800 FA20 DIT Closed Deck Long Block Engine

The IAG Performance Hand-Built 800 Subaru FA20F (DIT) is engineered for modified WRX vehicles, offering a complete, valve cover to valve cover, timed crate engine. This long block package is designed for significant ease of installation, providing a true plug-and-play solution for 2015+ Subaru WRX owners. Constructed with an aluminum engine block, aluminum crankshaft, and aluminum cylinder heads, this performance-grade engine features forged steel H-beam connecting rods and aluminum pistons. The IAG 800 heads boast CNC-machined combustion chambers, intake runners, and exhaust runners for optimized airflow. Key specifications include a 86.1mm bore diameter, 30mm exhaust valves made of stainless steel, and a power rating of 800 BHP. IAG has simplified the installation process, especially given the FA20F's complex timing system. All new timing components are pre-installed, allowing mechanics to focus on swapping manifolds, sensors, injectors, and external accessories. Most installations can be completed in a single day. This long block is specifically designed for the 2015-2021 Subaru WRX models, including Base, CVT, EyeSight, Limited, Premium, Raui Edition, STI, Sport, Sport-tech, and Sport-tech RS trims. IAG's Standard Long Block Workmanship Warranty covers the engine for 12 months or 12,000 miles. An extended warranty of up to 24 months/24,000 miles is available when purchased, installed, and tuned by an IAG Certified Installation Facility.
