IAG Stage 1 Short Block


The IAG Stage 1 Short Block is perfect for lightly modified EJ25 Subaru's that need a basic and reliable performance short block. Subaru turbo engines are commonly known for piston ring land failures and if gone unchecked lead to rod knock and total engine failure due to oil starvation from blow by. IAG's Stage 1 Short Block includes upgraded forged pistons along with performance main and rod bearings that replace the OEM components that are prone to common failure on Stage 2 and up vehicles. Each IAG Stage 1 Short Block starts with new Subaru 2.5L 99.5mm bore EJ25 engine case halves as standard. The short block is measured and assembled using a new 2012+ Heat Treated Subaru 2.5L STI crankshaft that is matched to ACL or King main bearings. Early style OEM STI rods are utilized along with ACL or King rod bearings. The case halves are sealed with new OEM 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 1 Short Block has a power output rating of 475BHP.

*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.

Optional Shipping Methods:

Red Carpet Service - IAG Pelican Case (Recommended):
Subaru EJ25 Seal Kit


Red Carpet Service / IAG Pelican Cases are a premium shipping option offered by IAG. Your IAG short block is shipped via a returnable polypropylene military grade IAG Pelican case, which provides optimal protection while in transit. Please contact an IAG sales associate at (410)-840-3555 within 2 business days of your purchase to provide credit card confirmation and approval for Pelican shipping - further details and logistics are explained in our Post Sale PDF document, which can be found below. The IAG Pelican case must simply be returned to IAG within 7 days of the receipt of your engine and carries no additional cost vs. cardboard box shipping. If the case is not returned in the required timeline, a core charge of $399 is placed on your card.

Cardboard Box:
Blocks can alternatively be sent in a standard cardboard box, but bear a greater risk of damage in transit. While cost is the same, we suggest a Pelican case that ensures safe transit.

Please review the PDF document below regarding installation, break-in procedures, warranty information, and our Pelican Case Shipping Service. After ordering your block, please call our sales team at 410-840-3555 to approve Pelican shipping and secure the safest shipping method in the aftermarket!

Great Experience August 15, 2016
Reviewer: Matt from Hartford, CT United States  
Shipping time was exactly as described, and opted for the "red carpet" delivery option. Pelican case guarded the engine well, as well as making it easier to move from my deck down into my garage... it had an extendable handle and wheels!

Very friendly staff as well, would definitely work with IAG again as well as recommend them.
