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 also features 99.75mm 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. The IAG 750 Short Block starts with brand new Subaru 2.5L 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 99.75mm 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 2017+ Subaru 2.5L nitride treated STI 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.","brand":"IAG Performance","offers":[{"title":"Default Title","offer_id":43943456178298,"sku":"JGJS_IAG-ENG-S750","price":4999.99,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0771\/8703\/files\/77842da665ff4.jpg?v=1744703794"},{"product_id":"iag-600-fa20-dit-subaru-short-block-for-2015-21-wrx-600-bhp","title":"IAG 600 FA20 DIT Subaru Short Block for 2015-21 WRX - 600 BHP","description":"The IAG 600 Short Block is designed for stock or modified FA20 DIT Subaru WRXs that need a stronger bottom end to support increased cylinder pressures created by additional boost pressure. The IAG 600 short block features IAG Spec H-Beam forged connecting rods.
