DESIGNED FOR STRENGTH

Engineered to meet the demands of stock or modified FA20 DIT Subaru WRXs, the IAG 600 Short Block offers a robust bottom end solution capable of handling elevated cylinder pressures resulting from added boost. Featuring IAG Spec H-Beam forged connecting rods, this short block provides enhanced durability and resilience. With upgraded connecting rods and race bearings, it can effectively manage the increased engine load generated by larger turbochargers or heightened boost levels, surpassing the reliability of OEM rods and pistons found in stock short blocks.

ENGINEERED WITH 100% NEW COMPONENTS

Every IAG 600 Short Block commences with pristine FA20 DIT Subaru 2.0L, 86mm stock bore engine case halves as the standard foundation. Meticulously prepared, the case halves undergo precise boring and honing to 86.1mm specifications before being meticulously measured and assembled with a new 2015+ Subaru 2.0L FA20 crankshaft, meticulously matched to ACL or King race main bearings. Featuring IAG Spec H-Beam Connecting Rods equipped with ARP2000 rod bolts, complemented by ACL or King race rod bearings, the short block ensures robust construction. To ensure a secure seal, the case halves are fastened with new OEM main case bolts and sealant. Finally, the assembly is completed with the inclusion of IAG Spec JE FSR 86.1mm Forged Pistons, meticulously selected, measured, and installed to culminate the short block construction.

 

ENHANCED OIL PASSAGES FOR IMPROVED OILING

Sufficient oil circulation is paramount for both performance and reliability. Recognizing the limitations of the original Subaru OEM cases in terms of oiling, our team of machinists meticulously examines and enhances the internal oil passages of every new OEM case employed in the construction of the IAG 600 Short Block. This meticulous process guarantees optimal flow and enhanced reliability, addressing any deficiencies present in the original design.

DURABLE FORGED PISTONS ENGINEERED FOR BOOST

In each IAG 600 Short Block, you'll find IAG Spec JE FSR 86.1mm Forged Pistons, meticulously crafted for resilience. Constructed from 2618 T6 Alloy, these high-strength pistons are purpose-built to endure heightened cylinder pressures associated with increased boost. FSR forgings not only mitigate mass and wear induced by friction but also maintain robustness. Achieved through an innovative asymmetrical skirt design, these pistons shed weight significantly compared to traditional full-round skirts. Featuring smooth flowing radii on the domes and dishes, this design enhances flame travel for optimized combustion. Securing the pistons to the rods are .905 x 2.250" x .150" wall carbon steel wrist pins equipped with Tru Arc locks, ensuring steadfast assembly.
