DETAILS

The IAG Performance hand-built Subaru 950 2.35L Destroked Long Block Engine package is a complete, valve cover to valve cover, crate engine. This engine provides a straightforward "drop-in" solution for those looking to upgrade their 2002-2014 Subaru WRX, 2004-2021 Subaru STI, 2004-2013 Subaru FXT, or 2005-2009 Subaru LGT. This long block features a combination of our proven IAG EJ25 2.35L Destroked Closed Deck Short Block and IAG 950 Cylinder Head packages, along with a full range of carefully selected high-performance components to complete the assembly. When paired with our Long Block Installation Packages, you’ll have a true plug-and-play solution to get you back on the road, FAST! All components included are BRAND NEW and there is NEVER A CORE CHARGE required.

IAG’s 950 2.35L Destroked Long Block Engine package delivers track-level power, making it ideal for high-performance applications that support up to 950 BHP. This comprehensive Long Block package features our IAG 950 Closed Deck Short Block that utilizes a brand new Subaru EJ25 engine case that is converted to closed deck and is bored and honed to 99.75mm. The IAG 950 2.35L block features 14mm head stud machining, as well as our Fire-Lock™ gasket solution that 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 combination of the alloy compression shims and gaskets assure maximum sealing for Subaru EJ25 turbocharged engines. The IAG 950 internals include custom JE 99.75mm FSR 2618 pistons, JE Pro Seal Ring Set, along with .240" H13 tool steel wrist pins. Also included are custom IAG spec +2mm H-beam forged connecting rods with 625+ rod bolts, 2.0L FHI crankshaft, ACL Race Bearings and Standard FHI Subaru case bolts.

The block is then paired up with our IAG 950 Fully CNC Ported Cylinder Heads to deliver maximum flow for high horsepower applications. The heads start as brand new Subaru OEM cylinder head castings that are CNC machined and resurfaced. The heads are outfitted with GSC valve train components, consisting of +1mm oversized intake and SuperAlloy exhaust valves, IAG Beehive Springs, as well as GSC Billet Stage 2 camshafts and Kelford DLC coated buckets. To complete the package, we add an IAG / ARP 14mm head stud set and all the required gaskets for the final valve cover-to-valve cover assembly.
