IAG’s 1150 EJ25 2.35L Destroked Closed Deck Short Block is built for power, capable of handling up to 1150 BHP. While still a streetable block, the 1150 is optimized for the track. This hand assembled block is based off of our 1150 short block and features an IAG Spec billet 75mm crankshaft, custom IAG Spec +2mm Tri-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 strengthened short block, combined with a billet crank, race bearings, along with forged connecting rods and pistons delivers a rock-solid foundation that is able to endure intense engine loads generated by large turbochargers and high-powered racing conditions, including competition drag racing. With custom IAG Spec +2mm Tri-beam forged connecting rods and IAG Spec billet 75mm crankshaft, IAG’s Destroked Short 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 short block an ideal choice for track days, racing, or competition drag racing applications. Our recommended maximum rev limit is 9000 rpm for these short blocks. IAG’s Destroked Short Block decreases piston speed, optimizing the rod-to-stroke ratio.
