{"product_id":"iag-550-long-block-engine-oil-pump","title":"IAG 550 Long Block Engine Oil Pump","description":"The IAG Performance 550 Long Block Engine is a comprehensive, \"drop-in\" crate engine solution for Subaru WRX, STI, Forester XT, and Legacy GT models, designed to support up to 550 BHP. This engine is built for modified EJ25 Subarus requiring a stronger foundation to handle increased cylinder pressures from higher boost levels.\n\nAt its core is the IAG 550 Short Block, constructed with brand new EJ25 Subaru 2.5L case halves and a new 2017+ Subaru 2.5L nitride-treated STI crankshaft. It features 99.5mm IAG-Spec JE forged pistons, crafted from 2618 T6 Alloy with an asymmetrical skirt design for reduced weight and improved flame travel. Forged IAG Spec H-Beam connecting rods with ARP2000 rod bolts and ACL or King race bearings are utilized to reliably handle the additional engine load from larger turbochargers or increased boost.\n\nThe included IAG 550 Cylinder Head package starts with new OEM Subaru WRX STI castings. These heads are CNC machined in-house for cam clearance, feature a multi-angle valve job for GSC's standard 36mm intake and 32mm exhaust valves, and have their decks resurfaced. The valvetrain is upgraded with GSC components, including GSC S1 camshafts, IAG Stage 1 valve springs with titanium retainers, and OEM valve keepers and lifter buckets. An 11mm ARP 2000 head stud set and all necessary gaskets for final assembly are also included.\n\nThis engine package is suitable as an entry-level replacement for engines that have suffered catastrophic failure or for builds with basic bolt-on parts aiming for up to 550 BHP. The GSC S1 camshafts are designed to enhance power and torque across the entire RPM range, making them ideal for upgraded stock-frame turbos or builds up to 500 WHP.","brand":"IAG Performance","offers":[{"title":"Default Title","offer_id":52688780329272,"sku":"IAG-ENG-L550V","price":9999.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/664207824.webp?v=1784895763","url":"https:\/\/store.motormia.co\/products\/iag-550-long-block-engine-oil-pump","provider":"MOTORMIA","version":"1.0","type":"link"}
