\u003eOnce the case is fixtured, the first step is to mill out 12 pockets for CNC inserts. Rather than attempting to install inserts into an inconsistent cast case, the pockets are milled out to exact dimensions creating a consistent area that accepts our precision inserts. Once the pockets are machined, the case is removed from the mill and placed into a block oven at a low temperature. Our pre-machined closed-deck inserts are simultaneously chilled using dry ice. When the case and inserts have reached our desired temperature, they are moved into our install station, which holds the block and lightly presses the inserts into position on one side of the deck surface. This process is repeated on the other side and then the partially completed case is moved to a cooling rack. In the next step of our process, the case is loaded and fixtured back into the VF-4SS after reaching room temperature. During this stage, the flanges left from machining the inserts are milled close to the case deck surface. Features such as coolant passages and case bolt access positions are machined. Finally, each deck surface is machined true and flat using a Poly Crystal Diamond insert.\u003c\/p\u003e  \u003cp\u003e\u003cstrong\u003eFIRE-LOCK™ READY\u003c\/strong\u003e\u003c\/p\u003e  \u003cp\u003eThe IAG 950 EJ25 Closed Deck Case features our provisions for our propietary \"Fire-Lock™\" Head gasket system.

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\n\n\u003cp\u003e \u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eBUILT WITH 100% NEW COMPONENTS\u003c\/strong\u003e\u003c\/p\u003e\n\n\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\n\n\u003cp\u003e \u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eNEVER WORRY ABOUT HEAD GASKET FAILURES\u003c\/strong\u003e\u003c\/p\u003e\n\n\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\n\n\u003cp\u003e \u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCLOSED DECK FOR EXTRA STRENGTH\u003c\/strong\u003e\u003c\/p\u003e\n\n\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\n\n\u003cp\u003e \u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003ePISTONS SPECIALLY DESIGNED WITH POWER IN MIND\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eThe pistons used in the IAG 1000 FA24 Short Blocks are specifically designed to support the rigors of racing.
