{"title":"Motor Builds","description":"\u003cp\u003eThe best motor build for a WRX, STI, or Evo is a short block matched to the exact engine and the power the car will run: an IAG staged or closed-deck Subaru block for an EJ25, FA20, or FA24 build, a MAPerformance staged shortblock for a 4G63 or Evo X build, or a factory Subaru OEM block for a stock rebuild. IAG and MAPerformance supply most of this collection.\u003c\/p\u003e\n\u003cp\u003eA motor build starts below the cylinder heads. A short block is the assembled block with crank, rods, and pistons, ready for your heads and accessories. A long block adds the heads.

It's a well-known fact that the OEM oil pickups often crack and fail which, in most cases, destroys your engine from lack of oil pressure. To avoid the cracking failures seen in the OEM oil pickup tubes, the Tigwerks oil pickup is manufactured from heavy-gauge steel tubing that is 3x thicker than OEM. Additionally, it features a flange machined from 3\/8\" 1018 CR steel to mate with the block, sealed with a Viton O-ring. The integrated heavy-duty mounting bracket uses two mounting points rather than the OEM single mounting point. Furthermore, the oil pickup features a formed bottom with an OEM style mesh screen for proper filtration. The TIG-welded oil pickup's increased material thickness, matched with the two-point heavy-duty mounting bracket, helps ensure that it does not fatigue and fail over time like an OEM unit.\u003cbr\u003e\u003cbr\u003eThe IAG Oil Control Baffle and Windage Tray System is designed to limit potential blow-by and prevent oil starvation in your Subaru's WRX \/ STI EJ engine during high rpm and high g-force driving. Through the use of Viton one-way flapper valves on our baffle and louvers in our windage tray, oil is prevented from reentering the upper crankcase area and is directed down into the oil pan to ensure plentiful supply to the oil pickup. IAG's integrated two-piece Oil Control Baffle and Windage Tray System is designed to work with our own oil pickup, as well as other oil pickups*. The baffle fits neatly in the engine crankcase area, allowing normal installation of the OEM oil pan and popular aftermarket pans*.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eOil Pickup \u0026amp; Baffle Install Notes\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eEJ20 Subaru WRX engines require EJ25 oil pans for fitment\u003c\/li\u003e\n\u003cli\u003eIAG oil pickup spacer (Part# IAG-ENG-2081SP) is required when using IAG oil pickup with Killer B Oil Pan.\u003c\/li\u003e\n\u003cli\u003e*Does not work with Moroso oil pans or pickups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eOil Pump Option:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv id=\"s-e5f58c98-c770-41f7-9abc-3c2e59856598\" class=\"shg-c shogun-image-container    shg-align-center\"\u003e\u003cimg src=\"https:\/\/i.shgcdn.com\/5488923a-f710-403b-a616-596627901385\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\" class=\"shogun-image shogun-lazyloading shogun-lazyloaded\" alt=\"\" height=\"\" width=\"\" data-src=\"https:\/\/i.shgcdn.com\/5488923a-f710-403b-a616-596627901385\/-\/format\/auto\/-\/preview\/3000x3000\/-\/quality\/lighter\/\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"shg-c\" id=\"s-1211abca-9eba-4889-87dd-a2f1e907a3f1\"\u003e\n\u003cdiv class=\"shg-rich-text shg-theme-text-content\"\u003e\n\u003cp\u003eThe 11mm Subaru Oil pump is one of the most popular off the shelf pumps to use on EJ25 engines.

IAG completely disassembles the new oil pump including pulling the rotors, backing plate \u0026amp; pressure relief valve. Next, the main body is fixtured in our in-house 5-Axis Centroid CNC machine where the inlet and outlet passageways are CNC ported. This allows for a larger, more consistent pathway for the oil into and out of the gerotor internals and helps to prevent cavitation. The Oil Pump Outlet where it meets the engine block is also CNC “Port Matched”, for a perfect transition into the engine block. The Inlet and Outlet sides of the gerotor are also opened up on the CNC mill to reduce inlet side cavitation, and to reduce outlet side pressure drops.\u003c\/p\u003e\n\u003cp\u003eThe pressure relief valve piston is REM Polished, which provides a non-directional, low Ra, polished finish.

The rotors are measured and checked to be within the manufacturer's specification - aka Blueprinted, and installed next.

It's a well-known fact that the OEM oil pickups often crack and fail which, in most cases, destroys your engine from lack of oil pressure. To avoid the cracking failures seen in the OEM oil pickup tubes, the oil pickup is manufactured from heavy-gauge steel tubing that is 2x thicker than OEM. Additionally, it features a flange machined from 3\/8\" stainless steel to mate with the block, sealed with a Viton O-ring. The integrated heavy-duty mounting bracket uses two mounting points rather than the OEM single mounting point. Furthermore, the oil pickup features a formed bottom with an OEM-style mesh screen for proper filtration. The TIG-welded oil pickup's increased material thickness, matched with the two-point heavy-duty mounting bracket, helps ensure that it does not fatigue and fail over time like an OEM unit.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eThe IAG Oil Control Baffle and Windage Tray System is designed to limit potential blow-by and prevent oil starvation in your Subaru's WRX \/ STI EJ engine during high rpm and high g-force driving. Through the use of Viton one-way flapper valves on our baffle and louvers in our windage tray, oil is prevented from reentering the upper crankcase area and is directed down into the oil pan to ensure plentiful supply to the oil pickup. IAG's integrated two-piece Oil Control Baffle and Windage Tray System is designed to work with our own oil pickup, as well as other oil pickups*.

The IAG Stage 2.5 short block builds off our Stage 2 Tuff block's strengths by adding our proprietary closed deck system. This system strengthens and supports the cylinder walls to prevent cracks that can occur with increased cylinder pressures. (This is the most common issue when increasing horsepower.) The Stage 2.5 EJ20 Short Block also features 92.5mm JE Forged Pistons and IAG Spec H beam connecting rods, along with ACL or King Race bearings.

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.

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.
