The IAG 950 EJ20 Short Block is the ultimate "weekend racer" block. Built to withstand up to 950 BHP, this is our strongest "Street" short block offering. The IAG 950 short block features +2mm IAG Spec H-Beam forged connecting rods, IAG-Spec JE Pistons with electroless nickel plated coating with H13 tool steel wrist pins, and our venerable "Fire-Lock" head gasket system for 14mm head studs. Each IAG 950 short block is hand assembled using ACL or King rod and main bearings. This combination of parts makes the IAG 950 the perfect block for drag or road racing. These blocks are ideal for EJ20 WRX owners looking to race their vehicles on the weekends and are designed to be used with EJ20 2.0l cylinder heads. The IAG 950 Short Block starts with brand new Subaru 2.0L engine case halves. Our machinists machine the assembled case halves in our Haas VF-4SS CNC mill to accept the IAG Closed Deck inserts, transforming the block into a solid deck. Next, a deck pair of deck plates are attached and the short block is bored and honed to 92.5mm in our in-house Sunnen SV-30 computer controlled cylinder hone. IAG's in-house honing process allows us to set custom piston to wall clearances to ensure quiet operation and reduced oil consumption. The Haas mill also cuts a groove at the top of each cylinder to accept the Fire-Lock head gasket rings and drills each head bolt hole for 14mm head studs. The modified case halves are then assembled using a new Subaru EJ20 2.0L crankshaft and IAG-Spec Tuff H-Beam +2mm connecting rods with ARP 625+ rod bolts. IAG Short blocks feature ACL or King Race rod and main bearings. Finally, the case halves are sealed with new OEM main/case bolts and sealant.
