IAG Stage 2 Short Block


The IAG Stage 2 Short Block is designed for modified EJ25 Subaru's that need a beefed up performance short block. The IAG Stage 2 short block builds on the Stage 1's strengths by adding ACL Race bearings and Brian Crower Sportsman H-Beam forged connecting rods. The upgraded rods and bearings are able to support additional engine load produced by larger turbochargers that the OEM STI rods cannot support reliably. Each IAG Stage 2 Short Block starts with new Subaru 2.5L 99.5mm stock bore EJ25 engine case halves as standard. The short block is measured and assembled using a new 2012+ Subaru 2.5L heat-treated STI crankshaft that is matched to ACL or King race main bearings. Brian Crower Sportsman H-Beam rods and ARP2000 rod bolts are utilized along with ACL or King race rod bearings. The case halves are sealed with new OEM main case bolts and sealant. Finally Manley 99.5mm Platinum Series Forged Pistons are spec'd and installed finishing off the short block.

The IAG Stage 2 Short Block has a power output rating of 650BHP.

*All IAG Short Blocks are balanced and blueprinted.

Compression Ratio: 8.5:1 on D Cylinder Heads (EJ255)
Compression Ratio: 8.2:1 on B, V and W EJ257 Heads with standard thickness gasket.

Just fantastic! November 30, 2016
Reviewer: Will from Arizona  
Where to start: The shipping was quick and very well done, the blocks comes in a very protective military grade pelican case, sealed and wrapped in plastic, which is fantastic. However whats even better, is the people. Kieth was very helpful in answering all my questions and even troubleshooting an issue the installer encountered. The block is quite, and feels great. I will update after the break-in period is over and I really get a chance to drive it. 10/10.

Great communication to the customer, and it's nice knowing that the motor is shipped with the protection of a Pelican Case. I can't wait to get this motor assembled and installed.
