IAG Performance IAG 750 EJ20 Subaru Closed Deck Short Block For 2002-05 WRX - 750 BHP IAG-ENG-S755
$6,892.99
The IAG 750 Short Block is designed to solve the majority of common problems which plague modified EJ20 engines, especially at higher horsepower levels. The IAG 750 short block builds off our IAG 550 block's strengths by adding our proprietary closed deck system. This system strengthens and supports the cylinder walls to prevent cracks which can occur with increased cylinder pressures. (This is the most common issue when increasing horsepower.) The IAG 750 EJ20 block also features 92.5mm JE Forged Pistons and IAG Spec H beam connecting rods, along with ACL or King Race bearings. These components also significantly strengthen the common failure points such as cracked ring lands and spun bearings. These blocks are ideal for EJ20 WRX owners looking to get the most out of their daily drivers and are designed to be used with EJ20 2.0l cylinder heads. The IAG 750 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 modified case halves are then assembled using a new Subaru 2.0L OEM crankshaft and IAG-Spec Tuff H-Beam connecting rods with ARP 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.
