| Manufacturer's Description: 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 and are all balanced and blueprinted. Finally, the case halves are sealed with new OEM main/case bolts and sealant. If you plan to use the IAG 750 Short Block with EJ20 Cylinder Heads, make sure to select the "Hybrid Pistons" option at checkout. These specially designed JE pistons allow the use of EJ20 cylinder heads without the requirement for a chamber matching service to be performed to the cylinder heads. This option is great for international clients who are not able to send their cylinder heads in for modification. This also works great for USDM EJ20 owners who prefer to use a 2.5l short block. The 9.5:1 Compression JE FSR piston set includes .905 x 2.250 straight wall carbon steel wrist pins with Tru Arc locks along with a complete ring set. |
