This engine provides a straightforward \"drop-in\" solution for those looking to upgrade their 2018-2021 Subaru STI. 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. With +2 longer rods, and 2.0L FHI crankshaft, IAG’s Destroked Long Block decreases piston speed, optimizing the rod-to-stroke ratio. This adjustment enhances key engine dynamics such as aspiration and combustion efficiency, while minimizing component wear. In terms of performance, this means increased power output, extended ring life, and the ability to rev higher—making this long block an ideal choice for track days, rally events, or drag racing applications.\r\n\u003cul\u003e\t\u003cli\u003eThese engines offer significant ease of installation for customers seeking a complete \"drop-in\" engine package for their Subaru
