IAG’s 950 EJ25 2.35 L Destroked Closed Deck Short Block delivers track-level power, supporting up to 950 BHP, while still offering the dependability needed for everyday driving. This hand assembled block is based off of our IAG 950 short block, and features a 2.0L FHI crankshaft, custom IAG Spec +2mm H-beam forged connecting rods and ARP 625+ rod bolts. Also included in the assembly are JE 99.75mm FSR 2618 custom pistons that have been treated with electroless nickel-plating, creating a hard-wearing surface that offers detonation resistance and heat reflection. This short block strikes the perfect balance for street use along with high-revving racing applications, offering unmatched reliability and longevity. With +2 longer rods, and 2.0L FHI crankshaft, IAG’s Destroked Short Block decreases piston speed, optimizing the rod-to-stroke ratio. This adjustment enhances key engine dynamics such as aspiration, combustion efficiency, and component wear. In terms of performance, this means increased power output, extended ring life, and the ability to rev up to 8,500 RPM making this short block an ideal choice for track days, rally events, or drag racing applications.
